MagicDrill DRC Flanged shank SF Applicable workpieces Applications Shape ofworkpiece Caution for machining 1. Due to good chip control, step machining is not necessary for low carbon steel. Plain surface 2. When machining SUS304, for hole depths of more than 2.5D, utilize the step machiningprocess. 3. In order to have smooth chip removal, we recommend internal coolant. 1. Fix stacked plates securely to ensure so that they do not slip while machining. Stacked plates 1. If the overlap amount is 1/3 x DC or less, Original hole Next hole machining is possible. Hole expansion DC 1/3 x DC or less 1. When machining concave holes, set the feed rates at Concave surface half or less than continuous hole machining. K 1. Hole machining above the centerline of the Pipe material pipe is possible. 2. Do not machine on curved surface areas.
