Description
Widin Carbide End Mill — Square Edge, 4-Flute, Extra Long Length (4 mm x 100 mm) — is a versatile cutting tool designed for high‑performance milling. Its square-edge tip and four-flute geometry deliver efficient material removal and precise results, with an extended reach that makes it ideal for tight pockets and detailed features on complex parts. The 4 mm diameter and 100 mm overall length provide the right balance of rigidity and accessibility for a wide range of applications.
- Deep-reach performance: The extra-long 100 mm length lets you mill deep pockets, through-holes, and hard-to-reach features in a single setup, reducing repositioning and improving accuracy.
- Square-edge with four-flute efficiency: Square cutting edges deliver clean 90-degree corners and strong shoulder cuts, while the four-flute design provides efficient material removal and a stable, smooth surface finish.
- Carbide durability you can rely on: Carbide construction offers exceptional hardness and wear resistance, maintaining sharpness for longer tool life and reducing downtime between tool changes.
This end mill is built to support busy workflows across professional shops and hobbyist setups alike. It helps you tackle deep, intricate features with confidence, maintain consistent tolerances, and finish parts faster thanks to reliable performance and extended tool life.
