Milwaukee M18 FUEL 2880-20
Milwaukee M18 FUEL 2880-20
An M18 no-lock paddle with both guard types in the box
Why it fits
- 2880-20 leads for M18 users wanting a no-lock paddle switch, brushless motor and documented grinding and cutting guard pieces in one package. Milwaukee lists 8,500 RPM and 4-1/2-inch or 5-inch wheels. RAPIDSTOP braking and an electronic clutch are maker-stated features, not our measured stopping or protection results. The conventional spindle is 5/8-inch-11. The box lists a T27 guard, T1 clip-on guard, side handle, wrench, back flange and flange nut. The manual requires the Type 1 clip-on guard when using a Type 1 wheel. Match the wheel dimensions, mounting hardware and guard to the manual rather than choosing by diameter alone. All M18 batteries are listed compatible, but battery and charger are separate and the box list does not include a wheel. Tool-free guard adjustment and a side handle are documented. A masonry dust shroud is not listed in the box; confirm a maker-approved extraction setup if masonry work decides the purchase. [1] [2] [3]

Bosch GWS13-50VS
Bosch GWS13-50VS
Corded variable speed with named dust-hood options
Why it fits
- GWS13-50VS suits a mains-powered setup where a wide speed range and documented dust-attachment options matter. Bosch lists 13A, 120V, a 5-inch wheel capacity and variable speed from 2,800 to 11,500 RPM. This selected VS model has a lock-on slide switch; it is not the VSP paddle version. The spindle is 5/8-inch-11 UNC. The package lists backing flange, lock nut, spanner wrench, grinding guard and a two-position Vibration Control side handle. The manual identifies metal cutting and concrete surfacing or cutting as applications requiring optional attachments, and requires a Type 41/1A cutting guard for cutting operations. Bosch lists 18DC-5E cutting and 18SG-5E surface-grinding extraction hoods among compatible accessories, separately from the included grinding guard. Confirm the exact hood, wheel and extractor coupling for the work. Constant electronics and restart protection are documented features; there is no measured dust-capture or injury-prevention result here. [4] [5] [6]

FLEX FX3171A-1C Kit
FLEX FX3171A-1C Kit
A battery-and-charger kit with four speed settings
Why it fits
- FX3171A-1C suits buyers starting a FLEX setup who want a battery and charger included. The variable-speed grinder has a no-lock paddle and four stated no-load settings: 3,500, 5,000, 7,000 and 10,000 RPM. Select this A-model kit, not the fixed-speed FX3171 or the bare FX3171A-Z. FLEX specifies 4-1/2-inch or 5-inch wheels and a 5/8-inch arbor; the manual also states a 5/8-inch spindle thread without the pitch. Verify the exact threaded accessory rather than inferring it from diameter. The manual lists Type 27 grinding and Type 41 cutting wheels, with a separate FT311 cut-off guard identified as not supplied. The kit lists a 5.0Ah battery, 160W fast charger, grinding guard, two flanges, wrench, anti-vibration handle and bag. FLEX lists compatibility with its 24V batteries and one-step guard adjustment. The supplied package is not a complete masonry dust-extraction setup; confirm cutting guard, wheel and approved shroud separately. [7] [8] [9]

DEWALT DCG413B
DEWALT DCG413B
A compact 20V MAX paddle with two-stage activation
Why it fits
- DCG413B suits existing 20V MAX users wanting a 4-1/2-inch brushless grinder with a paddle switch. DEWALT documents a two-stage trigger requiring two actions to activate. Its brake and KICKBACK BRAKE are described features; we do not compare measured stop times or claim that they prevent injury. The selected box includes a side handle, hex key, inner and outer flange and 4.5-inch Type 27 guard. The manual’s cutting-wheel chart specifies a Type 1/41 guard for abrasive and diamond cutting wheels and identifies that guard as an extra-cost accessory. Do not treat the included grinding guard as a complete cutting package. Battery and charger are separate. The manual requires accessory speed ratings at least equal to the tool’s marked maximum and matching dimensions and mounting hardware. Exact spindle-thread details and a masonry shroud package were not established here; confirm those with DEWALT before buying the relevant accessories. [10] [11] [12]

Metabo HPT G13VE2
Metabo HPT G13VE2
AC brushless power and six speed settings
Why it fits
- G13VE2 suits corded preparation work where six speed settings and a slim grip are useful. Metabo HPT lists a 12A AC brushless motor, 5-inch wheel size and 2,500–8,500 no-load RPM. It has a slide switch, soft start and a side handle that can mount in three directions. The stated spindle thread is 5/8-inch-11 UNC. Its guard installs or adjusts using a quick-release lever. The package includes a 5-inch depressed-center wheel, wheel guard, filter set, side handle and wrench. The manual distinguishes the 5-inch G13VE2 from the smaller G12VE2; match accessories to this selected model. A removable fine-mesh dust filter is documented for the motor housing; it is not a masonry extraction shroud. Weight descriptions on the page disagree about whether the guard is included, so assembled weight is left out of this comparison. Confirm a compatible cutting guard and dust setup if the project extends beyond the supplied grinding arrangement. [13] [14] [15]

Makita XAG04Z
Makita XAG04Z
An LXT slide switch with a conventional spindle
Why it fits
- XAG04Z suits existing LXT users who prefer a lock-on slide switch and conventional threaded mounting. Makita lists 4-1/2-inch or 5-inch use, 8,500 no-load RPM and a 5/8-inch-11 UNC spindle. This model has no variable-speed dial and no electric brake in its specification table. The maker documents Automatic Speed Change, soft start and Active Feedback-sensing Technology. Those are control features, not measured grinding speed or protection results. The listed package includes a 5-inch INOX grinding wheel, stainless cut-off wheel, side handle, lock-nut wrench and 5-inch tool-less wheel guard. The manual says diamond and cut-off wheels require the appropriate optional cut-off guard. The product page separately lists a clip-on cut-off cover and dust-extraction cutting and surface-grinding accessories. Battery and charger are separate; compatible Makita 18V batteries need the Star symbol. Budget the exact guard and shroud even though a cut-off wheel is included. [16] [17] [18]

DEWALT DWE402
DEWALT DWE402
An 11A corded paddle with optional lock-on operation
Why it fits
- DWE402 suits a corded 4-1/2-inch grinding setup with an 11A AC/DC motor and stated 11,000 RPM. Its paddle has a lock-off lever, but the manual also documents a lock-on button for continuous operation. It is therefore a different switch choice from the no-lock Milwaukee and FLEX. The manual specifies 5/8-inch-11 threaded accessories and 7/8-inch arbor holes for unthreaded accessories, subject to its accessory chart. The selected DWE402 package lists a T27 One-Touch guard, wrench and two-position side handle. It is not the DWE402W wheel bundle; a grinding wheel is not listed in this package. The maker documents one-action guard rotation and tool-free wheel removal. The manual identifies the Type 1 cutting guard as an extra-cost item. Its Dust Ejection System addresses particles entering the tool; it is not an external masonry dust collector. Confirm an approved cutting or extraction setup separately rather than treating a corded grinder as fully equipped. [19] [20] [21]

RYOBI PBLAG02B ONE+ HP
RYOBI PBLAG02B ONE+ HP
ONE+ cutting and grinding wheels in the selected package
Why it fits
- PBLAG02B suits ONE+ users wanting a 4-1/2-inch brushless grinder with a paddle switch and three-position side handle. The official embedded specification lists 9,000 RPM. This is PBLAG02B, not the earlier PBLAG01B. The official description lists a cutting guard, side handle, spanner wrench, grinding wheel and cutting wheel in the package, with tool-free guard adjustment. The listed arbor size is 5/8-inch; thread pitch was not established here. Confirm the exact mount, wheel profile and guard combination for your chosen accessories. It uses the 18V ONE+ platform; the selected B option is tool only and battery and charger are separate. A masonry extraction shroud is not listed in the package. The included cutting equipment does not establish dust capture or cover every masonry accessory, so confirm the approved dust setup before choosing it for that use. [22] [23] [24]

RIDGID R86047B
RIDGID R86047B
A RIDGID paddle with tool-free wheel changes
Why it fits
- R86047B suits RIDGID 18V users who want a 4-1/2-inch brushless paddle grinder. The maker lists 9,000 RPM, electronic braking when the paddle is released, and tool-free wheel and guard adjustment. The specification table says variable speed is not available. The selected package lists a Type 27 grinding wheel, guard and side handle. The stated arbor size is 5/8-inch; exact thread pitch and a dedicated cutting guard were not established here. Confirm the manual’s accessory and guard requirements before planning metal or masonry cutting. All RIDGID 18V batteries are listed compatible, with battery and charger separate. This pick makes most sense for an existing RIDGID setup and the supplied grinding arrangement. A specific masonry shroud and extraction coupling are not established; ask for model-matched confirmation rather than treating tool-free adjustment as universal accessory compatibility.

Makita GA4570
Makita GA4570
Corded X-LOCK for frequent accessory changes
Why it fits
- GA4570 suits a corded bench where tool-free X-LOCK changes are more important than keeping conventional threaded accessories. Makita lists a 7.5A motor, 11,000 no-load RPM, 4-1/2-inch wheels and a lock-on slide switch. There is no variable-speed dial or bind-up control in its specification table. This grinder is only compatible with X-LOCK accessories. It uses a snap-on mount and release lever, rather than a conventional spindle-and-nut setup. The included accessory list names a 4-1/2-inch X-LOCK metal/stainless grinding wheel, side handle and wheel guard. Check that the consumables you need are actually offered in X-LOCK form. The maker lists metal work and brick or masonry cutting among applications. Its manual requires an appropriate optional cut-off guard for diamond or cut-off wheels; the product page lists a 199709-0 clip-on cover separately. Confirm the complete approved cutting and extraction package for masonry. The stated 2-1/2-inch barrel diameter and 11-3/8-inch length describe size, not tested handling. [28] [29] [30]

| Compatibility | The conventional spindle is 5/8-inch-11. The box lists a T27 guard, T1 clip-on guard, side handle, wrench, back flange and flange nut. The manual requires the Type 1 clip-on guard when using a Type 1 wheel. Match the wheel dimensions, mounting hardware and guard to the manual rather than choosing by diameter alone.

The included accessory list names a 4-1/2-inch X-LOCK metal/stainless grinding wheel, side handle and wheel guard. Check that the consumables you need are actually offered in X-LOCK form. [29] |
| Form factor | All M18 batteries are listed compatible, but battery and charger are separate and the box list does not include a wheel. Tool-free guard adjustment and a side handle are documented. A masonry dust shroud is not listed in the box; confirm a maker-approved extraction setup if masonry work decides the purchase. [3] | Bosch lists 18DC-5E cutting and 18SG-5E surface-grinding extraction hoods among compatible accessories, separately from the included grinding guard. Confirm the exact hood, wheel and extractor coupling for the work. Constant electronics and restart protection are documented features; there is no measured dust-capture or injury-prevention result here. [6] | The kit lists a 5.0Ah battery, 160W fast charger, grinding guard, two flanges, wrench, anti-vibration handle and bag.

The included cutting equipment does not establish dust capture or cover every masonry accessory, so confirm the approved dust setup before choosing it for that use. [24] | All RIDGID 18V batteries are listed compatible, with battery and charger separate. This pick makes most sense for an existing RIDGID setup and the supplied grinding arrangement. A specific masonry shroud and extraction coupling are not established; ask for model-matched confirmation rather than treating tool-free adjustment as universal accessory compatibility. [27] | The maker lists metal work and brick or masonry cutting among applications. Its manual requires an appropriate optional cut-off guard for diamond or cut-off wheels; the product page lists a 199709-0 clip-on cover separately. Confirm the complete approved cutting and extraction package for masonry. The stated 2-1/2-inch barrel diameter and 11-3/8-inch length describe size, not tested handling. [30] |
Choose the wheel system and switch first
Diameter is only one part of accessory fit. Milwaukee, Bosch, Metabo HPT and the corded DEWALT document conventional 5/8-inch-11 mounting. Makita GA4570 accepts only X-LOCK accessories. FLEX, RYOBI and RIDGID list a 5/8-inch dimension, but the evidence here does not establish their thread pitch. Verify the exact mounting, wheel profile and hardware before purchasing consumables. [2] [5] [14] [20] [29] [8] [23] [26]
A paddle does not always mean no lock-on. Milwaukee 2880-20 and FLEX’s selected kit specify no-lock paddles. DWE402 has a paddle plus a lock-on button in its manual. Bosch GWS13-50VS and the two selected Makitas use lock-on slide switches. Choose the control layout deliberately rather than inferring behavior from a product photograph. [1] [7] [19] [4] [16] [28]
Variable speed creates another distinction: Bosch offers 2,800–11,500 RPM, Metabo HPT offers six settings across 2,500–8,500 RPM, and FLEX gives four presets. Follow the wheel and manual requirements at every setting. Bosch’s manual requires an accessory rating at least equal to the maximum speed marked on the tool; a lower dial setting is not a substitute for that rating. [4] [13] [7] [12]
Price the complete cutting and masonry setup
Look at guard scope before comparing tool packages. Milwaukee includes a T27 guard and T1 clip-on, while RYOBI lists a cutting guard and both grinding and cutting wheels. The selected DEWALTs include T27 guards and need the documented extra cutting guard for the relevant wheels. FLEX’s manual identifies FT311 as not supplied. Makita XAG04 includes a cut-off wheel, yet its manual still requires an appropriate optional cut-off guard. [2] [23] [11] [21] [8] [17] [18]
For masonry, confirm the exact maker-approved wheel, cutting guard or surface-grinding shroud and extractor connection for the task before buying. Bosch lists separate cutting and surface-grinding extraction hoods. Metabo HPT’s motor filter and DEWALT’s Dust Ejection System address the tool’s internals; neither is an external dust collector. This comparison does not establish dust capture or regulatory compliance for any assembled setup. [6] [15] [21]
Compare the full power package. FLEX FX3171A-1C includes a 5.0Ah battery and charger; the selected Milwaukee, cordless DEWALT, Makita XAG04, RYOBI and RIDGID options need them separately. Bosch, Metabo HPT, DWE402 and GA4570 are corded. Include wheels, guards and extraction accessories in the purchase decision, and compare assembled handling with the battery or cord setup you will actually use.

How we compared.
Source-based comparison of official US product pages and selected operator manuals read October 3, 2026. Pro Tool Reviews’ angle-grinder buying guide treats wheel size and compatible masonry shrouds as important purchase distinctions; that attributed editorial context informed our accessory-first comparison. It is one editorial source, not owner consensus. Milwaukee 2880-20 leads for its no-lock paddle, conventional spindle and included grinding and clip-on cutting guards. Corded variable-speed choices, a complete battery kit and X-LOCK provide different reasons to choose the alternatives. We have not tested cutting speed, brake times, dust capture, vibration or runtime. Specifications and features are manufacturer statements; ranking is independent of commission.
