Step-drill from Lothmann

Stufenbohrer von Lothmann

One tool to accurately complete drilling, boring, turning and milling operations: Step-drills from Lothmann

Lothmann special tools combine as many metal machining operations as possible and practical, including drilling, boring, counter-sinking and chamfering, and back-boring and back-chamfering; in some cases even the milling of thinner sheet materials, all in one tool. Using customer-specified requirements, we combine the appropriate cutting insert geometries, standard tool shank designs and other details, and design and build a customer-specific special tool in the shortest time. Carbide inserts can be used on a variety of materials: steel, cast iron, stainless steel, Aluminum and other non-ferrous materials.

Producing our Step-drills

Our step-drills are produced using our CAD-CAM process. Special milling operations can first be simulated in 3D-CAD. The tricky positioning of coolant-through channels is aided by CAD-CAM and a 100% functionality is assured.

The machining of our tools is done using our CAM process and is therefore very accurate. Carbide inserts used have a very high tool life and temperature stability. Carbide inserts are accurate and reliable, an important advantage compared with HSS tools. Our step-drills and other tools are surface hardened, finish ground and finally cutting inserts are installed. This eliminates any tool resharpening.
