Value Collection 01108315 Drill Blank Size 31 Hss

Product Description

The VALUE COLLECTION 01108315 is a wire gauge size 31 drill blank made from high speed steel with a bright, uncoated finish. Drill blanks are precision-ground cylindrical rods used as the starting stock for custom tooling, reamer blanks, punch blanks, and close-tolerance locating pins. At 0.1200 inch diameter and 2.75 inches overall length, this blank gives toolmakers and machinists a true, consistent starting diameter for grinding or finishing operations. High speed steel construction provides the hardness and wear resistance needed to hold dimensional accuracy through secondary machining processes.

This drill blank is suited for tool and die shops, machine shops, and maintenance departments that fabricate or refurbish cutting tools and fixtures in-house. The bright, uncoated surface is left in its ground state, making it ready for custom grinding, lapping, or case-hardening without a coating to remove first. Typical applications include use as a transfer punch blank, ejector pin substitute, or raw stock for specialized reamers in both production and repair environments.

Key Features

• Wire gauge size 31 corresponding to 0.1200 inch decimal diameter
• High speed steel construction for hardness and wear resistance
• Bright, uncoated finish provides a clean surface ready for secondary operations
• 2.75 inch overall length provides adequate stock for most blank tooling applications
• Consistent ground diameter supports close-tolerance fabrication work

Compatibility

Designed as a standard wire gauge size 31 drill blank for use as raw tooling stock in machine shop and tool and die applications where a 0.1200 inch diameter high speed steel blank is required.

Installation Notes

Drill blanks are handled and finished by machinists and toolmakers using surface grinders, lathes, and bench equipment. No power-down or lockout procedure is required for the blank itself, but all secondary machining operations should follow applicable shop safety practices and machine guarding requirements. Blanks should be inspected for dimensional accuracy prior to grinding to ensure the finished tool meets required tolerances. Store in a dry environment to prevent surface oxidation on the uncoated steel.
