Value Collection 01100148 Drill Blank 7/32 in Hss

Product Description

The VALUE COLLECTION 01100148 is a high speed steel drill blank measuring 7/32 inch (0.2188 inch decimal) in diameter with an overall length of 3-3/4 inches. Drill blanks are unground, precision-diameter rods used as starting stock for custom tooling fabrication, including specialty drills, punches, gauges, and locating pins. The bright, uncoated finish leaves the steel in its natural state, making it straightforward to grind, hone, or modify to a specific geometry. Machinists, tool-and-die makers, and toolroom technicians keep drill blanks on hand for low-volume custom tool production and repair work.

This blank is suited for toolroom and machine shop environments where off-the-shelf tooling does not meet a specific diameter or geometry requirement. The 7/32 inch diameter falls within a common fractional size range, making it a practical choice for fabricating replacement drills, step tools, or positioning pins in both light manufacturing and maintenance repair operations. It is appropriate for use in job shops, production toolrooms, and industrial maintenance departments.

Key Features

• High speed steel construction provides good hardness and wear resistance for custom tooling applications
• Bright, uncoated finish allows direct grinding or finishing without removing a coating layer
• Decimal diameter of 0.2188 inch offers precise sizing for close-tolerance tooling work
• 3-3/4 inch overall length provides sufficient stock for most standard drill or pin fabrication tasks
• Fractional 7/32 inch size aligns with common toolroom size series

Compatibility

Designed as a general-purpose drill blank for toolroom fabrication and custom tooling applications requiring a 7/32 inch diameter high speed steel rod.

Installation Notes

Drill blanks require grinding by a qualified toolmaker or machinist before use as cutting tools. Appropriate personal protective equipment, including eye protection, must be worn during all grinding operations. Secure the blank firmly in a tool grinder or surface grinder fixture before beginning any material removal. Follow applicable shop safety standards and equipment manufacturer guidelines when processing high speed steel stock.
