CoroMill Plura HD roughing end mill from Sandvik Coromant is for shoulder milling, full slot milling, and ramping and helical interpolation in steel and stainless steel. It can also be used with cast iron and heat-resistant materials. The tools offer secure and reliable machining in a wide range of cutting parameters.

High process security and long predictable tool life are essential in heavy roughing operations. CoroMill Plura HD's optimized flute shape was a result of the valuable insight gained from a Finite Element Analysis. The flute shape assures effective chip evacuation when machining a large depth of cut. The design also prevents re-cutting of chips and sudden tool breakage. By efficiently removing chips, full slot milling up to two times diameter with five-teeth end mills is possible without compromising process security. Internal coolant also promotes maximum chip evacuation and temperature control in stainless steel end mills.

The geometrical features and grades allow for exceptional metal removal rates and tool life. Two new grades have been developed; one for all-round conditions, preferably in dry machining, and one to deal with tough conditions and large engagements in wet machining. The tough face geometry was developed to cope with demanding ramping operations. Other features include differential pitch and cylindrical land to help minimize vibration and to provide predictable performance for reliable roughing.
