sharpen twist drill bits
I watched some youtube videos on drill bit sharpening. they all recommended a device such as this. This particular item also has extra features including center finder and picture diagrams and tables on the back. It was n't the cheapest on ebay but I think it was very good value. it will pay for its self may times over.
