Value Collection 63323216 Drill Blank Letter R Hss

Product Description

The VALUE COLLECTION 63323216 is a letter R drill blank made from high speed steel with a bright, uncoated finish. A drill blank is a precision-ground cylindrical rod used as the raw stock for custom tooling, reamer stock, punch fabrication, or as a transfer punch in layout and machining work. This blank measures 0.3390 inches in diameter and 4-3/4 inches in overall length, offering the dimensional consistency required for accurate tool grinding or press-fit applications. Machinists, tool and die makers, and maintenance technicians working in metalworking shops are the primary users of this type of stock.

Drill blanks serve as versatile raw material in production and job shop environments. This letter R blank is suited for applications where a precise 0.3390-inch diameter cylinder is needed prior to grinding flutes, threading, or other secondary operations. It is also used directly as a locating pin, transfer punch, or alignment tool in fixture work and layout operations. The high speed steel construction handles the demands of light grinding and general shop use without requiring special handling.

Key Features

• Letter R size with a decimal equivalent of 0.3390 inches for precise dimensional reference
• High speed steel construction provides hardness and wear resistance suitable for tool grinding and light-duty tooling applications
• Bright, uncoated finish allows easy visual inspection and dimensional verification before secondary operations
• 4-3/4-inch overall length provides adequate stock for most standard blank-to-tool conversions
• Consistent diameter tolerances support use as locating pins, transfer punches, or reamer blanks

Compatibility

Designed as a standard letter R drill blank for use in metalworking, tool grinding, and fixture fabrication applications requiring a 0.3390-inch diameter high speed steel cylinder.

Installation Notes

Drill blanks are handled and installed by machinists and tool and die makers using standard bench and surface grinding equipment. Always verify dimensional tolerances with a micrometer before committing the blank to a secondary operation. Use appropriate personal protective equipment when grinding high speed steel. Store blanks in a dry environment to prevent surface oxidation, even on uncoated stock.
