Spi 13-968-3 Drill Point Gage 118 Degree Steel

Product Description

The SPI 13-968-3 is a 118-degree bevel angle drill point gage made from steel, used to verify the included angle of twist drill points before and after grinding. Accurate drill point geometry is critical for clean entry, reduced thrust, and extended bit life. This gage measures bevel angle with 1/32-inch graduation increments, giving technicians a fast, direct reference check without the need for optical comparators or angle blocks. At 0.04 inches thick, it slides easily alongside standard steel rules and sits flat on a bench or in a tool kit without adding bulk. Machinists, maintenance technicians, and toolroom personnel typically use this type of gage as part of a routine drill-sharpening workflow.

This gage is suited for use in machine shops, maintenance facilities, and toolrooms where drills are resharpened in-house. It is designed to work alongside steel rules that are 0.75 inches wide, making it a practical companion to standard layout and measurement setups. The removable end clip allows the gage to be attached to a steel rule for convenient storage and quick access at the grinder or workbench. Applications include verifying 118-degree point geometry on standard jobber-length twist drills used in ferrous and non-ferrous materials.

Key Features

• 118-degree bevel angle reference for standard twist drill point verification
• 1/32-inch bevel graduation for direct, readable angle checks
• Steel construction for durability in shop environments
• 0.04-inch thickness fits alongside 0.75-inch-wide steel rules
• Removable end clip for attachment to a steel rule

Compatibility

Designed for use with steel rules 0.75 inches wide as a companion measurement tool for verifying 118-degree drill point angles on standard twist drills.

Installation Notes

This is a passive measurement gage requiring no installation. Handle with care to avoid burrs or nicks on the reference edges, as surface damage will affect angle accuracy. Store attached to a steel rule using the included removable end clip to protect the gage and keep it accessible. Calibration should be verified periodically against a known angle standard in quality-critical environments.
