The through coolant holes supplies constant coolant flow to the tip, For small diameters, an additional power chamber in the shank assures a higher flowrate than our competitors. Comparatity at the same coolant pressure three times the flow rate will be supplied to the cutting edge. This technology enables high drilling speed with more effective chip removal. High performance eXedur RI / RIP coating provides therma and wear protection, guaranteeing a longer tool life.
For the version with drilling depths up to 6 x d centreing is not necessary on straight surfaces, with its tip angle of 140 deg and its chisel "s" - form the drill has good self centreing . We recommend pilot drilling or centreing on irregular surfaces , rough or inclined surfaces and if a high position accuracy is requested.
