Drill diameter and depth of drilling Cuffing condition and kind of application Kind of workpiece and machine Drill bush Required machine power 0 I CL Straightness Drill diameter Depth of drilling Quantity of coolant Pressure of coolant 0. 5 "p Drill diameter The above graph shows general information and it is changeable depending on kind of tool, workpieces, and cutting conditions etc. Drill diameter .1 Pressure and quantity of coolant - High pressure of coolant ensures excellent chip evacuation and cooling the cutting edge. Use a filter for removing impurities - The diameter of a filter should be less than 20ym. Impurities could make bad flow of coolant, wear on a tool, and high load on the cooling pump. Temperature of coolant - Proper temperature of coolant 20°C 22°C / Do not use coolant at 50°C above Drills 84
