We carry Tool Steel Drill Rod in: A2 | D2 | H13 | M2 | O1 | S7 and W1. Tool steel drill rod is ground and polished to a surface finish of 16 Ra and 100% free of decarburization. All ends of drill rod in 3/8" diameter through 3" are saw-cut and chamfered or deburred, while the smaller diameters are precisely cut on automatic die-cutters to produce a clean end cut.
