Value Collection 01100288 Drill Blank 7/16 in Hss

Product Description

The VALUE COLLECTION 01100288 is a high speed steel drill blank measuring 7/16 inch in diameter with a 5-1/2 inch overall length. Drill blanks are unfluted, precision-ground rods used as raw stock for custom tooling fabrication, reamer blanks, punch blanks, and specialty cutting tool production. This blank ships with a bright, uncoated finish, preserving the base HSS material properties. Machinists and tool-and-die professionals rely on HSS blanks when standard catalog tooling does not meet a job-specific geometry requirement. The uncoated surface allows for straightforward regrinding, EDM work, or secondary coating application.

This drill blank is suited for machine shops, toolrooms, and industrial maintenance environments where custom cutting tools or precision gauging components are fabricated in-house. Typical applications include grinding special-profile reamers, producing form tools, or creating hard gauges. The 7/16 inch diameter and 5-1/2 inch length make this blank appropriate for medium-scale tooling work on manual or CNC tool grinders.

Key Features

• High speed steel construction provides hardness and wear resistance suitable for tooling fabrication
• Bright, uncoated finish allows secondary grinding, coating, or EDM processing without stripping an existing surface treatment
• 0.4375 inch (7/16 inch) diameter for medium-range custom tooling applications
• 5-1/2 inch overall length provides adequate stock for grinding to final tool geometry
• Sold individually, allowing single-piece procurement for prototype or low-volume tooling runs

Compatibility

Designed as a general-purpose HSS drill blank for toolroom and machine shop use where custom-ground tooling is required. No specific equipment compatibility is defined for this product type.

Installation Notes

Drill blanks are raw stock and require machining or grinding before use as a finished tool. Fabrication should be performed by qualified machinists or tool grinders using appropriate wheel dress and coolant practices. Secure the blank firmly in the grinding fixture before beginning any stock removal. Inspect the finished tool for correct geometry and hardness before placing it into service.
