The TN-300 pipe notcher from Baileigh Industrial is the best production hole saw notcher on the market today. This 110 volt notcher is built using only the best components. The idea of the TN-300 was to get rid of the hand drill and make a better tool for the fabricators. By building a rigid base and tying all the components together, we were able to reduce vibration created from the hole saw itself as it went through the material. Next we locked in the RPM of the saw to 177 rpm. This speed seemed to give the best combination of saw life and speed of cut. Both of these items helped make a more accurate cut and increase the life of the saws, saving time and money.
