PCD combination tools PCD STEP REAMER/MILL PCD STEP DRILL/REAMER › FEATURES A specially designed PCD insert and flute geometry combining several operations in one tool. Ensures a vibration -free finishing of all valve bore diameters in one pass, creates different surface roughness values within a specified range and a T-groove geometry. › BENEFIT Reduced overall cycle time with the multi tasking tool design due to reduction of tool changes and number of tools necessary. › CUTTING DATA EXAMPLE n = 3000 RPM, fn = 0.2-0.3 mm/rev. › FEATURES A special 2-fluted tool design for the shrink fit holder system. First step is drilling in solid material and the remaining steps are reaming pre-casted material. Internal coolant channel design for improved chip evacuation. › BENEFIT One-shot solution, reduced overall cycle time, less tool changes, fewer tools in operation. › CUTTING DATA EXAMPLE n = 6500 RPM, fn = 0.3-0.4 mm/rev. 8
