Product Description
Milwaukee M12 FUEL 1/4 in. Straight Die Grinder
Model Number: 3486-20
The Milwaukee 3486-20 is the M12 FUEL 1/4 in. Straight Die Grinder, sold as a bare tool, built to deliver the cordless performance and compact size that professional service technicians and metalworkers demand. Its POWERSTATE Brushless Motor generates 0.5 HP of output with sustained power and improved torque, driving speeds up to 20,000 RPM for efficient grinding, sanding, deburring, and material removal. Engineered to run 2 in. cutting wheels and 3 in. sanding accessories on a 1/4 in. collet, it handles the everyday die-grinder tasks of weld dressing, port and edge work, rust and burr removal, and detail material removal. The compact, straight-grinder profile improves access in tight spaces, and going cordless eliminates the hoses and compressor a pneumatic die grinder requires, giving real mobility and flexibility around the shop or out on a service call.
Control and ease of use are built in. A 4-mode RPM speed control paired with a responsive variable-speed paddle lets the operator match the speed to the application, from delicate detail work up to aggressive stock removal, for precise control across jobs. An improved ergonomic handle enhances grip and comfort while reducing fatigue during extended use, and a shadowless LED work light maximizes visibility right at the accessory so you can see the cut clearly in dim or awkward spots. Changing accessories is fast thanks to a push-button spindle lock that allows one-wrench accessory changes, cutting downtime between bits and wheels.
As part of the Milwaukee M12 system of over 250 tools, the 3486-20 runs on any M12 REDLITHIUM battery, and it performs best paired with an M12 REDLITHIUM HIGH OUTPUT battery for maximum power and runtime. Please note that this is the bare tool: the battery and charger are not included and are sold separately, though an accessory wrench is included. A kit version with batteries and charger is available separately under catalog number 3486-22. For technicians already invested in the M12 platform, this die grinder delivers corded-rivaling grinding performance with full cordless portability in a tool small enough to reach where larger grinders cannot.
