bk size for sale, brand-new and used.

Designed to sharpen drill bits in the 3/4" to 2 1/2" size range (up to 21 3/4" long), it will pay for itself in a matter of months even if you only need to sharpen one or two drill bits a week. A drill bit sharpened on the BK65 will be restored to at least the cutting accuracy of a brand new drill bit, and the curved geometric grind with radial relief will most likely provide performance that surpasses a new drill bit.
