A4™ • Double-Ended Grooving
Maximize your machining capabilities with Kennametal's A4™ double-ended grooving solutions. These cutting-edge tools offer a versatile range of inserts, boring bars, modular tooling, and toolholders to meet the demands of several operations. With the A4™ series, you can streamline your operations by using a single tool for turning, facing, grooving, and face grooving in both Outer Diameter (O.D.) and Inner Diameter (I.D.) applications. The A4 series eliminates the need for frequent turret indexes, resulting in exceptionally fast cycle times. The system offers an extra-long clamping area, a precision-ground 120° bottom prism seating surface, and an exclusive top guide rail. These features work in harmony to provide unparalleled stability during grooving and side-turning operations, ensuring precise insert positioning and delivering accurate cuts. When it comes to optimizing your machining capabilities, Kennametal's A4™ double-ended grooving tools provide the solutions you need.
