I disagree on part of that. Good, and very good bits CAN be bought at Home Depot. The secret is u need to know which bits to choose. Select a name brand like Bosch, Rigid, Ryobi, or Dewalt. The Rigid cobalt bits at HD are excellent. EVERY off brand bit I have ever seen is JUNK! Bit condition is extremely important as well as technique. Keep them sharp, use cutting oil and drill at the correct speed for the bit size and material. Also, be sure to drill a small pilot hole first, then enlarge it slowly. I go at least 1/8, 3/16, 1/4, 5/16, 3/8, 7/16, 1/2...etc. I gotta tell u, handrilling a 1" hole in 1/4" steel can be a real battle hanging onto the drill
1. HSS black oxide bits are the slowest, cheapest and weakest but will work if used correctly.
2. Titanium oxide are the next step and a good compromise.
3. Cobalt are VERY good, but expensive.
Split point bits are great to control wander for the starter hole.
I have not figured out how the pilot point bits are supposed to work. I tried a couple and was unable to drill even one hole without the bit becoming a chewed up mess and spending way too much time on one hole. I stay way away from them...which pisses me off cuz they seem to be taking over the market.
HD sells a smaller BOSCH set of the titaniums from 1/16 - 1/2 for $30. It is a great value, gives a basic selection and they are quality. They also sell a Ryobi HSS set from 1/16 - 1/2 by 64ths which are EXCELLENT bits at a great price if u want HSS.
Ive been hand drilling a lot of stainless this yr. I buy the Rigid cobalt bits by the dozen which is the only bit to use in ss. Learning how to drill ss was a real education. The 1/8" pilot hole is the hardest, but now I can drill it rather quickly and get 2-300 holes before the bit dulls. When a cobalt bit is too dull to drill ss quickly, it is still sharper than the black oxide or titanium bits, so I just rotate them into that set.
I think u must be using dull bits Britt. Coyotekillr has drilled many frame holes to mount his hitch as well as his ft winch bumper. It only took him a few minutes/hole. If a rookie can get it done, u got no excuse  |
