Widia offers two insert families specifically designed for high-feed milling: the M270 series and M370 series.
The M270HF inserts are designed based on the company’s X-Feed geometry. Two contact faces in a V-shaped pocket design ensure secure insert clamping and accurate insert positioning to improve cutting performance and tool life. Three grades are available: TN2505 for wear-resistance in materials ranging to 60 HRc; TN6540 for added toughness; and TN6525 for dry-machining applications in steel.
The M370 series is a double-sided, high-feed concept that combines insert technology with performance and reliability for steel and cast iron milling. Designed for high-feed-rate productivity, its double-sided concept and six cutting edges provide security and optimized metal removal with an efficient cost per edge. It is suitable for machining stainless steels and titanium.
Both series are available in inch and metric sizes.
