Value Collection 01100478 Drill Blank 47/64 in Hss

Product Description

The VALUE COLLECTION 01100478 is a high speed steel drill blank ground to a 47/64 inch (0.7344 inch decimal) diameter with a 6 inch overall length. Drill blanks are unfluted, precision-ground cylindrical rods used as the raw stock for custom cutting tool fabrication, gauging, and fixture work. The bright/uncoated finish maintains tight dimensional tolerances right out of the package. Machinists and tool-and-die tradespeople reach for blanks like this when grinding custom drill geometries, making punches, or checking bore sizes. At 0.2 pounds, the blank is easy to handle at the bench or surface grinder.

This drill blank suits machine shops, toolrooms, and industrial maintenance environments where off-the-shelf drill geometries do not meet the job. It is a single-piece stock item appropriate for one-off custom tool grinding or small-batch production setups. The high speed steel construction holds up to the heat generated during grinding and regrinding operations, making it a reliable choice for shops that prefer to finish-grind their own cutting tools in-house.

Key Features

• 47/64 inch (0.7344 inch decimal) diameter for precise fitment in standard collets and tool holders
• 6 inch overall length provides ample stock for grinding custom flute profiles or step geometries
• High speed steel construction resists heat buildup during grinding and cutting operations
• Bright/uncoated finish ensures dimensional accuracy without coating-thickness variation
• Lightweight at 0.2 pounds for easy bench and grinder handling

Compatibility

Designed as a general-purpose drill blank for use in custom tool grinding, gauging, and fixture applications requiring a 47/64 inch diameter high speed steel blank with a 6 inch overall length.

Installation Notes

Drill blanks are finished by machinists or tool grinders and are not drop-in replacements for finished cutting tools. Secure the blank properly in a tool-and-cutter grinder or surface grinder with appropriate wheel dressing before grinding operations begin. Wear eye protection and follow shop safety protocols when grinding high speed steel. Inspect the finished tool geometry before placing it into service on any machine.
