This drill bit sharpener works very well. It was pretty easy to use and did an amazing job at sharpening my drill bits. It is made out of very durable materials and it should last a pretty long time. I would definitely recommend this drill attachment bit sharpener for anyone who uses their drill bits frequently and needs to reach sharpen them off in in order to keep them cutting smoothly and quickly. Great tool!

This is pretty neat. I got this because my husband is always gripping about his bit getting dull over time. He has his own automotive shop so he using his bits daily. And if they don't cut through the pipe without hesitation then he is wasting his time. He was excited when I showed him this sharpener. He used it right then. He attached his drill to the bit sharpener and started playing. It works great and he likes his new toy.

This is a perfect device. I used to drill on steel but then would have to throw away the bits because they got dull right away. Now I can just re-sharpen them and use them over and over again!! A great tool to have. Great gift too!!
