A2 Drill Rod

A2 Drill Rod, is an air hardening chromium alloy die steel that replaces O1 Drill Rod when safer hardening, less distortion and increased wear resistance are required. Characteristics of A2 Drill Rod include - good machinability, high compressive strength, very good non-deforming properties, deep hardening, and high dimensional stability after hardening and tempering. A2 Drill Rods are ground to a surface finish of better than 40 micro inches and are free from defects and decarburization. All Drill Rod grades are supplied in the annealed condition.
  • Specifications: ASTM A681, QQ-T-570, AISI A2
  • AKA: A-2 round, A-2 Drill Steel, Drill Rods
  • Applications: dies, stamps, punches, taps, cams, machine parts, etc.
  • Tolerances: Diameter = +/- .0005"
  • How is it Measured? Diameter (A)  X  Length
