Face Mill R8-FMB22 7/16-20UNF by Yunir Low Cutting Hardened Steel

Description

Product Overview

The Yunir Face Mill R8-FMB22 7/16-20UNF is engineered for precision side and face milling across a broad spectrum of materials. Constructed from hardened steel that has undergone a rigorous heat‑treatment process, the cutter delivers exceptional wear resistance while maintaining a sharp cutting edge for extended service life. Its low‑cutting geometry reduces cutting forces, which translates into smoother operation, lower vibration, and improved surface finish on the workpiece. The cutter’s dimensions—5.91 inches in length and 1.77 inches in width—provide a compact footprint that fits comfortably into standard arbor setups, and the 1.33‑pound weight ensures easy handling without sacrificing rigidity.

Designed with a large chip clearance channel, the Face Mill efficiently evacuates chips, preventing re‑cutting and heat buildup that can compromise tool performance. The 7/16‑20UNF thread offers a secure, quick‑change connection to the milling machine spindle, while the locked screw design guarantees stability during high‑speed operation. The cutter’s versatility is highlighted by its ability to process steel, aluminum, plastics, and composite materials, making it a valuable addition to any machining arsenal.

Usage

Machinists and production engineers will find the Yunir Face Mill ideal for a variety of applications, from aerospace component finishing to automotive part prototyping. The low‑cutting design is particularly beneficial when machining delicate alloys or thin‑walled sections where excessive force could cause deformation. In CNC environments, the cutter can be programmed for precise depth‑of‑cut control, enabling consistent material removal and repeatable results across large production runs. For manual milling setups, the ergonomic handle and balanced weight reduce operator fatigue, allowing extended use without compromising accuracy.

Typical use cases include creating flat surfaces, contouring edges, and performing shoulder milling operations on cast iron, stainless steel, and high‑strength aluminum alloys. The large chip evacuation channel also makes the cutter suitable for high‑speed machining of thermoplastic polymers, where chip buildup can otherwise lead to tool clogging. By integrating the Face Mill into a standard machining workflow, shops can achieve tighter tolerances, smoother finishes, and reduced cycle times.
