Rannb Square End Mill 3/8″ Dia x 3/8″ Shank 4 Flute Cutter 2pcs

Description

Product Overview

The Rannb Square End Mill is engineered for precision machining across a broad spectrum of industrial applications. Constructed from high speed steel (HSS), the cutter offers exceptional hardness, wear resistance, and longevity even under demanding cutting conditions. With a 3/8″ (9.5 mm) cutting diameter that matches a 3/8″ shank, the tool provides seamless compatibility with standard collet sizes, eliminating the need for additional adapters. Its four‑flute configuration creates a large front angle that effectively reduces cutting resistance, allowing smoother chip evacuation and higher material removal rates. The overall length of 2‑3/4″ (69 mm) and a maximum cutting depth of 1″ (25 mm) give users flexibility for both shallow and deep cuts. The package includes two identical end mills, each individually boxed for protection during storage and transport, ensuring that you receive a ready‑to‑use set for immediate production.

Usage

Designed for side milling, end milling, and finish machining, this square nose cutter excels when working with carbon steel, alloy steel, die steel, tool steel, cast iron, and even titanium alloys. The robust HSS material tolerates high spindle speeds while maintaining dimensional stability, making it suitable for CNC milling centers as well as manual milling machines. Whether you are fabricating aerospace components, automotive parts, or precision tooling, the cutter’s geometry delivers a clean, square profile that minimizes burr formation and reduces post‑processing time. Its efficient chip removal capability also helps maintain lower temperatures, extending tool life during prolonged production runs. The 2‑piece set is ideal for batch operations where one cutter can be used as a backup while the other remains in service, ensuring uninterrupted workflow on the shop floor.
