Value Collection 01100098 Drill Blank 9/64 in Hss

Product Description

The VALUE COLLECTION 01100098 is a high speed steel drill blank sized at 9/64 inch (0.1406 inch decimal) diameter with an overall length of 2-7/8 inches. Drill blanks are unfluted, precision-ground cylindrical rods used as raw stock for fabricating custom cutting tools, punches, gauges, and special-purpose drills. The bright, uncoated finish preserves the base HSS material for downstream grinding, EDM, or tool-and-die work. Diameter tolerance is held to +0.0000 to -0.0003 inch, making this blank suitable for close-tolerance tooling applications. Machinists, tool grinders, and die makers are the primary users in shop and manufacturing environments.

This drill blank is suited for tool room and production shop applications where a standard off-the-shelf drill geometry does not meet the required specification. It serves as raw material for grinding custom step drills, pilot tools, punches, and gauges. The tight diameter tolerance supports precision fitment in jigs, fixtures, and hardened die sets. Typical use cases include prototype tooling, replacement of worn or broken special-purpose drills, and short-run custom cutter fabrication.

Key Features

• 9/64 inch (0.1406 inch) diameter with a tight tolerance of +0.0000 to -0.0003 inch for close-tolerance tooling work
• 2-7/8 inch overall length provides adequate stock for grinding standard or custom tool geometries
• High speed steel construction offers good hardness and wear resistance for cutting tool applications
• Bright, uncoated finish is ready for surface grinding, EDM, or coating processes without additional prep
• Lightweight at 0.012 pounds per piece — easy to inventory in quantity

Compatibility

Designed as a general-purpose HSS drill blank for use in tool room, die shop, and production machining environments where a 9/64 inch diameter round blank is required as raw stock.

Installation Notes

Drill blanks require grinding or EDM operations by a qualified tool grinder or machinist before use as a cutting tool. Secure the blank properly in a tool and cutter grinder or surface grinder fixture before applying any geometry. Inspect the finished tool for concentricity and edge condition before use in a spindle. Follow applicable shop safety standards for grinding operations, including the use of eye protection and proper wheel guards.
