Chicago-latrobe 46808 Drill Blank 1/8 in Hss Bright

Product Description

The CHICAGO-LATROBE 46808 is a high speed steel drill blank used as a precision ground cylindrical rod for custom toolmaking, drill point regrinding, and gauge pin applications. It measures 0.125 inches (1/8 inch) in diameter and 2.75 inches in length, with a tight diameter tolerance of +0.0000 to -0.0002 inches. The bright, uncoated finish leaves the steel surface ready for secondary operations such as coating, heat treatment, or custom grinding. Machinists, tool-and-die makers, and precision fabricators rely on this type of blank when building or reconditioning cutting tools to exact specifications.

This drill blank is suited for use in toolrooms, job shops, and production environments where fractional-inch tooling is standard. The 1/8-inch diameter makes it a common size for small-hole tooling, instrument work, and jig boring setups. Its high speed steel construction holds up under moderate heat and cutting forces, making it appropriate for general-purpose toolmaking across a wide range of metals and materials.

Key Features

• High speed steel construction for durability and heat resistance during cutting and grinding operations
• Bright, uncoated finish ready for secondary operations including custom coatings or heat treatment
• Tight diameter tolerance of +0.0000 to -0.0002 inches for precise fitment in tooling applications
• Fractional-inch sizing (1/8 inch diameter) compatible with standard inch-system toolholders and fixtures
• Compact 2.75-inch length suitable for short-reach toolmaking and regrinding stock

Compatibility

Designed as a standard fractional-inch drill blank for use in toolroom and production applications requiring a 1/8-inch diameter high speed steel cylindrical blank.

Installation Notes

Drill blanks are installed or used by machinists and tool-and-die professionals in toolroom settings. Secure the blank properly in the appropriate holder or fixture before grinding or machining operations. Always wear appropriate eye protection and follow shop safety procedures when grinding high speed steel. Do not use the blank beyond its rated material capacity or attempt to use it as a finished cutting tool without proper point grinding.
