CMT ORANGE TOOLS 552 540 Cup Saw Dia for Stoneware/Marble/Granite S=M14 D=40x15/40x60 DX

Diamond Holesaws 552-5 Dry Use for Grinder RPM 14000 Max. Recommendations for use: Start drilling (with the tool already rotated) at an angle of about 30° between the hole saw and the plane, in this way you will avoid slipping of the tool and you will achieve a more precise centering (at this stage put the machine on the floor for more stability). Continue drilling vertically but accompanying the tool with an orbital motion that promotes cooling and evacuation of the processed material (if using the guide start drilling vertically, then take it off and continue orbitally). Remember that this is not a drill bit but a cutter, so perfectly perpendicular drilling will greatly reduce the life of the tool. Water cooling can increase tool life. SUGGESTED RPM? High RPM values reduce the chance of damaging / burning the diamond crown, ensuring a longer service life. Turn off the impact mechanism.
