Value Collection 63323174 Drill Blank Letter N Hss

Product Description

The VALUE COLLECTION 63323174 is a letter N drill blank made from high speed steel with a bright, uncoated finish. Drill blanks are precision-ground cylindrical rods used as raw stock for fabricating custom drill bits, reamers, punches, and other cutting or gauging tools. This blank measures 0.3020 inches in diameter and 4-3/8 inches in overall length, providing consistent material for toolmakers and machinists who grind their own tooling to exacting specifications. The high speed steel construction delivers the hardness and heat resistance needed for reliable performance in demanding shop environments.

This drill blank is suited for machine shops, tool and die operations, and maintenance facilities where custom tooling is routinely fabricated. It is appropriate for use in both light industrial and heavy shop settings. Toolmakers grind the blank to the desired geometry for drilling, reaming, or specialty punching applications. The letter N designation corresponds to a 0.3020-inch decimal diameter, a common size in standard letter-series tooling sequences.

Key Features

• Letter N size with a 0.3020-inch decimal equivalent diameter
• 4-3/8 inch overall length provides adequate stock for grinding and tool shaping
• High speed steel construction resists heat buildup during cutting operations
• Bright, uncoated finish allows direct inspection of the base material surface
• Sold individually, making it practical for single-tool fabrication or replacement stock

Compatibility

Designed as a standard letter N drill blank for use in toolmaking, tool-and-die, and general machining applications where a 0.3020-inch diameter high speed steel blank is required.

Installation Notes

Drill blank grinding and shaping should be performed by qualified toolmakers or machinists using appropriate tool grinding equipment. Secure the workpiece properly before any grinding or cutting operation. Follow shop safety protocols including eye protection and proper guarding when working with grinding machinery. Finished tools should be inspected for correct geometry and surface finish before use in production.
