Description

The HZZ Spring Inside Calliper represents professional-grade precision for internal diameter measurement applications. Engineered with a robust spring mechanism that maintains consistent tension, this tool ensures reliable and repeatable measurements of bores, tubes, and internal dimensions. The hardened steel construction provides exceptional durability while resisting wear from frequent use in workshop environments.

Key features include a finely knurled adjustment wheel that allows for precise micro-adjustments when measuring internal spaces. The spring-loaded design automatically maintains measurement settings, enabling quick and efficient transfer of dimensions from workpiece to measuring device. The tapered measuring tips are precision-ground to a fine point, allowing access to narrow grooves and small diameter holes with excellent accuracy.

This inside calliper is particularly valued by machinists for setting lathes, by mechanics for measuring cylinder bores, and by quality control technicians for verifying internal dimensions of manufactured parts. The balanced design provides comfortable handling during extended use, while the spring tension can be adjusted to suit different measurement requirements.

Sizes : 4″, 6″, 8″, 10″, 12″,15″,18″ & 24″.
