Boring Tools

Precision Cutting Tools has improved it’s 360 series endmill for 2019. The design consists of the eccentric OD, a sharp corner, a larger gullet and a ground 1° radial land. The series increases metal-removal rates and minimizes chatter. The endmill is ideal for aluminum milling applications. This tool also comes standard with our PVD Diamond Coating, Exxtral Carbon, for up to 3 times more tool life. All these characteristics lead to improved accuracy, higher speeds and feeds, machining longer DOC and superior surface finishes.

Modern CNC machines, regardless of their sophistication, cannot automatically compensate a boring tools cutting edge.

The Zenith system integrates ActiveEdge tools with in-process gauging to enable a machine controller to automatically compensate for insert wear, temperature changes and material inconsistency without manual intervention and without stopping the manufacturing process.

KenTIP FS is suitable for many challenging operations. Chain hole drilling in steel is one of them. While KenTIP FS has four coolant holes — two at the tip and two in the chip gullet directly behind the head — the HPG geometry comes without front coolant holes. When drilling in steel it's important to concentrate on coolant delivery to the rake and take the heat from the contact zone between chip and rake surface. The new HPG geometry is especially designed for steel, and comes in the hew, highly wear resistant grade KCP15A.

Nick Gaten, director of global product management for turning products at Kennametal Inc., discusses the new 10-to-1 boring bar system. It features vibration-free boring bars with bolt-on heads.
