Starrett 64509 Dial Caliper 225 Mm Stainless Steel

Product Description

The STARRETT 64509 is a metric dial caliper designed for precise dimensional measurement in shop, field, and maintenance environments. It covers a 225 mm measurement range with a 0.02 mm dial graduation, delivering an accuracy of 0.03 mm per reading. The caliper body and jaws are constructed from satin-chrome-finished stainless steel, providing corrosion resistance and durability under regular use. The yellow dial face on a black dial case provides high-contrast readability in varied lighting conditions. Machinists, millwrights, pipefitters, and maintenance technicians rely on this tool for inside, outside, depth, and step measurements in a single instrument.

The 64509 is suited for residential and commercial trade applications where metric measurement is required, including HVAC component sizing, plumbing fitting verification, and general mechanical maintenance. The 1.5-inch (38.10 mm) jaw length accommodates a wide range of workpiece geometries. The rack-and-gear drive mechanism and Starrett 120M measuring surfaces ensure consistent jaw travel and repeatable readings across the full 225 mm range. It ships as a single caliper with no additional accessories included.

Installation Notes

No installation is required for this hand tool. Before use, verify the jaws close fully to a zero reading and adjust the bezel if needed to re-zero the dial. Keep measuring surfaces clean and free of debris to maintain accuracy. Store in a protective case away from moisture when not in use to preserve the stainless steel finish and dial mechanism.
