FAQ:

1. What is a drill rod?

A drill rod is a form of bar stock machined to produce tools such as drill bits, taps, dowel pins, shafts, reamers, files, punches and hammers. It's soft enough to shape but can be heated up to revert back to the hardness. Drill rods are manufactured from tool steel that has been ground to a tight tolerance diameter.

2. What type of steel is drill rod made of?

annealed tool steel

Drill rod is made of annealed tool steel with a Rockwell hardness ranging from 96 to 110 rb. It is typically soft enough that it can be easily machined, although it is hard enough to use in some applications without heat treatment.

3. How are drill rods made?

Drill rods are manufactured by cutting a pin and a box thread directly onto the steel tube – the drill rod is therefore a one-piece construction. All standard wireline drill rod is manufactured in this way.

4. How do you harden a hardening drill rod?

HEAT TREATMENT Sections smaller than ¼” heat to 1450°-1475°F and hold until heated through. For larger sections, preheat to 1200°F, the raise to 1450°-1500°F to hardening temperature, hold one-half hour per inch of cross section. Quench in oil at 125°-150°F and TEMPER IMMEDIATELY.
