Description
The Widin Carbide Corner Radius End Mill is a precision tool designed for mold and die work, built around a variable index and a four-flute design to tackle a range of milling tasks with reliability. Sized for 4 mm diameter work, it features a corner radius of 0.3 mm (R0.3) to produce clean, accurate corners while delivering versatile performance across contouring, pocketing, and deep-groove applications.
Its long shank provides extended reach for deep grooves and tight spaces, allowing you to machine in challenging locations without repositioning the work or changing setups. The variable index geometry evenly distributes cutting edges, lowering peak cutting forces and improving chip evacuation for smoother, more efficient milling operations.
- Variable Index Geometry for Smoother Cutting and Efficient Chip Evacuation: Distributes the cutting load across edges to lower peak forces and channels chips away from the cut for smoother finishes and reduced heat buildup.
- 4-Flute Design for Robust Material Removal and Consistent Finishes: Higher chip-carrying capacity with stable, controllable cuts, enabling efficient material removal while maintaining a clean surface finish.
- Long Shank for Deep Groove Access and Flexible Reach: Extended reach lets you access deep pockets and grooves without reworking fixtures, improving productivity and setup flexibility.
This end mill is designed to help mold and die projects move from roughing to finishing more efficiently, with reliable performance across a range of corner radii. The combination of variable index, four flutes, and a long reach supports consistent results, reduced downtime, and greater flexibility in how you approach complex features.
