Applications

The solid carbide drill mill BNF RT340 is excellently suited for versatile drilling and milling tasks across a wide range of industries. With its 5-in-1 capability, it masters countersinking, spot drilling, chamfering, V-grooving, and general milling applications. It is a reliable choice for machining unalloyed to high-alloyed steel, stainless steel, and both wrought and cast aluminum alloys.

Special features

Featuring the wear-resistant PVD coating RT340 applied to fine-grain carbide, this drill mill offers excellent thermal stability for various materials. The cylindrical shank ensures secure clamping in the machine, while the two flutes and 30° helix angle promote effective chip evacuation. The 90° included angle enables clean and precise results, and its multifunctionality significantly minimizes downtime by reducing the need for frequent tool changes.
