Value Collection 01100403 Drill Blank 5/8 in Hss

Product Description

The VALUE COLLECTION 01100403 is a high speed steel drill blank measuring 0.6250 inches (5/8 inch fractional) in diameter with a 6-inch overall length. Drill blanks are precision-ground cylindrical rods used as raw stock for fabricating custom cutting tools, punches, gauges, and specialty drills. Machinists and tool-and-die professionals grind these blanks to the exact geometry required for a specific job. The bright, uncoated finish indicates no post-process coating has been applied, which is standard for blanks intended to be further machined or ground to final form.

This blank is suited for tool room environments, job shops, and maintenance departments where off-the-shelf cutting tools do not meet the required geometry or tolerance. It is appropriate for applications in metalworking, fabrication, and precision manufacturing. The high speed steel material retains hardness at elevated temperatures, making it a reliable choice for blanks that will be ground into drills, reamers, or form tools used in moderate-duty cutting operations.

Key Features

• 0.6250 inch (5/8 inch) diameter for consistent starting stock
• 6-inch overall length provides sufficient material for most custom tool fabrication tasks
• High speed steel construction retains edge hardness under heat generated during cutting
• Bright, uncoated finish is ready for grinding and finishing to final tool geometry
• Sold individually, suitable for single-tool fabrication or prototyping

Compatibility

Designed as standard-diameter drill blank stock for use in tool room and job shop applications requiring a 0.6250 inch diameter high speed steel blank.

Installation Notes

Drill blanks are raw stock and require grinding by a qualified machinist or tool grinder before use as a cutting tool. Secure the blank properly in a tool and cutter grinder or surface grinder with appropriate wheel dressing and work-holding equipment. Always wear eye protection and follow shop safety protocols during grinding operations. Finished tools should be inspected for proper geometry and surface finish before installation in production equipment.
