2 Flute Corner Rounding End Mill Rannb 0.1″/2.5mm Radius 0.4″ Shank

Description

Product Overview

The Rannb 2 Flute Corner Rounding End Mill is engineered from premium high speed steel (HSS) to provide a balance of hardness, toughness, and wear resistance that meets the demanding requirements of modern CNC machining environments. With a precise 0.1 inch (2.5 mm) radius and a robust 0.4 inch (10 mm) shank, this tool is designed to create smooth, rounded corners on a variety of workpieces, reducing stress concentrations and improving part performance. The tool features a 0.24 inch (6 mm) head diameter and a total length of 62 mm (2.44 inch), offering a compact profile that fits easily into standard tool holders while delivering consistent material removal rates. Its form‑relieved geometry allows for repeated sharpening without altering the cutting profile, extending tool life and reducing overall operational costs. The end mill is compatible with both ferrous and non‑ferrous materials, making it a versatile addition to any machining toolkit.

Usage

Designed for precision CNC milling, the Rannb corner rounding end mill excels in applications where tight radii and clean transitions are essential. Typical use cases include aerospace component fabrication, automotive part machining, medical device manufacturing, and tooling for molds and dies. The tool’s high speed steel construction enables it to maintain cutting performance at elevated spindle speeds, while the 0.4 inch shank ensures stable engagement with the machine spindle, minimizing vibration and chatter. Users can employ the mill in both roughing and finishing passes, taking advantage of its ability to create smooth, deburred edges that reduce post‑processing time. The end mill is also suitable for re‑sharpening on standard grinding equipment, allowing shops to recycle the tool and maintain consistent geometry across multiple production runs.
