Value Collection 63323273 Drill Blank Letter X Hss

Product Description

The VALUE COLLECTION 63323273 is a Letter X drill blank machined from high speed steel with a bright, uncoated finish. Drill blanks serve as precision-ground cylindrical stock used for custom tooling, reamer blanks, punch blanks, transfer punches, and gauge pins. This blank measures 0.3970 inches in decimal diameter and 5.125 inches in overall length, providing sufficient shank stock for a range of tooling and fixture applications. The bright finish means no coating treatment has been applied, leaving the steel at its native ground surface for applications where coating interference is a concern. Licensed machinists and tool-and-die technicians are the primary users.

This drill blank is suited for machine shops, toolrooms, and maintenance departments requiring precision-diameter stock in standard letter sizing. Letter X corresponds to 0.3970 inches, placing it in a range commonly used for custom reamer preparation, jig boring setups, and specialty punch fabrication. The 5.125-inch overall length gives machinists flexibility to cut and finish to the required working length on a lathe or surface grinder.

Key Features

• Letter X size at 0.3970 inches decimal diameter for precise fitment in letter-series tooling applications
• High speed steel construction for hardness and wear resistance under machining loads
• Bright, uncoated finish preserves true ground diameter without coating buildup
• 5.125-inch overall length provides stock for trimming and finishing to required length
• Single-piece packaging suits individual toolroom orders and one-off custom tooling jobs

Compatibility

Designed as a standard letter-series drill blank suitable for use in toolroom, machine shop, and maintenance applications requiring 0.3970-inch diameter precision-ground high speed steel stock.

Installation Notes

Drill blanks are worked on lathes, surface grinders, and cylindrical grinders by qualified machinists. Secure the workpiece properly in the machine before cutting or grinding to finished dimensions. Wear appropriate eye protection and follow shop-floor safety protocols when machining high speed steel stock. Do not attempt to use an unfinished blank as a cutting tool without proper grinding to the required geometry and relief angles.
