CAT40-FMB27-60 BestParts 6-Flute 80mm Face End Mill with Inserts

Description

Product Overview

The CAT40-FMB27-60 from BestParts is engineered as a high‑performance face end mill cutter designed for demanding CNC milling applications. Featuring a 6‑flute geometry and an 80 mm (3.15 in) cutting diameter, this cutter delivers superior material removal rates while maintaining excellent surface finish quality. The cutter is mounted on a 27 mm (1.06 in) arbor with a 5/8″‑11 thread, providing a secure and rigid connection to the spindle. Included in the package are ten APMT1604 carbide inserts, each with an 85° nose angle and 11° relief angle, optimized for high‑speed machining of a variety of materials. A T15 wrench is also supplied for quick and precise insert changes, reducing downtime and enhancing productivity.

Constructed from premium grade carbide, the inserts offer exceptional wear resistance and thermal stability, allowing the cutter to operate at higher speeds without compromising tool life. The 6‑flute design reduces chip load per tooth, resulting in smoother cuts and lower vibration, which translates to tighter tolerances and better dimensional accuracy. The overall weight of the tool is 5.93 lb, making it easy to handle while still providing the rigidity needed for heavy‑duty machining.

Usage

This face end mill is ideally suited for machining flat surfaces, creating precise grooves, and performing cut‑off operations on a wide range of workpiece materials, including aluminum, steel, and composite alloys. Its high cutting speed and efficient chip evacuation make it a reliable choice for both prototype development and high‑volume production runs. The cutter excels in environments where surface quality is critical, such as aerospace component fabrication, automotive part manufacturing, and precision tooling industries.

Operators can install the CAT40-FMB27-60 on standard CNC milling machines equipped with a compatible 27 mm arbor. The included T15 wrench simplifies insert changes, allowing technicians to swap out worn inserts quickly and maintain consistent cutting performance. The tool’s design also supports the addition of T‑type extensions for extended reach in complex machining setups, providing flexibility for a variety of machining strategies.
