Guide Drilling should be done asDiameter+0.1mm between 3xD and 5xD depth.2. For Main Drilling, proceed with low RPM at GuideDrilling segment.(RPM 300, FEED 400mm/min)3. Just before the end of Guide Drilling segment,reduce feed to zero and increase the RPMaccording to Recommended Cutting Conditionchart (See above).4. After then, proceed main drilling by increasingfeed without step drilling.5. When coming out from Guide Drilling start pointafter drilling, RPM should be reduced as 300 andfeed should be 1000 mm/min.6. When coming out from Guide Drilling segment tothe outside, the feed should be decreased as50%.CENTERDRILLSSPADEDRILLSTECHNICALDATA78• phone:+82-32-526-0909, fax:+82-32-526-4373, www.yg1.kr, E-mail:yg1@yg1.kr
