Pilot holes are always necessary for drilling depths over 7 x D:1.Thepilotholecanbeproducedwithashort,rigiddrill.Thediametershould

be0.01-0.02mmlargerthanthediameteroftheRatiodrill.Drillingdepth≥1xD.

2.Alternatively,theRatioDrillscanproducetheirownpilothole.Cuttingspeedandfeedratemustthereforebereducedby30-40%.

3. Acoolantpressureof40barisrecommended.

For safety reasons it is very important, that a drill doesnot exceed a speed of n = 6 000 rev./min when not supported.The centrifugal forces could break these long tools beforereaching the workpiece surface!
