Re: Drill Rod

 

Mike,
Drill is not the same as cold rolled steel. Drill rod is a high carbon steel capable of being hardened by heat treating. It usually is available in three foot lengths and is designated as O-1 (oil hardening), W-1 (water hardening) and also air hardening. Drill rod is centerless ground close to the designated size and is readilly machined using standard high speed tooling.Drill blanks are usually made from High Speed steel, hardened and ground and too hard to machine with standard tooling.

Is drill rod just basically cold rolled steel that's made to better tolerances?

Is it easy to drill and tap like cold rolled steel is? It's not drill bit blanks to make drill bits from right?

Thanks!
