Value Collection 63323224 Drill Blank Letter S Hss

Product Description

The VALUE COLLECTION 63323224 is a Letter S drill blank ground from high speed steel and supplied in a bright, uncoated finish. At 0.3480 inches in diameter and 4-7/8 inches overall length, it serves as raw stock for machinists and tool-and-die technicians who grind custom cutting tools, reamers, punches, or specialty drill profiles to precise specifications. The bright finish leaves the steel in its as-ground state without any coating that could interfere with secondary grinding or heat treating. High speed steel construction provides the hardness and toughness needed for reshaping under bench grinder or surface grinder conditions.

Drill blanks of this type are used in machine shops, maintenance departments, and toolmaking environments where standard off-the-shelf drill geometry does not meet the required application. Technicians use blanks like the 63323224 to fabricate step tools, form tools, custom pilots, or drill-and-tap combinations. The Letter S sizing designation corresponds to 0.3480 inches, placing this blank in the range commonly used for close-tolerance reaming prep or tapping undersize holes in production setups. Suitable for both light-duty prototype work and repeat production tooling tasks.

Key Features

• Letter S size at 0.3480 inches decimal equivalent for precise tool layout
• High speed steel construction supports secondary grinding and reshaping
• Bright, uncoated finish eliminates coating interference during custom profiling
• 4-7/8 inches overall length provides adequate stock for most custom tool forms
• Sold individually, allowing single-piece procurement for prototyping or replacement

Compatibility

Designed as a general-purpose Letter S drill blank suitable for use in standard tool-and-die, machining, and maintenance grinding applications where a 0.3480-inch diameter high speed steel blank is required.

Installation Notes

Drill blanks are shaped by qualified machinists or tool grinders using bench grinders, surface grinders, or tool-and-cutter grinders. Secure the blank firmly in an appropriate fixture or vise before grinding to prevent slippage and maintain concentricity. Allow the steel to cool during grinding to avoid drawing the temper and reducing hardness. Finished tools should be inspected for geometry and runout before use in production applications.
