It’s nice having a tool & die maker in the family, someone who can make a set of drill bits from scratch. I still have the tool & die maker, just not the equipment. Back in the 90’s when flying back home for a visit I’d sometimes bring a set of drill bits that needed sharpening. My dad and I would go to his shop and sharpen them. He’d usually do it with something like the #825 Drill Bit Grinding Attachment by general tool in the $40 price range, https://www.generaltools.com/drill-bit-grinding-attachment . A similar but more advanced tool is the “Tormek Drill Bit Sharpening Attachment” in the $300 price range. https://www.sharpeningsupplies.com/Tormek-Drill-Bit-Sharpening-Attachment-P406.aspx These allow the use of a bench grinder, a multipurpose tool which can be powered by pedals. There are stand alone drill bit sharpeners available for purchase. Under $200 the “Drill Doctor” has a line of them. https://www.northerntool.com/shop/t...s+sharpeners-accessories+drill-bit-sharpeners Anyone have preferences on sharpening drill bits? From a prepping point of view a way to sharpen drill bits would come in handy.
