Summary: great, set a side some time to figure it out. sharpens better than by any hand but not as good as factory sharp. i tried it many times. still saves you money for sure. champion bits are the best too
Summary: Works better than expected. I had used an older model of this product that wasn't great, but this is very much improved.We used to spend lots of time in front of a grinding wheel which requires a certain level of skill to re-sharpen our drill bits. This is quick and simple.
