MagicDrill DRC Flanged shank SF Coolant 1. Internal coolant is recommended. 2. In case of using external coolant system 3. Dry machining is not recommended. In case of horizontal M/C Lathe: 3D or less Vertical M/C: 1.5D or less K Internal coolant is recommended for horizontal machining center because external coolant may not sufficiently be applied to inside because the tool is revolving. Precautions for use Core deviation 1. If drill is stationary 2. If drill is rotating max. 0.02mm max. 0.02mm This can be used with a boring sleeve (Screw clamp) and collet chuck, Make sure to use arbor that is not deformed. please be sure to set deviation amount within 0.02mm between workpiece and drill. Center of arbor deviation must be within 0.02mm. Cautions for installation on machining center For installation of Magic Drill DRC, 1st choice hydro chuck, power chuck, collet chuck, etc. 2nd choice side lock arbor Hydro chuck Power chuck Install Magic Drill DRC to the chucks Collet chuck Example of side lock arbor 2nd choice K42 Drilling
