Sandvik Coromant Milling Tool Boosts Productivity in Steel Machining

Sandvik Coromant has launched a new milling concept — CoroMill MR80 — primarily designed for challenging roughing operations in a wide range of face and profile milling applications in steel and stainless steel.

CoroMill MR80 is a double-sided round insert concept with a higher number of inserts compared to regular round insert cutters. It is said to be ideally suited to low depth of cut — up to 3 mm — in face milling and profile milling applications in both steel and stainless steel.

Originally designed for machining cast stainless components such as turbochargers and exhaust manifolds in the automotive sector, this product has been further developed to cater to steel milling applications, which require the security of a round cutting edge — such as the die and mold segment. As a result, CoroMill MR80 offers both higher productivity and economical machining in a wide range of operations, with no compromise on security, according to the company.

CoroMill MR80 features double-sided inserts with 12 indexing possibilities when operated within a 3 mm depth of cut. A higher number of inserts on the cutter body also enables a higher table feed and increased productivity. Additionally, the overall security and reliability means less damage to the cutter body and inserts which, ultimately, helps cut costs.

Due to its lightweight cutting geometry, it is also possible to use CoroMill MR80 as a problem solver in difficult machining situations, even with long overhangs.

The CoroMill MR80 assortment offers cylindrical and arbor cutter bodies, with diameters from 32 to 100 mm, 3 to 12 cutting teeth and even pitch and shim protection. All cutter bodies feature internal coolant supply. The double-sided E-L50 inserts offer true and easy indexing (6 + 6), with a 3 mm recommended depth of cut.
