Proxxon28941 Hand Tools Supplies & Accessories

Good product but over priced

I've had my Harbor Freight Chicago Electric 35,000 RPM Variable Speed Rotary Tool for over a decade and have been mostly happy with it. Always hated the poor quality stock chuck which forced me to use a wrench/tool to fully tighten and remove the bits. Over time, the jaws deformed and the bits would wobble dangerously at moderate to high tool speeds. It got to the point where I started avoiding the tool.Then I decided to try my luck with this tool free chuck from Proxxon. Now my HF Rotary Tool is better than ever and I have zero fears about using it at high speed. The bits stay perfectly centered and get a positive mount every single time using just fingers and the stock yellow lock tab. Very minimal, almost non existent wobble throughout the whole speed range with all my attachments and bits.Very happy with this mod/repair and will absolutely recommend it to anyone.Minimal mods required, I don't recall fully but I think all I had to do was chop down the original circular plastic trim piece with a hacksaw blade to clear the deeper mounting base on the new chuck. I suppose you could use the tool without the trim ring, but I prefer to keep it on. See my detailed pics.

Qualità prezzo eccellente

Aber Achtung,.. passt nur auf die angegebenen Maschinen. Und das sind leider nur wenige. Es gibt auch zwei verschiedenen Biegsame Wellen. Die mit dem BF hat eine kürzere Überwurfmutter. Passt leider nicht auf den IBS/E. Der angepriesene Vorteil von Spannzangen ggü. dem Bohrfutter, bzgl. Rundlauf kann ich nicht bestätigen.Die laufen beide absolut rund.
