Bit/ Cutter/Cutting Tool /Interchangeable Insert Drilling System with Internal Cooling

MULTIPLEX - THE VERSATILE ALTERNATIVE:
The interchangeable insert drilling system with internal cooling for especially high performance machining, for hole diameters from 10.0 to 260 mm.

The most important system advantages
• No re-grinding and re-coating costs. Only the insert is replaced.
• Quick insert change: Simply loosen two screws, remove worn insert, insert new blade, tighten screws - finished.
• Variable tool material, variable coating.
• Constant tool length, resulting in reduction of set-up time and therefore set-up costs. Pre-set-up time and re-setting no longer necessary with CNC machines and automatics.
• High performance machining and optimal tool life thanks to internal cooling and wear resistant inserts.
• Reduced storage costs because one holder can be applied for several insert diameters.
The holder range
All holders offer internal coolant delivery. It ensures the coolant is transported directly to the cutting edges and provides total efficiency. Even high cutting rates are not a problem for the inserts. In addition, the internal cooling ensures optimal chip evacuation by washing the swarf out of the drilled hole thereby making the time consuming peckfeeding unnecessary.
The straight shank holders are available in the following lengths:
• short, for drilling depths 3 x D
• long, for drilling depths 5 x D
• extra long for drilling depths 7 x D
• extra length for drilling depths up to 20 x D
• modular drilling system with variable drilling depths (because of changeable extensions) Standard taper and straight shank holders are hardened, nickel-plated and possess an optimised flute profile (<35 mm Ø) providing improved quality and chip evacuation.
Application example: Drilling into the solid with Ø 260.00 mm in material 34 CrNiMo with 1000 N/mm2
Step drill for the efficient:
