High-Speed Pencil Die Grinder - 70,000 RPM Precision Rotary Tool for Metal Engraving, Wood Carving & DIY Crafts - Perfect for Jewelry Making, Automotive Detailing & Small Space Grinding

I used this tool for at least 4 days a week for at least a few months for several hours a day until i sold it to a coworker when i bought a Dynabrade turbine powered 100,000 rpm pencil grinder....which really sucked and had little to no torque whatsoever. so it was usless to me and I completely regret buying that expensive p.o.s.. I used the Sioux to put some heavy edge breaks on some very hard metal parts. So I put alot of pressure on this tool alot. For the most part it had a good amount of torque. The wedges on the inside of the pencil grinder eventually broke after a few months but that was after a whole lot of abusive work done with it and those wedges are very easily replaced and cheap. this pencil grinder works well with even titanium and inconel which are very hard metals
