This is the most-used tool on my bench for shaping smaller pieces of wood. I have spent some time looking, and have never found a better burr. Kutzall products are excellent and I highly recommend them for your bench.

They cut wood like it is butter, clean up is super easy and they are as good as new. I and my business will be life-long customers.

This unit can strip material FAST! Practice with it first, before main project, and HOLD ON!!!
- VCVincent C. R.Verified BuyerRated 4 out of 5 stars1 month agoKeep a stiff wrist!
This sphere burr if awesome! In a die grinder it removes a lot of wood, but be carefull to keep a stiff wrist. Otherwise it will jump out and ruin the rim of the bowl or cup. With a little pratice, it will become a valueable addition to your arsenal of tools for carving. No other burr (that I know of) will remove so much wood as fast as the Kutzall Sphere Burr. Quality made.
- PBPaul B.Verified BuyerRated 5 out of 5 stars1 month agoThis removes the right amount of wood.
It is a great burr, 1/4 shaft is great, removed wood quickly. Very happy with my purchase.
