Widin Carbide Corner Radius End Mill — a precision milling tool built for CNC professionals who demand clean corners, tight tolerances, and dependable performance. This 4-flute, stub-cut end mill is designed to deliver consistent results in demanding machining tasks.

• Diameter: 4 mm
• Overall length: 50 mm
• Corner radius: R0.5
• Flute count: 4-flute design
• Cutting length: Stub-cut length for enhanced rigidity in confined spaces
• Cutting geometry: Straight flute to improve rigidity and minimize corner damage
• Edge type: Back Draft Type cutting edge reduces chatter and movement
• Material: Carbide for high hardness, wear resistance, and long tool life

This end mill excels in precision milling tasks where stability matters most—pocketing, contouring, and finishing fillets with minimal deflection. The straight flute combined with the stub-length design helps maintain accuracy during deep cuts, while the back-draft edge smooths cutting forces to produce cleaner surfaces and tighter tolerances. The 0.5 mm corner radius offers a practical balance between corner strength and finish quality, helping prevent premature tool wear and edge burrs. With a robust carbide construction, you can expect durable performance across multiple workpieces and setups.
