Value Collection 63323059 Drill Blank Letter a Hss

Product Description

The VALUE COLLECTION 63323059 is a letter-size drill blank ground to a Letter A diameter of 0.2340 inches with an overall length of 3.875 inches. Drill blanks are precision-ground, unfluted rods of high speed steel used as the raw stock for custom tooling, gauge pins, punch blanks, and specialty cutting tools. The bright, uncoated finish maintains close dimensional tolerances right out of the box. Machinists, tool-and-die makers, and toolroom technicians reach for drill blanks when fabricating or regrinding tooling to exact size requirements.

This blank is suited for toolroom and production environments where a Letter A diameter is required. Common applications include use as a ground stock reference, a punch or broach blank, a custom drill blank to be fluted and relieved in-house, or a plug gauge. The high speed steel construction handles the heat generated during secondary grinding and machining operations without losing temper at typical toolroom cutting speeds.

Key Features

• Letter A size corresponds to 0.2340 inch decimal diameter for precise dimensional reference
• High speed steel construction resists heat and wear during secondary tooling operations
• Bright, uncoated finish preserves as-ground surface dimensions without coating buildup
• 3.875 inch overall length provides sufficient stock for most punch, gauge, and drill fabrication applications
• Unfluted rod form allows regrinding or custom profiling to application-specific geometry

Compatibility

Designed as a general-purpose letter-size drill blank for toolroom fabrication, gauge work, and custom cutting tool production where a Letter A diameter of 0.2340 inches is specified.

Installation Notes

Drill blanks are raw stock and require secondary operations such as fluting, pointing, or relief grinding before use as a cutting tool. Secure workpieces properly in a tool-and-die vise or fixture before any grinding or machining operation. Use appropriate personal protective equipment, including eye protection, when grinding high speed steel. Follow shop safety procedures and equipment manufacturer guidelines for all secondary tooling operations.
