Condition

Used (Excellent / Vintage).

This machinist protractor is in excellent used condition, housed in its original fitted wooden case. The satin chrome finish on the scale is clean and glare-free, and the locking screw operates smoothly. The edges of the blade are sharp and free from major nicks. It is a well-preserved example of Japanese precision tooling.

Product Overview

The SK 495DA is a classic machinist’s bevel protractor designed for measuring and laying out angles with high reliability. Unlike complex vernier protractors, this model features a clear, easy-to-read degree scale (0-180°) which is sufficient for most general workshop fabrication, welding tasks, and setting cutting angles on drop saws.

The instrument is made from hardened stainless steel with a satin chrome finish to prevent rust and reduce glare under workshop lighting. It features a sliding blade that can be locked in position via a knurled thumb screw, allowing you to measure depth or transfer angles directly from a workpiece to a machine setup. The included wooden case protects the tool from impact and dust when not in use.
