ITC Carbide End Mill Corner Radius 4061 - 4 Flute 30° Helix With Roll Relief, Radius & Coating - General Purpose - 16mm x R0.25

The ITC Carbide End Mill Corner Radius 4061 is a general‑purpose cutting tool designed for engineers, machinists, buyers, and hobbyists who need reliable performance across roughing and finishing tasks. It features a 16 mm cutting diameter, a 0.25 mm corner radius (R0.25), a 4‑flute design, and a 30° helix to balance material removal with edge quality.

Designed for broad compatibility, this end mill incorporates roll relief and a specialized coating to reduce cutting forces, improve stability, and extend tool life. These features help maintain consistent results across a variety of materials and workpieces, even during demanding operations.

• Efficient chip evacuation and stable cuts: The 30° helix combined with roll relief promotes smooth chip flow, reduces vibration, and lowers cutting forces for cleaner surfaces and steadier performance during both roughing and finishing.
• Precise corner radius for durable edges: The R0.25 corner radius delivers consistent, accurate corners and fillets, minimizing stress concentrations and enhancing part quality over many cycles.
• Coated carbide for extended tool life: The hardened carbide substrate with a purpose-built coating delivers improved wear resistance and heat tolerance, helping you achieve longer tool life and more predictable results.

This end mill supports efficient workflows by delivering reliable, repeatable results across a broad range of materials. Its robust construction and coating are designed to reduce downtime from tool changes, maintain tight tolerances, and help you achieve smooth finishes with confidence, whether you’re prototyping, producing in high volume, or performing routine maintenance on varied workpieces.
