Value Collection 63323281 Drill Blank Letter Y Hss

Product Description

The VALUE COLLECTION 63323281 is a Letter Y drill blank ground from high speed steel and supplied with a bright, uncoated finish. Drill blanks are precision-ground cylindrical rods used as the starting material for custom tooling, gauge pins, punch blanks, and specialty drill fabrication. This blank measures 0.4040 inches in diameter and 5-1/4 inches in overall length, providing sufficient stock for a range of shop-made tooling applications. The bright finish indicates no coating or surface treatment has been applied, leaving the steel ready for secondary grinding, heat treatment, or direct use where an uncoated tool is preferred. Machinists, tool-and-die makers, and maintenance technicians typically work with this style of blank.

Letter Y drill blanks at 0.4040 inches diameter are used in general metalworking, tool room, and maintenance environments. Common applications include the production of custom drills, pilots, reamers, and gauging fixtures. The 5-1/4 inch length provides adequate reach for most bench-grinder or surface-grinder regrinding setups. This blank is appropriate for both production tool shops and maintenance repair operations where off-the-shelf drill sizes do not match the required bore diameter.

Key Features

• Letter Y size designation — 0.4040 inch decimal equivalent diameter
• High speed steel construction for toughness and regrindability
• Bright, uncoated finish — ready for secondary operations or direct use
• 5-1/4 inch overall length provides ample stock for grinding and shaping
• UNSPSC Code 23242100 for procurement and catalog classification

Compatibility

Designed as a general-purpose drill blank suitable for tool room fabrication, custom drill grinding, and gauge pin applications where a 0.4040 inch diameter high speed steel blank is required.

Installation Notes

Drill blanks are raw stock and require secondary grinding or machining before use as a finished tool. Handle with care to avoid nicking the ground surface, which can introduce stress risers. Use appropriate personal protective equipment when grinding high speed steel. Secure work firmly in a tool post grinder or surface grinder and ensure the blank is supported adequately along its length to prevent deflection.
