Value Collection 63323133 Drill Blank Letter J Hss

Product Description

The VALUE COLLECTION 63323133 is a Letter J drill blank made from high speed steel for use in precision drilling and custom tooling applications. This blank measures 0.2768 inches in diameter and 4.125 inches in overall length, with a bright, uncoated finish that suits a wide range of general-purpose machining environments. Drill blanks serve as the raw stock for custom-ground drill bits, gauging pins, and other precision tools. Machinists, toolmakers, and tool-and-die professionals select blanks of this type when standard off-the-shelf drills cannot meet specific tolerance or geometry requirements.

This drill blank is suited for use in machine shops, job shops, and maintenance facilities where custom tooling is fabricated or precision hole diameters must be held to close tolerances. Letter J sizing corresponds to a 0.2768-inch decimal equivalent, placing it in the range commonly used for tapping undersized holes, reaming, and precision fit applications. The high speed steel construction performs well across ferrous and non-ferrous materials at conventional cutting speeds.

Compatibility

Designed as a general-purpose Letter J drill blank suitable for use in custom tooling fabrication, gauging, and precision machining applications requiring a 0.2768-inch diameter high speed steel blank.

Installation Notes

Drill blanks are typically handled by machinists and tool grinders in shop environments. Before grinding or finishing, secure the blank properly in a tool-and-cutter grinder with appropriate work-holding fixtures. Inspect the blank for straightness and surface defects prior to use. Follow shop safety protocols for grinding operations, including the use of eye protection and proper wheel guards.
