Value Collection 63323075 Drill Blank Letter C Hss

Product Description

The VALUE COLLECTION 63323075 is a letter-size drill blank in size C, ground to a 0.2420 inch decimal diameter and 4 inches overall length. Drill blanks are unfluted, precision-ground cylindrical rods used as the starting stock for custom toolmaking, gauge pins, punch blanks, and specialty tooling fabrication. This blank is manufactured from high speed steel (HSS) with a bright, uncoated finish, making it easy to inspect surface condition and apply custom coatings or heat treatments after machining. Machinists and tool-and-die makers rely on this format when standard off-the-shelf drill geometry does not meet the application requirement.

This drill blank is suited for job shops, maintenance departments, and toolrooms that fabricate custom cutting tools, reamers, or punches from raw stock. The HSS construction handles moderate heat and wear well across a range of ferrous and non-ferrous workpiece materials. At 4 inches OAL, it provides adequate stock length for most bench-grinder or tool-and-cutter-grinder operations used to produce custom tooling profiles.

Key Features

• Letter C size with 0.2420 inch decimal equivalent for precise tool fabrication
• 4 inch overall length provides sufficient stock for custom grinding operations
• High speed steel construction offers good heat resistance and wear life
• Bright, uncoated finish allows visual inspection and accepts post-process coatings
• Unfluted blank format suitable for use as gauge pin stock, punch blank, or custom drill stock

Compatibility

Designed as a general-purpose HSS drill blank for toolroom and job-shop use where a letter-size C diameter blank at 4 inches OAL is required.

Installation Notes

Machining or grinding HSS blanks should be performed by a qualified machinist or tool-and-die maker using appropriate tool-and-cutter grinding equipment. Secure the blank firmly in a proper fixture or vise before any grinding or turning operation. Allow adequate cooling during grinding to prevent heat buildup that can alter the steel temper. Handle ground blanks with care, as precision-ground surfaces are susceptible to nicks and surface damage that affect final tool accuracy.
