Description
The Widin Carbide Corner Radius End Mill is a high-performance tool designed for mold and die machining. Its variable index geometry, combined with a 4-flute design, delivers smooth cutting, efficient chip evacuation, and versatile performance across a range of corner radii.
With a 20mm diameter and a corner radius of 2mm (R2) and a long shank for deep groove work, this end mill is ideal for pockets, slots, and hard-to-reach features. A wide range of corner radii is available to match your part geometry and finish requirements.
- Variable index geometry: Distributes cutting edges to reduce cutting forces and improve chip evacuation, enabling smoother operation and longer tool life.
- 4-flute configuration: Balances strong material removal with reliable chip clearance for stable cuts and a consistent surface finish on mold and die features.
- Long shank for deep grooves: Provides extended reach for pockets, slots, and deep cavities, enhancing accessibility without sacrificing performance in challenging setups.
This end mill helps you accelerate production, minimize downtime, and achieve repeatable, high-quality results on complex mold and die geometries. The carbide construction delivers durability under demanding milling conditions, while the variable index and available corner radii let you tailor performance to each job—boosting efficiency from prototype through production.
