HARFINGTON Inside Caliper 500mm (20 Inch) Color 1 Tool Steel

Description

Product Overview

The HARFINGTON Inside Caliper is engineered for precision measurement of internal diameters, offering a maximum opening of 500 mm (20 in). Its robust construction from heat‑treated tool steel provides exceptional durability, while a chrome finish adds corrosion resistance and a sleek, reflective surface that reduces glare during use. The firm friction joint delivers a stable, burr‑free feel, ensuring that measurements remain consistent even after prolonged operation.

Designed with a clear, easy‑read scale and a smooth sliding mechanism, the caliper allows users to quickly lock in measurements without the risk of slippage. The ergonomic grip area reduces hand fatigue, making it suitable for extended sessions in workshops, laboratories, or field environments. Each unit is calibrated to industry standards, guaranteeing accuracy within tight tolerances for both hobbyist and professional applications.

Usage

This inside caliper excels in a variety of settings, from precision woodworking and metal fabrication to model making and repair work. Its compact size and lightweight design (approximately 1.76 ounces) enable easy handling in tight spaces, while the firm joint maintains measurement integrity when measuring small to medium cylindrical parts such as pipe interiors, bearing housings, and drilled holes.

For optimal performance, keep the caliper clean and dry before each use. After measuring, wipe the steel surface with a soft cloth to remove any debris or moisture that could affect future accuracy. Avoid applying excessive force on the sliding jaw, as this may damage the delicate friction mechanism. Regularly inspect the chrome coating for signs of wear and re‑apply a light oil if the movement feels stiff.
