You can start from the lowest RPM and adjust it higher slowly. Once the bit can get into the workpiece, the adjustment should be stopped. Tapping/Threading Machine Recommended It’s highly recommended that the combination drill and tap bit is used on a tapping/threading machine or drill press. Avoid Shaking and Tilting If you apply an electric hand drilling machine to do the tapping job, please pay attention to your operating, because excessive shaking and tilting may affect the result and even break the bit. Use Cooling Liquid Keeping drills, taps and cutters cool and sharp. Cutting fluids or coolants will greatly increase the life of tap drill bits. Be Safe Always wear work gloves, safety goggles and protective clothing while doing any drilling job.
