Mitutoyo 50-100mm Dial Bore Gauge 511-128-05

Description

CUSTOMS DELAYS, Octobers deliveries will be delayed.

Condition: Used but in pristine working condition. The gauge body is complete with all standard accessories (anvils, spacers, rod, case, etc.), though no dial indicator is included. It accepts standard 8 mm stem dial indicators from Mitutoyo, Peacock, or many other brands.

This 511-128-05 belongs to Mitutoyo’s Series 511 Standard Dial Bore Gauge line, designed for internal diameter measurement in the 50–100 mm range. It features carbide-tipped contact points for durability and wear resistance, a hollow grip structure to reduce heat transfer from the operator’s hand, and an interchangeable anvil/spacer system to cover the full measurement span with fine adjustment steps. The design ensures reliable repeatability and minimal user-influenced error during measurement.

Use & Application Notes

Ideal for inspecting internal bores, cylinders, sleeves, and housings in the 50–100 mm range.
Suitable for precision machinists, toolmakers, and quality control labs needing internal diameter checks.
Modular design allows flexibility when measuring variable bore sizes using various anvil combinations.
Compatible with standard 8 mm stem dial or test indicators, so users may pair with their preferred gauge brand.
Because it lacks its indicator, buyers should obtain a 0.01 mm dial/test indicator (Mitutoyo, Peacock, etc.) to complete the set.
