Meet the ITC Carbide End Mill Square Edge 3091—a 20 mm diameter, 3-flute carbide end mill designed for high-performance machining in non-ferrous materials. It combines a square edge with a 38° helix and a trace of land to deliver stable cutting, efficient chip evacuation, and a cleaner surface finish.
- Efficient chip evacuation and stable cutting: The 3-flute geometry together with a 38° helix promotes smooth chip flow and steady, vibration‑free cutting for reliable performance across a range of feeds and speeds.
- Trace of land for superior surface finish: This feature helps achieve cleaner edges and tighter tolerances by enhancing surface quality during finishing passes on non-ferrous metals.
- Durable carbide construction for non-ferrous use: Built from hard, wear‑resistant carbide, the 3091 maintains sharpness and delivers consistent results through repeated milling operations.
Designed for professionals, engineers, and skilled hobbyists who demand precision and reliability, this end mill helps you reduce rework, improve cycle times, and achieve repeatable finishes—pass after pass, in non-ferrous materials.
