Swivel measuring instrument with analog dial indicator for internal measurement, 20-40 mm

Description

Schwenk internal chamfer gauge, 90°, 20 – 40 mm is a Schwenk precision instrument from the STANDARD LINE series — used for workshop measurement, inspection, and reference work in machine shop and manufacturing environments. Measuring range 20 – 40 mm. Hardened and ground reference surfaces ensure repeatable measurements; the instrument is designed for handheld or fixture-mounted use depending on the workshop application.

STANDARD LINE build quality. Hardened and ground reference surfaces and contact points for repeatable measurements; matched to Schwenk precision quality class. The instrument integrates with standard inspection workflows in metrology labs and machine shop QC stations.

Usage: position the instrument against the workpiece’s reference surface or feature, and perform the measurement according to the instrument’s standard procedure (depending on type — direct reading, comparative deviation, go/no-go verification, or wrung-stack reference). Zero-verify against a setting standard during periodic verification. Document with a calibration certificate. The instrument’s design supports both one-off inspection and back-to-back QC workflows; its hardened reference surfaces withstand wear from regular workshop use over years of service.

Common applications: workshop incoming inspection of components, on-machine setup checks, fitter and toolmaker bench measurement, calibration lab reference work, and QC workflows within the Schwenk product line where this instrument’s specific role is applicable. The INTERNAL MEASURING INSTRUMENTS category is the standard workshop tool for measurement/reference tasks.
