This Milwaukee grinder comparison covers every angle grinder and die grinder in Milwaukee's current lineup, including corded, M12, and M18 FUEL models. Find the right model for your jobsite. 

Whether you're cutting rebar on a structural steel job, grinding welds in a fabrication shop, or doing precision die work in a tight recess, Milwaukee makes a grinder built specifically for that task.

Milwaukee's angle grinder lineup spans corded tools, standard M18 brushless, and the full M18 FUEL platform. Differences between models come down to switch type, braking, variable speed, ONE-KEY connectivity, and wheel capacity. Here's how each model is designed to be used.

For shop environments and job sites where sustained, uninterrupted power is the priority, corded angle grinders remove the battery management overhead entirely. These are the right call when you're grinding for extended sessions and have access to power.

The 6130-33 is a straightforward corded angle grinder built for everyday cutting and grinding. At 7 amps, it handles light to medium metalwork, tile cutting, and general surface prep without the weight or cost of a high-amp motor. It's a practical choice for tradespeople who want a reliable corded grinder for standard 4-1/2" disc work

Stepping up to 11 amps, the 6142-31 handles denser materials and heavier grinding loads than the 6130-33. Its built-in overload protection monitors the motor under sustained load and helps prevent burnout in production environments where the grinder stays in use all day. The overload system doesn't restrict performance during normal operation — it only engages when the motor is being genuinely pushed past its rated threshold.

The 6088-30 is Milwaukee's large-format corded grinder, built for 7-inch and 9-inch abrasive wheels. At 15 amps it powers through heavy stock removal, concrete grinding, and large-area surface prep where a 4-1/2" wheel doesn't have the coverage. The lock-on switch is designed for extended continuous use where you'd rather not hold the trigger for long periods. This model lives in a different category than the compact grinders — it's a production tool for heavy material removal. 

All M18 grinders share the same battery platform. Your existing M18 batteries work across every model below, and the same packs rotating through your impact wrench, drill, or blower work here too. Model differences come down to motor tier, switch configuration, braking, variable speed, and ONE-KEY.

The 2880-20 is the base model in Milwaukee's M18 FUEL angle grinder lineup. FUEL combines the POWERSTATE brushless motor, REDLITHIUM battery technology, and REDLINK PLUS electronics — which together produce more sustained power output than the standard M18 brushless lineup. The no-lock paddle switch stops the disc immediately when you release, which is the preferred safety configuration for most cutting and grinding applications.

Available in three versions: the 2880-20 bare tool for crews already equipped with M18 batteries, the 2880-22 two-battery kit, and the 2880-21F FORGE kit which bundles the FUEL grinder with Milwaukee's high-cycle FORGE battery for heavy daily use.

The 2881-20 runs the same M18 FUEL motor platform as the 2880-20 but uses a slide switch with lock-on capability. Lock-on is the preferred configuration for sustained grinding passes where you want to maintain tool operation without continuously holding the trigger — common on longer weld grinding runs or sustained surface prep work. Same motor and power output as the 2880, different switch ergonomics.

The 2882 series adds two significant upgrades to the base 2880 platform: active braking and ONE-KEY connectivity. The active brake stops the disc substantially faster after releasing the paddle, which improves both safety and workflow when you're repositioning between cuts. ONE-KEY lets you track tool location, customize speed settings, and manage tool assignment across a fleet. Available as a bare tool (2882-20) and a two-battery kit (2882-22).

The 2883-20 is the slide switch lock-on version of the 2882-20. Identical FUEL motor performance, active braking, and ONE-KEY — just with a lock-on slide switch instead of the paddle. For crews that run sustained cuts and want ONE-KEY fleet management, this is the right configuration.

The 2886-20 uses a flathead motor housing design that puts the body in a lower-profile arrangement for improved access in confined spaces. If you're grinding under equipment, inside structural steel frames, or in any tight clearance where a standard grinder body won't fit, the flathead opens up angles that aren't accessible with a conventional body. Active braking is included. The 5-inch wheel gives slightly more coverage than a 4-1/2" disc.

The 2888-20 adds variable speed control to the M18 FUEL braking grinder platform. Variable speed matters when working with heat-sensitive materials, specialty abrasives that have lower RPM ratings, or polishing applications where you need to dial in wheel speed to the material. Includes active braking. This is the paddle switch version for operators who want speed control without the lock-on configuration.

The slide switch lock-on counterpart to the 2888-20. Variable speed and active braking on the M18 FUEL platform, with lock-on for sustained grinding sessions. For crews doing extended polishing or speed-sensitive material work, this configuration handles those demands with the lock-on convenience built in.

The 3676-20 is the top-specification angle grinder in the M18 FUEL lineup. It expands wheel capacity up to 6 inches, adds a dual-trigger configuration that requires both hands engaged before the tool can run, and combines variable speed, active braking, and ONE-KEY in a single package. The dual-trigger design is built for environments where tool-handling safety protocols are a formal requirement. The 6-inch capacity gives meaningfully more surface coverage for aggressive stock removal and surface prep compared to standard 4-1/2" setups.

Milwaukee's die grinder lineup covers corded, M12, and M18 FUEL models in straight and right-angle configurations. Die grinders handle precision work — weld cleanup, deburring, porting, polishing, and grinding in tight spaces — that angle grinders can't reach. Here's a breakdown of every Milwaukee die grinder available at RedToolStore.com.

The 5196 is Milwaukee's corded die grinder. At 11 amps it delivers more continuous power than any battery-based die grinder in the lineup — no runtime management, no battery swaps, just consistent output for extended industrial use. For fabrication shops, mold and die work, or any application where the die grinder runs for long periods on tough materials, a corded tool with this motor capacity is hard to replace.

Milwaukee's M12 platform keeps the tool compact and lightweight — the right fit for tight spaces, overhead work, and applications where an M18 tool body would be awkward. M12 die grinders share batteries with the rest of the M12 system.

The right-angle configuration on the 3485-20 (bare) and 3485-22 (kit) puts the bit perpendicular to the tool body — essential when working in a cavity, recess, or confined area where a straight die grinder can't reach the work surface. Right-angle die grinders are standard in automotive work, HVAC ductwork, and any application where you're finishing inside a pocket or against a perpendicular surface. The 1/4" collet fits most die grinder accessories.

The 2525-21 sits at the precision end of the Milwaukee die grinder category. It handles detail grinding, engraving, fine polishing, and work with small-diameter accessories that a standard die grinder wouldn't manage cleanly. The M12 platform keeps it compact and cordless. If your work involves intricate material shaping, light material removal in tight areas, or detailed surface finishing, the 2525-21 covers a niche the larger die grinders don't.

The 2939-20 brings M18 FUEL output to a straight die grinder with active braking. The brake stops the bit quickly after releasing the slide switch — useful in precision work where you want the tool to stop at a defined point rather than spinning down gradually. The slide switch suits sustained grinding runs. For applications that need M18 runtime and power in a die grinder format, this is the straightforward M18 option.

The 2984-20 is the most fully-featured die grinder in Milwaukee's lineup. Variable speed lets you dial in the right RPM for the accessory and material — critical when using carbide burrs, mounted grinding points, or specialty bits that have rated speed limits. Active braking, ONE-KEY fleet management, and the M18 FUEL motor round out the specification. The paddle switch gives quick release for repositioning. For varied precision work across multiple materials and accessory types, the variable speed control on the 2984-20 provides flexibility the fixed-speed models don't.

With 23 models across two categories, the right Milwaukee grinder comes down to a handful of practical questions. Work through these and the right model becomes clear.

• Corded or cordless? If you need constant power without battery interruptions and have a power source available, corded models (6130-33, 6142-31, 6088-30, 5196) are the straightforward answer. If mobility, platform compatibility, or jobsite flexibility matters more, the M18 or M12 lineup is the right direction.
• What battery platform are you already running? If your crew is on M18, the M18 FUEL lineup adds grinders without adding a new battery type. If you run M12 for compact tools, the M12 FUEL die grinders fit directly into that ecosystem.
• Do you need active braking? Active braking stops the disc or bit quickly after releasing the switch. For high-frequency cut-off work, safety-focused job sites, or situations where you're repositioning constantly, braking models (2882, 2883, 2886, 2888, 2889, 3676, 2939, 2984) are worth the step up in price.
• Does variable speed matter? Variable speed is valuable for polishing, heat-sensitive materials, and specialty abrasives with RPM ratings. The 2888, 2889, 3676, and 2984 cover those applications.
• Do you need ONE-KEY? For fleet management, job site tool tracking, or locking tools to specific locations, ONE-KEY connectivity on the 2882, 2883, 3676, and 2984 adds real operational value beyond the grinding performance.
• Tight spaces? The 2886-20 flathead design and the M12 right-angle die grinder (3485) are purpose-built for clearance-limited work where standard body geometry won't fit.
• Angle grinder or die grinder? Angle grinders handle cutting, heavy grinding, and surface prep with large-diameter discs. Die grinders handle precision work — deburring, porting, polishing, and detailed material removal — with smaller-diameter bits and accessories.
