Value Collection 01108794 Drill Blank Size 79 Hss

Product Description

The VALUE COLLECTION 01108794 is a wire gauge size 79 drill blank made from high speed steel with a bright, uncoated finish. Drill blanks are ground, unfluted rods used as starting stock for custom tooling, gauge pins, punch blanks, and similar precision machined components. At 0.0145 inch decimal diameter and 0.75 inches overall length, this blank is suited for fine-detail work where a standard twist drill would be impractical. Machinists and tool-and-die professionals grind these blanks to the exact geometry required for the application. The bright finish indicates no additional surface treatment, giving a consistent, measurable baseline diameter for close-tolerance work.

This drill blank is used in machine shops, toolrooms, and maintenance environments where custom tooling or gauge pins in the small-diameter range are needed. The wire gauge 79 size at 0.0145 inch diameter places it in the micro-drilling and fine-pitch tooling category. Applications include use as a gauge pin, pilot blank, scribe point, or starting stock for a custom-ground cutting tool. Machinists working on precision components, watch repair, instrument manufacturing, or electronics assembly fixtures commonly reach for blanks in this size range.

Key Features

• Wire gauge size 79 with 0.0145 inch decimal diameter for fine-tolerance applications
• High speed steel construction provides hardness and wear resistance suitable for grinding and toolmaking
• Bright uncoated finish gives a clean, consistent baseline diameter with no coating buildup
• 0.75 inch overall length is compact and suited for short-reach tooling applications
• Sold individually, allowing single-piece procurement for toolroom and maintenance use

Compatibility

Designed as a general-purpose high speed steel drill blank for use in toolrooms, machine shops, and maintenance operations requiring wire gauge size 79 stock.

Installation Notes

Drill blanks are raw stock and require grinding to a finished tool geometry before use in a spindle or holder. Handle with care during grinding operations, as the small diameter makes the blank susceptible to breakage under uneven lateral load. Use appropriate personal protective equipment when grinding high speed steel. Store blanks in a dry environment to prevent surface oxidation that could affect measured diameter.
