3 Technical information Power requirements The guide values are for drilling alloyed steel N/mm and can vary for other workpiece materials and tool conditions (wear). Spindle Power (kw) , , , f=0,5 (mm/u) f=0, (mm/u) f=0,16 (mm/u) f=0,4 (mm/u) f=0,3 (mm/u) Feed Force (kn) f=0,4 (mm/u) f=0,3 (mm/u) f=0,5 (mm/u) f=0, (mm/u) f=0,16 (mm/u) Coolant values Suffi cient coolant must be supplied to the tool for troublefree chip removal Coolant Flow (l/min) Coolant Pressure (bar) , Cutting data Guide values for cutting speed and feed rate are shown in the table. As there are many factors that can affect the results of deep hole drilling, these values must be correted if necessary.
