Can I sharpen some very long wood drill bits 18" x 7/8" diameter. These are typically used by plumbers and electricians. My neighbor has like 20 dull ones and wants to know if I can sharpen them for him. These drill bits are used for drilling through 3"headers and or rim joists and or thick glulam's. These typically have a lead screw tip on them. Can these be sharpened via the TormeK T-8?
