Cautions for machining with 8D holder Recommended machining 1 Make a center spot using DRA 3D/5D type or a commercially available center drill which has a vertex angle of about 140°. (Center spot should be at least half of cutting diameter) 2 Then drill the hole using DRA (8D type). J DRA 3D/5D 2 DRA 8D Center drill Applicable workpiece Not Recommended workpieces Applications Plain Surface Stacked Plates Concave Surface Pipe Material Shape of Workpiece Caution for machining 1.When machining stainless steel, for hole depths of up to 0.5D, keep feed rate at less than 0.15mm/rev 2.Internal coolant is recommended for smooth chip removal. For stainless steel, the combination of internal and external coolant is recommended. 1.Fix stacked plates securely to ensure they do not slip while machining. 1.When machining concave holes, set the feed rate at less than half of recommended feed for continuous hole machining. 2.Utilize a step feeding if chips are not broken short at the inlet. 1.Hole machining above the centerline of the pipe is possible. 2.Do not machine on curved surface areas.
