Value Collection 01108422 Drill Blank Size 42 Hss

Product Description

The VALUE COLLECTION 01108422 is a wire gauge size 42 drill blank machined from high speed steel with a bright, uncoated finish. At 2.25 inches overall length and 0.0935 inches in decimal diameter, this blank is a semi-finished cutting tool blank used by machinists and tool grinders to produce custom drill points or to regrind worn tooling to specification. High speed steel construction provides the hardness and thermal resistance needed for general-purpose drilling across a broad range of workpiece materials. The bright finish means no coating has been applied, leaving the steel surface in its natural ground state for direct use or further finishing.

Wire gauge drill blanks in size 42 are commonly used in precision machining environments, toolrooms, and production shops where small-diameter hole making or custom tool fabrication is required. This blank is suited for use in drill presses, lathes, and CNC equipment where the operator or tool grinder will finish the cutting geometry. Typical applications include creating pilot holes, producing small-diameter through-holes in metal, plastic, and composite materials, and restoring worn drill geometry on the shop floor.

Key Features

• Wire gauge size 42 with a decimal diameter of 0.0935 inches for precise small-bore applications
• High speed steel construction resists heat buildup during cutting and grinding operations
• Bright, uncoated finish allows direct use or custom surface treatment after purchase
• 2.25 inch overall length provides sufficient stock for grinding a working cutting edge
• Consistent blank geometry supports repeatable regrinding and tool reconditioning

Compatibility

Designed as a standard wire gauge size 42 drill blank for use in toolrooms and machining operations requiring a 0.0935 inch diameter high speed steel blank.

Installation Notes

Drill blank preparation and grinding should be performed by a qualified machinist or tool grinder using appropriate wheel dressing and coolant practices. Secure the blank firmly in the grinding fixture before shaping the cutting geometry. Eye protection and grinding guards must be in place during all grinding operations per applicable shop safety standards. Inspect the finished cutting edge for correct geometry before use in any drilling application.
