Value Collection 01100213 Drill Blank 21/64 in Hss

Product Description

The VALUE COLLECTION 01100213 is a high speed steel drill blank ground to a 21/64 inch (0.3281 inch decimal) diameter with an overall length of 4-5/8 inches. Drill blanks are unfluted, precision-ground cylindrical rods used as raw stock for custom tooling, gauge pins, punch blanks, and specialty drill fabrication. This blank ships in a bright, uncoated finish, leaving the steel surface ready for further grinding, coating, or heat treatment as the application demands. Machinists, tool-and-die makers, and maintenance technicians keep drill blanks on hand for custom tooling setups where standard off-the-shelf drills do not meet exact size or length requirements.

This blank is suited for tool room applications, maintenance shops, and production environments requiring a precise, consistent-diameter steel rod at a fractional inch size. Common uses include reaming out soft fixtures, fabricating custom step drills, producing gauge pins, and serving as a starting point for specialty cutting tools. The 4-5/8 inch overall length provides adequate stock for most light to medium tooling tasks without excessive waste during grinding operations.

Key Features

• 21/64 inch fractional diameter (0.3281 inch decimal) for precise, repeatable sizing
• 4-5/8 inch overall length provides sufficient stock for custom grinding and fabrication
• High speed steel construction offers good hardness and wear resistance for tooling applications
• Bright, uncoated finish leaves surface ready for secondary operations such as coating or heat treatment
• Unfluted cylindrical form supports use as gauge pins, punch blanks, or custom drill fabrication

Compatibility

Designed as a general-purpose tool room blank compatible with standard drill blank holders, collets, and grinding setups that accept 21/64 inch diameter stock.

Installation Notes

Drill blanks are handled and shaped by machinists or tool-and-die makers using precision surface grinders and tool room equipment. Secure the blank properly in the appropriate holding fixture before any grinding or machining operation. Wear appropriate personal protective equipment when grinding high speed steel. Follow shop safety procedures and equipment manufacturer guidelines during all secondary operations.
