Value Collection 01100312 Drill Blank 31/64 in Hss

Product Description

The VALUE COLLECTION 01100312 is a high speed steel drill blank sized at 31/64 inch (0.4844 inch decimal) diameter with a 5-7/8 inch overall length. Drill blanks are ground, unfluted rod stock used as the starting material for custom tooling fabrication — machinists grind them to create special-purpose drills, reamers, punches, and gauges. This blank carries a bright, uncoated finish, which means the steel surface is left in its natural ground state without any additional coating treatment. It is a standard item for toolrooms, prototype shops, and precision machining operations where off-the-shelf drill geometries do not meet the required specification.

This drill blank is suited for toolroom use in both manual and CNC machine shops. It is typically selected when a specific hole diameter, flute geometry, or point angle must be ground to a custom profile. The 31/64 inch size falls between standard fractional drill sizes, making it particularly useful where a close-tolerance reamer blank or a non-standard drill form is needed. Machinists and tool grinders in job shops, maintenance departments, and production facilities regularly stock blanks in this size range for on-demand tooling work.

Key Features

• High speed steel construction provides the hardness and wear resistance needed for custom tool grinding
• Bright, uncoated finish allows direct use as ground stock without surface treatment interference
• 31/64 inch (0.4844 inch) diameter fills the gap between standard fractional drill sizes
• 5-7/8 inch overall length provides sufficient stock for grinding custom tool geometries
• Single-piece package quantity supports individual toolroom or maintenance use

Compatibility

Designed as a general-purpose drill blank for toolroom grinding applications where a 31/64 inch diameter high speed steel blank is required. No specific machine or system compatibility is stated by the manufacturer for this blank stock item.

Installation Notes

Drill blanks are raw stock and require grinding before use as finished tooling. A qualified machinist or tool grinder should perform all shaping operations using appropriate grinding equipment. Secure the blank properly in a tool and cutter grinder or surface grinder fixture before material removal begins. Always wear appropriate eye protection and follow shop safety procedures when grinding high speed steel.
