Drill Rod rounds are tough, free machining general purpose tool steels. They are used for punches, tools and dies, drills, taps, arbors, roller bearings, dowel pins and a variety of machine parts where high strength and long life are required.
Drill Rod rounds are annealed and ground and polished to a surface finish better than 30 microinches. The excellent finish, strength and machinability makes drill rod ideally suited for power drive shafts and applications where accuracy and straightness are required.
Drill Rod rounds are available from stock in 3 foot lengths in a wide range of diameters, in Water Hardening (W-1), Oil Hardening (O-1), Air Hardening (A-2 & D-2), High Speed Steel (M-2) and Shock Proof Air Hardening (S-7) grades and Hot Work Air Hardening (H-13) available Annealed and Pre-Hardened.
D-2 AIR HARDENING
This air hardening die steel offers significantly better wear resistance
and a high compressive strength that makes it a better choice than A-2
for long-run applications. It exhibits minimum distortion after heat treating. Though not as tough as the O-1 and A-2 grades, D-2 can withstand a surprising amount of shock and is widely used for difficult cold-forming
applications. This grade is an outstanding performer where high
production and/or close tolerance on finished parts are required.
