Somta Somta Series 316 - 20.0 mm HSS-Co8 Roughing End Mills

Somta Series 316 – 20.0 mm HSS-Co8 Multi-Flute Roughing End Mill | 3162000

The SOMTA 3162000 is a high-performance HSS-Co8 roughing end mill engineered for aggressive material removal and high-feed profiling. Designed with a 4-flute geometry and a durable TiAlN coating, it provides exceptional wear resistance, heat stability, and tool life. The centre-cutting design ensures smooth plunging and contour milling, making it ideal for both manual and CNC machining of steels, cast irons, and high-tensile alloys.

• HSS-Co8 Material – Offers superior hot hardness and edge strength under demanding conditions.
• TiAlN Coating – Increases oxidation resistance and extends tool life at elevated temperatures.
• 4 Flutes – Ensures efficient chip evacuation and balanced cutting at high feed rates.
• Centre-Cut Design – Allows direct plunge cutting and slot milling.
• High-Feed Roughing Geometry – Enables rapid stock removal while maintaining dimensional accuracy.
