About this app
The World's only app to help you calculate the cutting speed (RPM) for Annular Cutters and Magnetic Drills. This fully automated app can not only be used for BDS Maschinen GmbH products but also for products from other brands. This new RPM Calculator App can be used completely offline, independent of internet connectivity. This is how the App works...Select the model the magnetic drill you have, select the type of material you are drilling, select the type of annular cutter you are using, select the diameter of the annular cutter in millimeters or in inches and just press the Calculate button. Within a fraction of second, the App delivers the result informing you of the required cutting speed (RPM) for the size of the annular cutter as well as on which Gear you need to set your BDS Magnetic Drill.
