Hello out there, I am the Director of Marketing for Drill Doctor. Iam happy to see that so many people are getting good results using the Drill Doctor. For anyone having any trouble, please get in touch with us. Our Tech Support staff here in Oregon are eager to resolve any issues you might have. Furthermore, we are just a small family owned business so we will stand behind our products if something is wrong with them.

That being said, Aerofly, you asked about sharpening Spade Bits. As a matter of fact we just launched a new model Drill Doctor which can sharpen both twist and spade bits, here is a link to our site where you can check it out:
