Cutting tool specialist Sandvik Coromant announces the launch of CoroMill® Plura composite 2P350 with the new diamond-coated grade O2AD, setting a new performance benchmark for milling operations in abrasive composite materials. Engineered for ISO O workpiece materials, this upgraded tool delivers significant gains in productivity, tool life and process security.
Composite machining has long presented challenges such as delamination, uncut fibres, vibration and rapid tool wear. CoroMill® Plura composite 2P350 directly addresses these issues through its patented dual-cutting mechanism, which provides a controlled, scissor-like cutting action for stable and predictable machining.
The new O2AD grade is engineered to withstand the abrasiveness of composite materials. The strong adhesion between the CVD diamond coating and the tailored substrate ensures best-in-class performance and consistency. Field tests show up to +100% longer tool life compared to the previous O12M grade.
“CoroMill® Plura composite 2P350 is designed to solve the most common challenges in composite machining, including rapid wear and unpredictable performance caused by abrasive and heat-sensitive materials,” says Liam Haglington, Product Manager for solid carbide end milling tools at Sandvik Coromant. “Component quality is critical, and issues like delamination and uncut fibres can compromise the integrity and quality.”
CoroMill® Plura composite 2P350 supports a wide range of demanding composite applications, including slotting, ramping and edging. Its large flute volume enables efficient chip evacuation and high material removal rates, while its low vibration cutting behaviour contributes to a more comfortable sound environment on the shop floor.
Aerospace manufacturers producing fuselage structures, wings, stabilizers, spars, ribs and frames can expect substantial improvements in both part quality and productivity. The tool also offers clear performance benefits for industries such as automotive, defence, space and nautics.
“One of the most consistent pieces of feedback we receive about this tool is that it just works, no matter the machining conditions, workpiece holding, or tool holding,” Haglington continues. “If you’re looking for safe, consistent, and high-performance composite machining, CoroMill® Plura composite 2P350 delivers at every level.”
