Ideal drill bits for DBS-22

[wallbc]

For general drilling of wood, regular steel and aluminum what type of drill bit would be best for sharpening with the DBS-22?  I am assuming that with any of the cobalt and titanium coated bits the coating would be removed on the initial shaping of the four facets?  I don't really want to spend $1000+ for a set of solid carbide bits and I fear they would be very difficult to sharpen. So is a set of plain HSS twist bits my best option?  Also can you buy bits off the shelf that are already four faceted?

Welcome to the forum, Wallbc. My standard go to reference for drill bits is Leonard Lee's Sharpening book. Leonard Lee, now deceased, was the founder of Lee Valley tools. I have long recommended his Sharpening book as part of the standard part of every sharpener's home library. His advice is to acquire a set of quality US made standard hss bits. Here is a link:

I have dealt with Lee Valley for many years and have always found them honest and dependable with excellent service. They also have locations in many countries. The standard set should serve your needs.
