Value Collection 01108778 Drill Blank Size 77 Hss

Product Description

The VALUE COLLECTION 01108778 is a wire gauge size 77 drill blank made from high speed steel with a bright, uncoated finish. At 0.0180 inches in decimal diameter and an overall length of 7/8 inch, this blank is a precision-ground cylindrical rod used as raw stock for custom tooling, gauging, and inspection applications. Machinists, tool and die makers, and toolroom technicians use drill blanks to fabricate custom punches, pins, and specialty cutting tools when off-the-shelf tooling does not meet exact dimensional requirements.

Wire gauge drill blanks in the number 77 size are common in precision toolroom environments and light manufacturing shops. They serve as starting material for ground and lapped tools, go/no-go gauge pins, alignment pins, and small punch blanks. The bright uncoated surface finish is suitable for applications where additional coatings or further grinding will be applied by the end user. This size is appropriate for light-duty toolmaking and instrument work requiring tight dimensional control at small diameters.

Key Features

• Wire gauge size 77 with a decimal equivalent diameter of 0.0180 inches
• High speed steel construction for hardness and wear resistance in toolroom applications
• Bright, uncoated finish ready for secondary grinding, lapping, or coating operations
• Overall length of 7/8 inch suits short-reach pin and punch fabrication
• Precision-ground cylindrical stock for consistent dimensional accuracy

Compatibility

Designed as a general-purpose wire gauge drill blank for use in toolroom, gauge, and precision manufacturing applications requiring a number 77 size blank in high speed steel.

Installation Notes

Drill blanks are raw stock and require machining, grinding, or lapping before use as finished tools or gauge pins. Work with appropriate toolroom equipment and personal protective equipment when cutting or grinding high speed steel. Verify final ground dimensions with calibrated measuring instruments before use in critical gauging or assembly applications.
