Used them on live oak, hickory, cedar and mesquite. Works great without a tool, push the locking button to lock the shaft. Very cheap way to get started in power carving or to try it out.

Great product, better than expected. Would purchase again and would recommend them. Good quality for price, very pleased.

These sanding bits are very flimsy and cheap. The tips of these burrs have only a scattering of diamond particles. Didn't work at all in sanding.

I hate getting products that don't look like the item pictured. Ya get what ya pay for with these. Disappointed in the fact that i cannot use this set for it's intended purpose of lapidary work.
