Starrett 63695 External Chamfer Gage 1/8 to 1/2 in 3-blade

Product Description

The STARRETT 63695 is an external chamfer gage designed to measure chamfered edges on machined parts and fittings. It uses a 3-blade plunger mechanism to seat accurately against the chamfer face, reading the included angle directly from a white-face dial. The measurement range spans 1/8 inch to 1/2 inch in diameter, and the instrument captures included angles from 90 to 127 degrees. The body and plunger components are constructed from hardened tool steel for wear resistance and dimensional stability under repeated shop use. Machinists, pipefitters, and quality control technicians use this gage to verify chamfer geometry on threaded connections, valve seats, and precision bores.

The 63695 is suited for inspection and production work in machine shops, plumbing fabrication, and HVAC component manufacturing where chamfer angle and diameter conformance must be verified before assembly. It is particularly useful when inspecting pipe fittings, hydraulic couplings, and machined adapters that require tight chamfer tolerances. The white-face dial provides clear readability in typical shop lighting conditions. This gage handles the external chamfer geometry check as a standalone handheld instrument, requiring no external fixtures or mounting hardware for standard use.

Key Features

• 3-blade plunger seats consistently against the chamfer face for repeatable readings
• Measurement range: 1/8 inch to 1/2 inch diameter
• Included angle range: 90 to 127 degrees
• Hardened tool steel construction resists wear during high-cycle inspection use
• White-face dial provides high contrast for fast, accurate reading
• Handheld operation requires no mounting fixtures for standard chamfer checks

Compatibility

Designed for external chamfer measurement on machined parts, pipe fittings, and threaded components with chamfer diameters between 1/8 inch and 1/2 inch and included angles between 90 and 127 degrees.

Installation Notes

This instrument is a handheld measuring gage and does not require installation. Before use, verify the plunger blades are clean and free of debris to ensure accurate seating against the chamfer surface. Handle with care to avoid dropping, which can affect calibration and blade alignment. Periodic calibration against a known reference standard is recommended to maintain measurement accuracy.
