ITC Carbide End Mill Square Edge 4631 - 4 Flute 30° Helix With Facet Relief - General Purpose - 5mm

The ITC Carbide End Mill Square Edge 4631 is a 5 mm diameter carbide end mill designed for general‑purpose machining. Featuring a square edge, four flutes, a 30° helix, and facet relief, it delivers efficient chip evacuation, lower cutting forces, and stable cutting performance across a variety of materials.

Ideal for engineers, machinists, hobbyists, and technicians who value precision and reliability, this end mill is ready for everyday milling tasks—from light finishing passes to more aggressive roughing operations.

• Four‑flute rigidity for stable cutting: The four‑flute design increases tool rigidity, helping maintain consistent feeds and delivering cleaner finishes during both roughing and finishing passes.
• 30° helix with facet relief for smooth cutting: The angled flutes optimize chip flow and reduce rubbing, lowering cutting forces and extending tool life through steadier, quieter operation.
• Square‑edge carbide for general purpose versatility: A robust carbide construction with a square cutting edge provides reliable performance across a wide range of materials and everyday milling tasks.

This end mill supports faster setup, fewer interruptions, and more consistent results in production and prototyping workflows. With durable construction and proven geometry, you can trust it to deliver reliable performance pass after pass for general‑purpose milling projects.
