Value Collection 01100163 Drill Blank Letter E Hss

Product Description

The VALUE COLLECTION 01100163 is a letter-size drill blank ground to a 0.2500 inch (Letter E, 1/4 inch fractional) diameter and finished bright with no coating. At 4 inches overall length, this high speed steel blank serves as raw stock for custom tooling — machinists and tool-and-die shops grind these to finished drill geometry, reamers, or specialty cutting profiles. High speed steel construction provides the hardness and heat resistance needed for general-purpose metal cutting applications. The bright, uncoated finish leaves the surface ready for secondary grinding or custom edge preparation without additional stripping.

Drill blanks are used in machine shops, maintenance departments, and toolrooms where standard off-the-shelf cutting tools do not match the required geometry or diameter. This blank is suited for applications in ferrous and non-ferrous metals where a 0.2500 inch diameter tool profile is needed. It is commonly ordered by machinists, tool grinders, and skilled trades personnel who manufacture or recondition cutting tools in-house.

Compatibility

Designed as a general-purpose drill blank for use in machine shops and toolrooms requiring a 0.2500 inch diameter high speed steel blank at 4 inches overall length.

Installation Notes

Drill blanks require secondary grinding by a qualified machinist or tool grinder before use as a cutting tool. Secure the blank in an appropriate tool-holding fixture before grinding. Follow shop safety protocols including eye protection and proper wheel guards when performing surface or cylindrical grinding operations. Do not attempt to use an unground blank as a cutting tool.
