Value Collection 63323125 Drill Blank Letter I Hss

Product Description

The VALUE COLLECTION 63323125 is a letter-size drill blank in size I, ground to a decimal diameter of 0.2717 inches with an overall length of 4.125 inches. Drill blanks are unfluted, precision-ground rods used as the starting stock for custom cutting tools, reamer blanks, gauges, and punch pins. Made from high speed steel with a bright, uncoated finish, this blank retains hardness at elevated temperatures and holds tight dimensional tolerances. Machinists, tool-and-die makers, and production shops use drill blanks when standard off-the-shelf tooling does not meet a specific diameter or geometry requirement.

This blank is suited for use in tool-and-die shops, maintenance and repair operations, and precision machining environments. It serves as raw material for fabricating custom drills, reamers, and gauges, or as a gauge pin in inspection and layout work. The letter I designation and 0.2717-inch diameter make it useful anywhere a close-tolerance cylindrical blank of that size is needed. The bright finish means no coating removal is required before grinding or further machining.

Key Features

• Letter I size with a decimal diameter of 0.2717 inches for precise tooling applications
• Overall length of 4.125 inches provides ample stock for custom tool fabrication
• High speed steel construction maintains hardness under heat generated during machining
• Bright, uncoated finish allows immediate use as a gauge pin or direct grinding without stripping
• Single-piece packaging suits one-off tooling and repair jobs

Compatibility

Designed as a general-purpose drill blank for use in tool-and-die, inspection, and precision machining applications requiring a letter I diameter cylindrical blank in high speed steel.

Installation Notes

Drill blanks are raw stock and require machining or grinding before use as finished cutting tools. Machinists and tool grinders should use appropriate wheel speeds and coolant when grinding high speed steel to prevent overheating and loss of temper. Secure the blank firmly in the appropriate fixture or chuck before any machining operation. Follow shop-standard personal protective equipment and machine guarding practices when working with rotating equipment.
