Milwaukee specifies an electronic clutch for kickback protection and overload protection to help maximize motor life. The anti-vibration side handle is designed for user comfort and safety.
This is a tool-only model, so plan for a compatible M18 battery if you don't already have one. Its 5/8"-11 spindle works with common grinding accessories, but match the wheel to the tool and the job.
Choose it for a general cordless setup with protective features and familiar wheel sizes. If you need adjustable speed or a brake, compare it with the 2889-20 and 2888-20.

- Tool-free guard and accessory changes
Cons
- Tool only, so a compatible M18 battery is needed
The 2889-20 suits jobs where you want to adjust wheel speed instead of running at one setting. It offers five settings from 3,500 to 8,500 RPM, along with a brake that stops most wheels in less than 2 seconds.
Tool-free guard adjustment lets you reposition the guard without a tool. FIXTEC nut technology also allows tool-free accessory changes.
Its slide switch is designed to reduce user fatigue. Consider the switch style as part of your choice, especially if you prefer a paddle control.
Choose this model when variable speed and braking are priorities. It is tool-only, so factor in a compatible M18 battery.
Milwaukee 2888-20 18V Variable Speed Grinder: Best for paddle-switch speed control
- Five variable speed settings
- 8,500 RPM maximum speed

It includes a guard, handle, tool and wrench. The tool still needs a compatible M18 battery.
Compared with the 2889-20, the 2888-20 has a paddle switch and includes accessories. The 2889-20 adds tool-free guard adjustment and FIXTEC accessory changes.
Choose the 2888-20 if you want variable speed and a paddle switch. Check wheel and battery compatibility before buying.

Pros
- Supports wheels up to 6 in
- Braking grinder
- Paddle switch
Cons
- Tool only, so a compatible M18 battery is needed
The 3670-20 supports 4-1/2 in and 6 in wheels. That gives it a larger maximum wheel size than the other cordless picks in this roundup.
It is an 18V braking grinder with a paddle switch and a maximum speed of 9,000 RPM. Check that your accessories match the tool's specifications.
This model is tool-only, so it needs a compatible battery. Its wider wheel range may suit your work, but the material, cut and work area still matter.
Choose it if you want one grinder for both 4-1/2 in and 6 in wheels. For 4-1/2 in or 5 in work, a smaller model may suit your needs.

- 5 in flathead design
- Low profile for tight spaces
- RAPIDSTOP brake stops most wheels in less than 2 seconds

- Low-profile flathead design
- RAPIDSTOP brake
- 5 in wheel size
Cons
- Specialized shape may be unnecessary for open work areas
The 2886-20 is designed for tight access, where its low-profile 5 in flathead design may reach spaces a traditional grinder head cannot. That profile is the clearest reason to choose it over a standard angle grinder.
It has a RAPIDSTOP brake that stops most wheels in less than 2 seconds. Its product description gives a maximum speed of 8,500 RPM and says it generates 11A corded power.
This is a tool-only cordless model, so you'll need a compatible M18 battery. Consider whether your work regularly places the wheel near a wall, frame or another obstruction.
Choose the 2886-20 when access is the problem you're solving. For open work, the 2880-20 offers common wheel options and a general-purpose shape.

This grinder is tool-only, so it requires a compatible battery. Speed alone should not determine your choice; match the wheel to its rated use and follow the tool instructions.
Choose it if a high-speed cut-off grinder fits your tasks. For variable speed, compare the 2889-20 or 2888-20 instead.

Pros
- Corded power
- Tool-free guard adjustment
- Several accessories included
Cons
- A cord limits movement compared with a cordless grinder
The 6142-30 is the corded pick for buyers who want a 120V grinder without relying on a battery. It fits a 4-1/2 in wheel and reaches a maximum speed of 10,000 RPM.
It includes a side handle, Type 27 guard, spanner wrench and flanges. The guard adjusts without a tool, and its soft-grip handle is designed for comfort and control.
A cord can limit movement around a large workpiece or outdoor area, so plan where you'll plug in before choosing this model. Its corded power may suit a shop station or work area with convenient outlets.
Choose it if you prefer a corded setup and a 4-1/2 in wheel. If portability matters more, compare the M18 models and your battery setup.
Which Milwaukee grinder features matter most?
Choose variable speed when you want to change the wheel's pace, and braking when a quick stop is useful after releasing the control. The 2889-20 and 2888-20 offer both, while the 2880-20 has a clutch and overload protection.
A flathead profile may help when the grinder head needs to reach a tight space. The 2886-20 is the 5 in flathead pick here, while the 3670-20 supports wheels up to 6 in.
Switch style can also affect your choice. Several picks use a paddle switch, while the 2889-20 has a slide switch designed to reduce user fatigue.

How to choose a Milwaukee angle grinder
Start with your most common job and the wheel size it calls for. Then decide whether you want battery power, corded power, variable speed, braking or a profile for tighter access.
What size Milwaukee angle grinder should you get?
Choose the wheel size that matches the work and the accessories you can use. These Milwaukee models cover 4-1/2 in, 5 in and, for the 3670-20, 6 in wheels.
A larger wheel can change the tool's reach and the area it covers. Compare our angle grinder size guide before choosing, and use only wheels approved for your grinder.
Should you choose a cordless or corded Milwaukee grinder?
Choose cordless if you need to move around without a power cord and have, or plan to get, compatible batteries. Choose the 6142-30 if a 120V corded tool fits your workspace.
Most cordless tools here are tool-only. The 2680-21P is the kit option with a battery and charger, so check what you already own before deciding.
Do variable speed and a brake matter?
Variable speed lets you select from different speed settings, while a brake stops the wheel after releasing the control. The 2889-20 and 2888-20 combine both features, with different switch and accessory details.
If your work calls for a fixed high speed, the 2686-20 reaches 11,000 RPM. Match the wheel and speed to the tool's rated use, and follow its instructions.
When is a flathead grinder useful?
A flathead grinder may help when the grinder head needs to reach around an obstruction or into a tight space. Milwaukee's 2886-20 uses a low-profile 5 in design for that purpose.
If your work is mostly on open surfaces, a standard grinder may suit you better. Consider the flathead model when restricted access is a recurring part of the job.
Safe setup for a Milwaukee grinder
Use the guard, handle and wheel type specified for the task, and wear eye and face protection. A grinder can throw sparks and debris, and kickback can happen if the wheel binds or catches.
Check the wheel for damage before use and make sure it fits the grinder's size and speed requirements. Keep sparks away from flammable materials and follow Milwaukee's instructions for battery, accessory and tool use.
Our guide to angle grinder safety and kickback basics covers protective gear, guards and handling. Read it before using a grinder, especially if you're new to cutting or grinding.
Which Milwaukee angle grinder should you choose?
Choose the 2880-20 for a cordless grinder with a clutch, overload protection and 4-1/2 in and 5 in wheel compatibility. Pick the 2889-20 for variable speed and braking, the 2886-20 for tight access, or the 6142-30 for corded 4-1/2 in work.
If your priority is adjustable speed, see our best variable speed angle grinders roundup. Match the model to your battery setup, wheel size and work area before choosing.

Frequently asked questions
Which Milwaukee angle grinder is best for most people?
The 2880-20 is a general-purpose choice if you already use M18 batteries and want a cordless grinder for 4-1/2 in or 5 in wheels. It has a no-lock paddle switch, an electronic clutch for kickback protection and overload protection.
Choose another model if variable speed, tight access, a larger wheel or corded power matters more.
What is the difference between the Milwaukee 2889-20 and 2888-20?
Both offer five speed settings and a wheel brake. The 2889-20 adds tool-free guard adjustment and FIXTEC tool-free accessory changes, while the 2888-20 has a paddle switch and includes a guard, handle, tool and wrench.
Compare the control and accessory details that matter for your work.
Do Milwaukee cordless angle grinders include a battery?
Many cordless grinders here are tool-only, so you need a compatible battery to use them. The 2880-20 works with all M18 batteries, while the 2686-20 is battery powered.
The 2680-21P kit includes a battery and charger, which may suit buyers without those items.
When should you choose a flathead grinder?
Choose the Milwaukee 2886-20 when its low-profile flathead design helps reach a tight space where a traditional 5 in grinder may not fit. The design is its main distinction among these picks.
For open surfaces and general use, compare a standard grinder by wheel size, switch and power source.
Should you get a corded or cordless Milwaukee grinder?
A cordless grinder lets you move without managing a power cord, but most picks here need a compatible battery. The corded 6142-30 runs on 120V power and reaches up to 10,000 RPM.
Choose based on where you work and whether you already own M18 batteries.
