Overview
Running on shop air rather than a battery or cord, this die grinder spins at 25000 RPM and weighs just 12.32 ounces, light enough for one handed detail work.
The brand and model fields here read more like a UPC number than a marketed brand name, which is common with lower cost pneumatic tools sold generically. What is clear from the spec sheet is the tool class: a high speed, air driven die grinder built for small bit work rather than heavy material removal. Buyers will need a compressor and air line, since it has no battery or cord option.
- Pneumatic (air) powered die grinder
- Spins at 25000 RPM
- Weighs 12.32 ounces
- Rated 4.3 stars across 302 reviews, 100 bought in the past month
Who it's for
Fits shops and garages that already run an air compressor and want a small die grinder for deburring, cleaning welds or light detail work. Not for anyone without an existing compressed air setup.
Strengths and trade-offs
Drawn from this product's published specifications.
- Very light at 12.32 ounces for one handed control
- 25000 RPM suits fast detail grinding
- Requires a compressor and air line to run
- Brand and model read as a part number, not a name
Performance notes
At 25000 RPM the tool is geared for speed over torque, which suits small burrs and mounted points rather than removing large amounts of material. Its 12.32 ounce weight keeps hand fatigue low during extended detail work, a common complaint with heavier grinders. Because it is pneumatic, output depends on the compressor supplying it, not on a motor winding or battery inside the tool itself.
