Value Collection 01100155 Drill Blank 15/64 in Hss

Product Description

The VALUE COLLECTION 01100155 is a high speed steel drill blank designed for use in custom tooling applications where a precise, unfinished cylindrical rod is required as a starting point for fabrication. Measuring 15/64 inch (0.2344 inch) in diameter and 3-7/8 inches in overall length, this blank arrives with a bright, uncoated finish that leaves the surface ready for grinding, reaming, or other secondary machining operations. It is sized for compatibility with standard fractional drill configurations and weighs approximately 0.05 pounds. Machinists, tool and die makers, and shop technicians working in metalworking environments are the primary users of this type of blank.

Drill blanks in this size range are used in job shops, maintenance facilities, and production tooling departments where custom drill geometries, reamers, or punch pins are manufactured in-house. The 15/64 inch diameter is a commonly requested fractional increment for applications requiring close-tolerance bores or custom tool profiles. The high speed steel material supports re-grinding and holds an edge under moderate heat conditions typical of machining steel, aluminum, and similar materials.

Key Features

• High speed steel construction supports secondary grinding and re-sharpening
• Bright, uncoated finish leaves surface in ready-to-machine condition
• 15/64 inch (0.2344 inch) diameter matches standard fractional drill increment
• 3-7/8 inch overall length provides adequate stock for most custom tooling applications
• Lightweight at 0.05 pounds for easy handling and low shipping impact

Compatibility

Designed as a general-purpose drill blank for use in custom tooling fabrication across a wide range of metalworking and machining applications where a 15/64 inch diameter high speed steel blank is specified.

Installation Notes

Drill blanks require secondary machining before use as a cutting tool and should only be handled and processed by qualified machinists or toolmakers using appropriate grinding equipment. Secure the blank properly in a tool and cutter grinder or appropriate fixture before performing any shaping operations. Follow applicable shop safety procedures, including eye protection and machine guarding, when grinding high speed steel. Do not attempt to use an unground blank as a drill in a rotating spindle.
