Here are a couple of definitions for drill blanks: Drill Blanks are short lengths of hardened high-speed steel used for making drills. Drill blank production High Speed Steel wire received on spools is processed at a critical atmospheric controlled temperature for straightening and hardening. The wire is then cut to stock lengths and drawn for several hours. Draw temperature and time differentials will produce specified hardness and temper characteristics. After being drawn, the stock lengths are cut down into rough drill blanks. Centerless equipment is used to grind the rough drill blanks down to a specified diameter, and RMS surface finish. The normal tolerance on the outside diameter is +0/-.0002 after this production phase. |
