Value Collection 63323208 Drill Blank Letter Q Hss

Product Description

The VALUE COLLECTION 63323208 is a Letter Q drill blank made from high speed steel with a bright, uncoated finish. Drill blanks are precision-ground cylindrical rods used as starting stock for custom tooling, including special-purpose drill bits, punches, and gauging tools. This blank measures 0.3320 inches in diameter and 4-3/4 inches in overall length, making it suitable for a range of toolroom and fabrication applications. The high speed steel construction provides the hardness and wear resistance needed for cutting-tool manufacturing and precision machining work. Machinists and toolmakers grind or modify these blanks to produce finished cutting tools to exact specifications.

This drill blank is used in toolrooms, machine shops, and fabrication facilities where custom or specialty tooling is needed. The Letter Q designation corresponds to a decimal diameter of 0.3320 inches, fitting standard letter-series tooling conventions. Typical applications include producing custom drill points, step tools, punch blanks, or gauge pins. The bright uncoated finish allows for easy inspection and further surface treatment if required. This blank is sold individually and is appropriate for low-volume custom tooling jobs as well as prototyping work.

Key Features

• Letter Q size with 0.3320 inch decimal diameter for standard letter-series tooling compatibility
• High speed steel construction provides hardness and durability for cutting-tool applications
• Bright uncoated finish allows visual inspection and accepts additional surface treatments
• 4-3/4 inch overall length provides adequate stock for grinding custom tool geometries
• Sold as a single unit, suitable for both prototyping and production toolroom use

Compatibility

Designed as a standard letter-series drill blank for use in toolroom, machining, and fabrication applications where a 0.3320 inch diameter high speed steel blank is required.

Installation Notes

Drill blanks are raw stock and require grinding or machining by a qualified toolmaker before use as finished cutting tools. Use appropriate personal protective equipment when grinding high speed steel, and follow shop safety protocols for tool grinding operations. Inspect the blank for straightness and surface condition before beginning any grinding work. Store blanks horizontally or in a dedicated tool rack to prevent nicks, bending, or surface damage.
