External Internal Radius Gauge R0.3‑1.5MM & R1‑6.5MM for Machinists

Description

Product Overview

The External Internal Radius Gauge is engineered to deliver high‑precision leaf measurements for a wide range of radii commonly encountered in machining and inspection tasks. Constructed from hardened stainless steel, the gauge resists wear, corrosion, and deformation, ensuring long‑term accuracy even in demanding shop floor environments. Two interchangeable leaf sets cover the critical measurement spans of R0.3‑1.5 mm and R1‑6.5 mm, providing seamless transition between fine and medium‑size radius checks. Each leaf is calibrated to industry standards and features clear, etched scale markings that remain legible after repeated use. The ergonomic handle offers a comfortable grip, reducing hand fatigue during prolonged inspections, while the slim profile enables access to tight spaces where larger tools cannot reach. This gauge is a versatile addition to any machinist’s toolkit, suitable for routine production verification, prototype development, and quality control audits.

Usage

Designed with the practical needs of machinists, toolmakers, and quality inspectors in mind, the gauge excels in a variety of real‑world scenarios. In a CNC machining environment, operators can quickly verify the external radius of turned shafts or the internal radius of bored holes without interrupting the production flow. The lightweight construction allows the gauge to be carried easily across the shop floor, and the interchangeable leaves mean a single tool can service multiple measurement ranges, reducing the need for a large inventory of specialized gauges. In maintenance workshops, the gauge assists in diagnosing wear patterns on components such as gears, camshafts, and bearing housings, helping technicians determine when parts require replacement or re‑machining. Its durability also makes it suitable for field service applications, where ruggedness and reliability are paramount. Whether used on a bench, in a production line, or on‑site, the gauge delivers consistent, repeatable results.

Why Choose Us

Our commitment to quality begins with material selection; the gauge is forged from premium stainless steel that meets ISO 9001 standards for dimensional stability. Each unit undergoes a rigorous calibration process performed by certified metrologists, guaranteeing that the scale markings are within ±0.01 mm of the nominal values. We back our product with a comprehensive warranty and a responsive customer support team that provides technical assistance, calibration services, and replacement parts when needed. Unlike many generic gauges that rely on plastic components, our all‑metal construction ensures that the tool maintains its accuracy over years of heavy use. Additionally, we offer custom engraving options for corporate branding or specific part numbers, allowing you to integrate the gauge seamlessly into your existing workflow. Choosing our gauge means investing in a tool that combines precision engineering, durability, and exceptional after‑sales service.

FAQ

What materials can the gauge measure?

The gauge is suitable for measuring radii on metal components such as steel, aluminum, brass, and copper, as well as on hardened alloys and coated surfaces.

How often should the gauge be recalibrated?

We recommend a professional recalibration at least once a year, or sooner if the gauge experiences a shock or is used in a high‑temperature environment.

Can the leaves be replaced if damaged?

Yes, the interchangeable leaves are sold separately and can be swapped out quickly without the need for special tools.

Is the gauge compatible with metric and imperial measurement systems?

The scale markings are provided in metric units (millimeters). For imperial conversions, a simple conversion chart is included in the packaging.

What warranty does the gauge include?

We offer a two‑year limited warranty covering manufacturing defects and provide free technical support throughout the warranty period.
