Hoffmann Group 47 III 05 res si j&JGaiant‘ eco grooving GARANT eco system toolholders with internal coolant supply to the cutting edge. GARANT eco directs the coolant unerringly and efficiently. To use the coolant efficiently, the coolant stream must be directed optimally between the chip and cutting edge. With the innovative eco cooling technology, GARANT succeeded in significantly reducing the thermal loading, and in improving the chip formation process. GARANT eco allows higher productivity, longer tool life and thus fewer machine stops, better workpiece surface quality together with optimised predictability and better process reliability. Note: Coolant transfer available only in conjunction with GARANT eco-system VDI toolholders No.319001 -319191 or eco retrofit kit No. 317900. eco grooving toolholder with groove depth tm„ = 5xgroove width b Optimum cooling of the cutting edge with coo/ant. ensure reliable cool an t transfer.
