Performance

Our end mills have the best material removal rates on the market, while reducing the forces the tool must endure. The resulting chips are of optimal geometry, clearly scored and perfectly projected. The low noise level provides excellent vibration control. By working in partnership with our advanced materials research centre, PIRANHA has been able to create a line of innovative, high-performance products, thereby optimizing the cost per part produced in its customers’ manufacturing processes.
