Value Collection 63323182 Drill Blank Letter O Hss

Product Description

The VALUE COLLECTION 63323182 is a letter O drill blank machined from high speed steel with a bright, uncoated finish. Drill blanks are ground, unfluted rods used as the raw stock for custom tooling, punch making, gauging, and fixture work in machine shops and toolrooms. This blank measures 0.316 inches in diameter and 4.5 inches in overall length, giving machinists and tool grinders sufficient stock to shape, grind, or modify into reamers, punches, custom drill bits, or other precision tools. The bright finish means no coating interferes with further surface grinding or polishing operations.

This drill blank is suited for toolroom, maintenance machining, and light manufacturing environments where a precise, hardened steel rod is needed as a starting point for fabrication. Common applications include creating custom single-point tools, go/no-go gauge pins, ejector pins, and hand-ground reamers. Machinists working with manual grinders or surface grinders will find this stock ready for immediate use in shaping operations.

Key Features

• Letter O size corresponds to 0.316 inches in diameter for precise fitment in standard drill blank sizing charts
• High speed steel construction provides hardness and wear resistance suitable for tool grinding applications
• Bright, uncoated finish leaves the surface ready for secondary grinding, lapping, or polishing
• 4.5-inch overall length provides adequate stock for most custom tooling and gauging tasks
• Single-piece packaging keeps inventory simple for low-volume toolroom procurement

Compatibility

Designed as a standard letter O drill blank for use in toolroom and machine shop applications requiring a 0.316-inch diameter high speed steel blank.

Installation Notes

Drill blanks are handled and shaped by machinists using bench grinders, surface grinders, or tool and cutter grinders. Ensure the grinding wheel is rated for high speed steel before beginning any material removal. Eye protection and appropriate grinding guards are required during shaping operations. Store blanks in a dry environment to prevent surface oxidation on the uncoated finish.
