The Widin Carbide Corner Radius End Mill is a precision cutting tool designed for micro-machining tasks that demand exact corner radii, deep grooves, and carefully sloped surfaces. Built for engineers, hobbyists, and shops seeking reliable accuracy, it features a tapered neck to boost stability across challenging cuts.

• Diameter: 0.4 mm cutting diameter for precise, fine-detail milling
• Neck Type: Tapered neck design to reduce vibration and chatter during operation
• Neck Length: 4 mm reach for deeper grooves and tighter geometries
• Corner Radius: R0.5 mm corner radius for clean, accurate fillets
• Flute Count: 2-flute geometry balances material removal with a smooth finish
• Material: Solid carbide for exceptional hardness and wear resistance
• Application Focus: Optimized for deep grooves and sloped surfaces with reinforced corner-radius integrity

The combination of a small 0.4 mm cutting diameter and a durable carbide construction enables high-precision work in tight spaces, from intricate pocketing to precise filleting on challenging materials. The tapered neck reduces tool vibration and chatter, preserving both surface quality and dimensional accuracy over longer cutting sequences. The reinforced corner radius helps resist chipping at delicate corners, delivering consistent passes and predictable results across multiple operations. Whether you're finishing microfeatures on a precision housing, shaping tight fillets on a miniature component, or carving recessed grooves, this end mill provides the stability and control you need to achieve reliable, repeatable results.
