RF 100 Diver with internal cooling optimised for drilling and milling

Programme extension for ramping, drilling, slotting, roughing & finishing

RF 100 Diver has established itself with customers that require high flexibility. The Ratio end mill covers five operations with one tool: It can perform drilling, ramping, slotting, roughing and finishing operations. As well as a programme extension Guhring is now introducing an innovation in the coolant delivery sector: Internal cooling optimised for both milling and drilling. 

Where drilling tools rely on axial coolant ducts and milling tools on radial coolant ducts, RF 100 Diver offers both, in order to optimally cool and protect the face as well as the circumference geometry when drilling and plunging. Guhring’s decades of know-how in the production of carbide as well as FEM optimisation ensure maximum efficiency in cooling lubrication, chip evacuation and tool stability.
