Description
The Widin Carbide Corner Radius End Mill is a precision cutting tool designed for stainless steel and exotic alloys. Featuring a 12 mm diameter and a 1.0 mm corner radius, it enables precise contouring and clean, repeatable edges on complex profiles. Its 4-flute design and variable helix promote steady cutting and reliable chip evacuation, even in demanding materials.
- Efficient Chip Evacuation: The 4-flute geometry paired with a variable helix enhances chip removal and reduces heat buildup, helping maintain smooth cuts and consistent performance.
- Corner Radius for Precise Contouring: The 1.0 mm radius supports accurate contouring while minimizing chipping or fracture, leading to superior edge quality and dimensional stability.
- Durable Carbide Construction with Long Tool Life: Hardened carbide offers excellent wear resistance in stainless and exotic alloys, delivering lasting tool life and dependable cutting performance.
This end mill supports efficient workflows and consistent results by delivering reliable finishes with fewer passes. Its robust construction and stable cutting action help reduce downtime, improve surface quality, and empower you to tackle challenging milling tasks with confidence.
