Product Description
Milwaukee M12 FUEL 1/4 in. Extended Die Grinder
Model Number: 3487-20
The Milwaukee 3487-20 is the M12 FUEL 1/4 in. Extended Die Grinder, sold as a bare tool, built to deliver cordless grinding performance with the reach to get into places a standard die grinder cannot. What sets this model apart from the straight version is a 4 in. extended shaft that improves access in deep, confined, and hard-to-reach spaces, letting a technician work down into recesses, cavities, and tight assemblies while keeping their hand and the tool body clear of the work. Its POWERSTATE Brushless Motor generates 0.5 HP of sustained output with improved torque, driving speeds up to 20,000 RPM for efficient grinding, sanding, deburring, and surface preparation with 2 in. cutting wheels and 3 in. sanding accessories on a 1/4 in. collet. Going cordless eliminates the hoses and compressor a pneumatic die grinder requires, and combined with the extended reach, this makes the tool especially well suited to service, fabrication, and repair work in awkward locations.
Control and ease of use carry over from the M12 FUEL die grinder platform. A 4-mode RPM speed control paired with a responsive variable-speed paddle lets the operator match speed to the application, from fine detail work up to aggressive material removal, which matters even more at the end of a long extension where control is key. An improved ergonomic handle enhances grip and comfort and reduces fatigue during extended use, and a shadowless LED work light maximizes visibility and accuracy in the low-light areas this tool is built to reach. A push-button spindle lock allows fast one-wrench accessory changes to keep downtime low between wheels and burrs.
As part of the Milwaukee M12 system of over 250 tools, the 3487-20 runs on any M12 REDLITHIUM battery and performs best with an M12 REDLITHIUM HIGH OUTPUT battery for maximum power and runtime. At 14.7 in. in overall length and just 1.9 lbs, it stays manageable despite the added reach. 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. For technicians already on the M12 platform who regularly fight for access in deep or confined spaces, the extended die grinder delivers the reach a straight-body grinder cannot, without giving up cordless portability.
