In Sandvik’s comprehensive range of CoroMill Plura mills, one will find their choice whether they need a tool that is optimised for a specific material or one that performs well in many materials. The range of tools includes high-performance solutions for high speed machining, die-making and high feed machining; from roughing to super-finishing in most materials, whether it is in difficult-to-cut materials or very hard steels, up to 63 HRc.

The benefits of CoroMill Plura are:

2-series: Tools with geometries and grades optimised for specific materials and applications, maximising production output per time unit.

Long tool life at high metal removal rate

1-series: Tools designed for high-performance and secure machining in a variety of applications, component sizes, shapes and materials, allowing maximum machine utilisation.

Flexibility – the same tool for many work piece materials

High machine utilisation thanks to few tool changes

Low downtime

The features are:

Solid end mills

Optimised grades for all materials and conditions

Cylindrical, Weldon and iLock shank options

Straight, conical, with and without chip-dividing cutting edge tool shapes

With and without neck, undersized shanks available

PCD tipped end mills with internal coolant

Thread milling cutters

Four grades optimised for different ISO material groups

Two different designs available depending on the application, one with few cutting edges and one multi-point design

Cylindrical and Weldon shank options

Individual radius programming (RPRG) value marked on the shank, giving the exact pitch diameter and radius correction required for optimum thread quality

CoroMill Plura has a large assortment for roughing to finishing and super-finishing.

Slotting: 50-degree helix, variable flute depth (VFD) tools for core stiffness and chip evacuation capabilities

Shoulder milling: Unequal helix concept for stability and excellent surface finish

Profiling: Wide range of ball nose end mills for all materials, including small cutter diameters down to 0.1 mm (0.004 inch), suitable for die and mould manufacturing where high precision is important

Chamfering: Tools for 45-degree and 60-degree chamfers and convex work piece radius chamfers

Thread milling: For both right- and left hand internal threads

Up to 3 × diameter

The threads are milled in one or more passes and the multi-point tool gives a true full profile 60-degree metric thread form.

Milling of composites

Compression end mills for composites

By combining positive and negative helix angles, the mill compresses the top and bottom of the component edge and thereby reduces the risk of splintering
