The Widin Carbide Corner Radius End Mill for Mold & Die is a precision cutting tool designed to meet the exacting needs of mold and die work. It features a 2-flute configuration and a tapered neck to reduce vibration and chatter, delivering smoother, more precise cuts even in deep grooves.

Sized for tight spaces, this tool measures 4 mm in diameter and 40 mm in length, with a corner radius of 0.2 mm, and is offered as a 1-piece assembly. The carbide construction provides the rigidity and wear resistance required for demanding production environments, making it a reliable choice for both professional machinists and dedicated hobbyists.

• 2‑Flute design with tapered neck: Reduces vibration and chatter to maintain stable cutting, improving surface finish and dimensional accuracy in deep groove milling.
• Corner radius R0.2 mm for clean, precise corners: Delivers accurate fillets on mold and die cavities without sacrificing material removal efficiency, ensuring reliable, repeatable results.
• 4 mm x 40 mm, 1-piece carbide construction for rigidity: Provides strong rigidity and long tool life in a compact form, enabling consistent performance in tight spaces and demanding materials.

This end mill helps you finish molds and dies with tighter tolerances, fewer reworks, and faster cycles. Its combination of vibration control, precise corner geometry, and durable carbide construction supports reliable, repeatable results across a range of applications—from detailed inserts to deep groove features—so you can complete projects with confidence and efficiency.
