Description

Product Overview

The Cleveland #7 O.D. HSS Taper Pin Reamer is engineered for exacting tolerances and long‑lasting performance. Constructed from premium high‑speed steel (HSS), the tool resists wear and maintains sharp cutting edges even under high temperature and heavy load conditions. Its six‑flute spiral geometry is specifically designed to promote efficient chip evacuation, reducing heat buildup and extending tool life. The reamer provides a reaming range from 0.3297 to 0.4220 inches, covering a critical spectrum of applications in aerospace, automotive, and precision manufacturing. Each unit is manufactured in the United States by M & J Tooling, ensuring strict quality control and adherence to industry standards. The product’s dimensions, material composition, and tolerances are carefully calibrated to meet the demands of professional machinists who require reliability, repeatability, and superior surface finish on every pass.

Usage

This reamer excels in environments where precision and consistency are paramount. It is ideally suited for creating tapered holes in aluminum alloys, titanium, stainless steel, and other high‑strength materials commonly found in aerospace components, medical devices, and high‑performance engine parts. The tool’s six‑flute design allows for smooth operation in both CNC and manual machining setups, making it versatile for a range of production volumes—from low‑batch prototyping to high‑volume manufacturing. Operators appreciate the ergonomic handle and balanced weight distribution, which reduce fatigue during extended use. The reamer’s compatibility with standard collet sizes and its ability to maintain tight tolerances across multiple passes make it a reliable choice for technicians, engineers, and hobbyists seeking professional‑grade results without the need for frequent tool changes.
