Cautions for installation on Machining Center

For installation of DRC type MagicDrill, use Hydro Chuck, Power Chuck, Collet Chuck, etc.
For side lock arbor, tool life is shortened due to drilling center deviation. Hole shape failure may occur.

                             Hydro Chuck

                             Collet Chuck                               Install MagicDrill to above chuck.

                             Power Chuck

                                                                                                                                                    Example of side lock arbor

Compared to competitor's drill A, MagicDrill DRC type has reduced burr and reduced more than                                    Compared to competitor's solid drill B, MagicDrill DRC type has greatly reduced preparation time with its easy insert
10% of the power required. Tool life has also improved greatly.                                                                 replacement feature. Also, the costs of spare tools for re-grinding has been reduced, and tool life has improved.

                        Q-1 Is re-grinding available?
                        A-1 We don’t recommended it. Grinding of edge nose chisel is not possible.
                        Q-2 How large would the cutting hole be to the insert diameter (Dc)?
                        A-2 The machining hole with SCM 435, comparing to the insert diameter (Dc , will be about +0.020~+0.040mm

                                    larger.
