Supplied in the annealed state with a finely ground and polished surface. Its high accuracy to size, uniform properties that are free from defects and decarburization, opens a wide field of applications foe these drillrods.

Typical applications

Drills, taps, dies, arbors, balance staffs, cutting-off tools, chasers, engravers tools, jewelers tools, gauges, machinery parts, milling tools, pins, punches, pinions, pivots, roller bearings, threading dies etc.; also for guide rods and adjusting pins in tool manufacturing and general engineering, ejecting mandrels, surgical instruments, axis and shafts in precision mechanics.
