Value Collection 63323117 Drill Blank Letter H Hss

Product Description

The VALUE COLLECTION 63323117 is a letter H drill blank ground from high speed steel with a bright, uncoated finish. Drill blanks are precision-ground cylindrical rods used as starting stock for custom cutting tools, punch pins, gauges, and specialty drill bits. At 0.2660 inches in diameter and 4.125 inches overall length, this blank gives toolmakers and machinists the material needed to grind, sharpen, or profile to a specific cutting geometry. The uncoated bright finish allows for straightforward inspection of surface condition and simplifies regrinding or secondary machining operations.

Letter H drill blanks are a standard tool room staple found in machine shops, maintenance departments, and tooling cells. This size is commonly used when fabricating custom drills, reamers, punches, or gauges to match a specific hole tolerance. The 0.2660 inch diameter corresponds to the ANSI letter drill series and is used across general metalworking, aerospace, automotive, and industrial maintenance applications. Machinists and tool grinders working in shops that hold their own tooling inventory will keep blanks like this on hand to reduce downtime when standard drill profiles are unavailable or a non-standard geometry is required.

Key Features

• Letter H size: 0.2660 inch decimal equivalent for precise tool room sizing
• High speed steel construction resists heat and wear during grinding and use
• Bright, uncoated finish for easy inspection and secondary processing
• 4.125 inch overall length provides stock for standard and extended-reach tool profiles
• Cylindrical blank form suitable for custom drill, punch, gauge, or reamer fabrication

Compatibility

Designed as a standard letter H drill blank suitable for general tool room and machine shop applications where a 0.2660 inch diameter high speed steel blank is required.

Installation Notes

Drill blanks are raw stock and require grinding or machining before use as a finished cutting tool. A qualified machinist or tool grinder should perform all shaping, pointing, and finishing operations using appropriate grinding equipment. Inspect the blank for surface defects before machining. Follow shop safety protocols for grinding operations, including eye protection and proper wheel guards.
