LZ-4041 High-Speed Pneumatic Die Grinder - 22000 RPM Air Tool for Metalworking and Polishing

So you've got a shop floor where someone's spending hours blending welds on stainles steel handrails, and they need something that won't vibrate their hands numb by lunch—this little die grinder spins up to 22000 RPM, which is plenty for those precision passes without the tool walking all over teh workpiece.

We've been shipping these for a few years now, and what it does is handle continuous use better than a lot of the cheaper alternatives that start chattering after 20 minutes, mostly because aluminum alloy body keeps the weight down to 0.51 kg and the rear exhaust blows debris away form your hands rather than into your face.

The collet takes standard 1/4" bits, so you're not locked into proprietary accessories, and the ergonomic rubber grip actually makes a difference when you're maneuvering around tight corners—most buyers who switch from the plastic-handled ones notice it right away.

Air consumption is roughly 5 L/min at 90 PSI, which is efficient enough that you can run it off a smaller compressor without starving other tools on the same line, though we usually recommend a 3/8" hose to avoid pressure drop over longer runs (20 feet or so).

It's not built for heavy-duty stock removal like a 7-inch angle grinder would handle, but for deburring edges or polishing small parts, the vibration level stays under 2.5 m/s² and noise stays below 85 dB, which basically means your operators won't need double hearing protection during a full shift.

CE certified from TUV SOD, manufacturing defects, and we pack 25 pieces per carton for the bare tool or 20 kits per carton if you need the collet wrench and spare stones included—lead time is usually 2-3 weeks but check before ordering large quantities.
