I'm getting set to purchase two sets of drill bits - fractional (1/16" to 1/2" in 64ths) and number (#1 to #60). I'd like to acquire some higher-quality sets, so I'm thinking Cleveland or Hertel. I guess I'll get them from MSC, I have an account there - but I've ordered from McMaster-Carr and Enco before so who knows. I'm just a home hobbyist, so I want to get my money's worth - I can't afford to own several sets.
I think I'm fairly clear on point angles (135-degrees will "walk" less on hard surfaces), and I'm definitely looking for screw-machine length instead of the jobbers-length. But I'm confused about the point styles that are out there...split point, chisel point. There are probably others that I don't know about.
I drill a fair amount of wood, but I drill metals too. Brass, steel & aluminum. I use an inexpensive Delta tabletop drill press, but it's in great shape and seems to do a good job.
Can someone explain the differences in the tip geometries out there with drill bits? Maybe there's a good primer I should purchase and read.
Thanks in advance,
Doug
