Value Collection 01100429 Drill Blank 21/32 in Hss

Product Description

The VALUE COLLECTION 01100429 is a high speed steel drill blank sized at 21/32 inches (0.6562 inches decimal) in diameter with a 6 inch overall length. Drill blanks are unfluted cylindrical rods ground to precise tolerances, used as raw stock for custom cutting tool fabrication, gauge pins, punch tooling, and specialty boring applications. This blank carries a bright uncoated finish, leaving the base high speed steel exposed for applications where coating is unnecessary or where the end user will apply their own surface treatment. Machinists and tool-and-die professionals are the primary users of this type of stock.

This drill blank suits machine shops, tool rooms, and fabrication environments where standard off-the-shelf drill geometry does not meet the job. It is commonly ground or formed into custom reamers, D-bit cutters, stepped tools, or used as locating pins and transfer punches. The 6 inch OAL provides sufficient length for most bench grinding and tool room lathe operations. At 0.2 pounds, it handles easily on a surface grinder or tool post grinder setup without requiring special fixturing for basic profiling work.

Key Features

• 21/32 inch (0.6562 inches decimal) diameter ground to close tolerance for reliable fitment and accurate custom tooling
• 6 inch overall length provides working stock for a wide range of tool room grinding and forming operations
• High speed steel construction offers hardness and wear resistance suitable for cutting tool fabrication
• Bright uncoated finish allows direct use or post-fabrication coating by the end user
• Lightweight at 0.2 pounds for easy handling during bench and surface grinder work

Compatibility

Designed as a general-purpose tool room blank compatible with standard surface grinders, tool post grinders, and bench grinders used in machining and fabrication environments where a 21/32 inch diameter high speed steel blank is required.

Installation Notes

Drill blanks are raw stock and require machining or grinding by a qualified machinist before use as a finished cutting tool or locating component. Secure workholding is essential during all grinding operations to prevent blank ejection or surface damage. Always wear appropriate PPE including eye protection when grinding high speed steel. Follow applicable shop safety procedures and equipment manufacturer guidelines during all fabrication work.
