My dad has always sharpened his own, so I tend to do the same. In my experience, if used in wood they can be sharpened with little issue. If you drill through metal, buy a new one.
It loses some of the hardness on the edge. It really needs to be tempered again after sharpening. ----- Original Message ----- From: Rory Conaway To: af@afmug.com Sent: Wednesday, June 03, 2015 5:18 PM Subject: [AFMUG] Sharpening Drill Bits We are paying $15-$25 for longer drill bits. When they start to get dull, just wondering if anyone has had success sharpening them or do you just buy new ones? Rory Conaway . Triad Wireless . CEO 4226 S. 37th Street . Phoenix .
