Tungaloy Corp.’s MillQuadFeed series includes flat-top inserts with enhanced edge strength. These inserts come in two variations: the Z-type for versatile use and the U-type for small entry angles, providing improved durability and stable performance in challenging machining environments, such as interrupted cutting and machining of hardened materials.

The MillQuadFeed cutting tool combines low cutting resistance with high rigidity through its hybrid design, providing reliable performance in heavy-duty machining. It features a specialized insert geometry that is said to reduce cutting resistance by up to 20%, enhancing machining efficiency. Suitable for a wide range of applications such as shoulder milling and plunging, MillQuadFeed also provides double the tool life compared to conventional tools, according to the company.

Features of the MillQuadFeed series include:

• Chipping Resistance with Flat-Top Inserts: The flat-top design enhances the cutting edge, improving chipping resistance. Optimized negative land width and angle provide stable cutting performance. Reinforced corner radius provides high durability, even in high-load machining environments such as pocket milling.
• Inserts with Varying Entry Angles to Suit Different Applications: By adopting the optimized insert concept of the MillQuadFeed series, the tool is flexible and adaptable to various machining operations. The Z-type is suitable for machining where cutting depth is critical, reportedly achieving a cutting depth of APMX 1.5 mm for the 09 size and APMX 2.5 mm for the 15 size. The U-type, with its small entry angle, suppresses vibration during long overhang machining and extends tool life when machining high-hardness materials.
