Value Collection S554448A Hss Drill Blank Coated

Product Description

The VALUE COLLECTION S554448A is a high speed steel drill blank designed for use in tooling, gauging, and precision machining applications. Drill blanks serve as the raw stock from which custom cutting tools, punches, and gauges are ground or fabricated to specification. This blank is coated to improve surface hardness and wear resistance, extending tool life under typical shop conditions. The blank diameter is held to a tolerance of -0.0005 inches, making it suitable for applications that require close dimensional control. Machinists, tool-and-die makers, and maintenance technicians are the primary users of this type of stock.

Drill blanks of this type are used in job shops, production machining environments, and maintenance departments where custom tooling is ground in-house. The coated high speed steel construction suits general-purpose cutting tool fabrication as well as fixture and gauging applications. The tight diameter tolerance supports consistent fitment in toolholders and guide bushings without secondary sizing operations.

Key Features

• High speed steel construction provides toughness and wear resistance for machining and tooling use
• Coated finish improves surface hardness and reduces friction during service
• Blank diameter tolerance of -0.0005 inches supports precision grinding and fabrication
• Sold individually, allowing single-piece procurement for low-volume or one-off tooling needs

Compatibility

Designed as a general-purpose high speed steel drill blank suitable for custom tool grinding, gauge making, and precision tooling fabrication in standard machine shop applications.

Installation Notes

Drill blanks are raw stock and require grinding or machining by a qualified toolmaker before use as a finished tool. Secure the blank properly in the grinding fixture and verify dimensional accuracy after each grinding pass. Follow applicable shop safety practices when operating surface grinders or tool-and-cutter grinders, including use of appropriate eye protection and wheel guards.
