Value Collection 01100379 Drill Blank 37/64 in Hss

Product Description

The VALUE COLLECTION 01100379 is a high speed steel drill blank measuring 37/64 inch (0.5781 inch decimal) in diameter with a 6 inch overall length. Drill blanks are unground, precision-diameter rods used as stock for custom tooling, reamer blanks, punch and die work, or specialty cutting tools ground to a specific geometry. This blank ships in a bright, uncoated finish, leaving the steel surface ready for grinding, coating, or other secondary operations. Machinists, tool-and-die makers, and production grinding shops are the primary users of this stock.

This drill blank is suited for tool room and production environments where a standard off-the-shelf drill geometry does not meet the application requirement. Common uses include grinding custom single-flute drills, step drills, reamers, and other rotary cutting tools from scratch. The bright finish makes layout lines and measurement marks easy to apply before grinding. At 6 inches in length, the blank provides enough stock for most single-tool grinding jobs with material left over for re-grinding or correction.

Compatibility

Designed as an OEM-style replacement or raw stock for custom rotary cutting tools ground from high speed steel drill blank material in standard fractional sizes.

Installation Notes

Drill blanks require secondary grinding to produce a finished cutting tool and should only be processed by qualified machinists or tool grinders using appropriate wheel speeds and coolant. Secure the blank firmly in a tool-and-cutter grinder or surface grinder fixture before any material removal. Inspect the blank for straightness and surface condition before grinding to avoid producing an out-of-tolerance tool. Follow shop safety standards for grinding operations, including eye protection and proper wheel guarding.
