Minimum Coolant Pressure (bar) 15 12 10 8 5 3 6 12 16 20 25 Drill Diameter D (mm) For optimal performance, it is recommended to adjust runout of outer points or chisel with a maximum of 0.02 mm. Large runout will influence drill performance tool life and hole quality. No setup time is needed after indexing the SUMOCHAM drill head. SUMOCHAM drills can be used either on milling centers or lathe machines. When using SUMOCHAM drill in stationary (lathe) applications, we recommend using the ISCAR GYRO device or eccenter sleeve to reduce misalignment. Misalignment will cause poor performance of the SUMOCHAM drill or even tool breakage. 1 Pre-hole 0.5xD deep for centering 2 Slow rotation and feed while entering to the pre-hole 3 Maintain for 2-3 seconds and activate the cooling system 4 Continue drilling at recommended cutting conditions Prior to using 8xD or 12xD drills, it is recommended to drill a 0.5xD pre-hole using a short or centering drill. Enter the pre-hole at slow speed and feed until 2-5 mm from its bottom. Start the cooling system and increase rotation to recommended drilling speed.
