I've been a road engineer for about 30 years so I tried my hand at drills. I've tried everything from Harbor Freight (junk) to Snap On, Matco, Sears, MAC and pretty much everything in between. About five years ago I got hooked on these snippets of Norseman and I've never looked back. This is easily the best drill on the market. Drilling slowly and slowly (low speed, low to medium pressure on the bit) and using cutting fluid, these bits will bore through metal for years without the need for sharpening. This money is worth it.
