Raseparter Carbon Steel Hole Gauge 5/16in‑6in Double‑Acting Tool

Description

Product Overview

The Raseparter hole gauge is engineered for accurate internal dimension verification across a wide range of hole sizes. Constructed from high‑grade carbon steel with a protective chrome‑plated surface, the tool resists wear and corrosion in demanding environments. Its measurement range spans 5/16in (8mm) to 6in (150mm), covering most standard industrial applications. The rigid handle and double‑acting design automatically center the gauge in the bore, while a knurled locking knob secures the spring tension for consistent readings.

Usage

Designed for machinists, maintenance engineers, and quality‑control personnel, this gauge excels in settings where quick, repeatable internal measurements are critical. Whether checking engine cylinders, hydraulic ports, or precision‑machined components, the gauge expands into the hole, locks in place, and allows you to read the final size with a micrometer or caliper. Its compact 8.27 x 6.5 x 0.79‑inch size and lightweight 10.23‑ounce build make it easy to carry in toolboxes or on‑site kits.

FAQ

How do I lock the gauge in place?

Expand the gauge into the hole, then turn the knurled locking knob until the spring tension feels firm. This secures the gauge for measurement.

Can I use this gauge with a digital caliper?

Yes, after locking the gauge, read the external dimension with any standard caliper or micrometer for the final size.

What maintenance is required?

Wipe the chrome surface after use to remove debris and apply a light oil periodically to keep the spring mechanism smooth.

Is the gauge suitable for high‑temperature environments?

The carbon steel construction tolerates typical workshop temperatures, but extreme heat may affect spring performance.

What is the warranty period?

Raseparter offers a one‑year limited warranty covering manufacturing defects.
