Value Collection 01100171 Drill Blank 17/64 in Hss

Product Description

The VALUE COLLECTION 01100171 is a high speed steel drill blank ground to a 17/64 inch (0.2656 inch decimal) diameter with an overall length of 4-1/8 inches. Drill blanks are unfluted, precision-ground cylindrical rods used as raw stock for custom tooling fabrication, gauge pins, punch blanks, and specialty cutting tools. The bright, uncoated finish preserves the base HSS material properties and keeps the surface ready for further grinding or coating operations. Machinists, tool grinders, and toolroom technicians are the primary users of this stock.

This drill blank is suited for toolroom and job shop environments where standard off-the-shelf tooling does not meet a specific diameter, geometry, or application requirement. It serves as raw material for single-point tools, step drills, reamers, and form tools ground to custom specifications. The 4-1/8 inch overall length provides sufficient stock for most standard tooling configurations at this diameter range.

Key Features

• 17/64 inch (0.2656 inch decimal) diameter for precise fitment in toolroom applications
• 4-1/8 inch overall length provides adequate stock for custom ground tooling
• High speed steel construction offers good wear resistance and toughness for cutting tool fabrication
• Bright, uncoated finish leaves surface ready for secondary grinding, coating, or heat treatment
• Unfluted cylindrical form allows full-diameter stock removal during custom geometry grinding

Compatibility

Designed as a general-purpose drill blank for toolroom fabrication of custom cutting tools, gauges, and punch blanks requiring a 17/64 inch diameter high speed steel blank.

Installation Notes

Drill blanks are raw tooling stock and require secondary operations by a qualified toolroom machinist or tool grinder before use as a finished cutting tool. Secure work properly in a tool and cutter grinder or surface grinder before any grinding operations. Follow standard shop safety practices including eye protection and proper grinding wheel guards. Verify finished tool geometry against applicable print or specification before placing the ground tool into service.
