CHAMDRILL USER GUIDE Recommended Coolant Pressure and Flow Rate For special drills more than 8xD, it is recommended to use higher coolant pressure: 15-70 bar. To guarantee chip evacuation, the coolant must always flow through the tool. If the machine is not equipped with coolant through the spindle, we recommend using a coolant inducer. External coolant supply can Coolant Mix Recommended emulsion mix is 6-8%. When drilling in stainless and high strength steels, wa mix of 10% is recommended. When using the IDI drilling head, high pressure oil or 7-15% mineral or vegetable based oil emulsion is highly recommended for drilling stainless steel and high temperature alloys. Drilling Limitations be used if hole depth is less than 1xD and reduced cutting data is applied. The diagram shows the coolant flow rates for different drills and pressures. Dry Drilling It is possible to drill without coolant in cast iron. Oil mist through the drill is then required (for 2xD max). Regrinding of drill head is not recommended; it may cause drill malfunction. Centering Hole Data for DCM 8xD We strongly recommend the use of DCN 1.5D drill of the same diameter to drill a centering pre-hole. The use of the centering pre-hole improves hole location, accuracy, roundness, straightness and surface finish and reliability. Use internal coolant with at least 15 bar pressure.
