Tungsten Carbide Grit Drilling Tips

Tips for using the ARTU Tungsten Carbide Grit Hole Saw

  1. Drill the pilot hole before attaching the hole saw to the arbor.
  2. Place hole saw on the arbor with grit edge against the material to be cut.
    Using a clockwise rotation of the saw will lock the unit to the arbor.
  3. To get the hole saw to work more effectively, scratch the surface of the material to cut by using a slight rocking motion of the drill motor.
  4. When cutting deep holes, pull the hole saw out of the hole from time to time to clear away any material debris.
  5. Use of a high powered 1/2" drill motor is recommended, especially with the larger size (3-1/4" or 4") hole saws.
  6. If your drill motor has a support handle, use it for extra leverage.
  7. Once the hole is cut, the plug can be easily removed by detaching the hole saw from the arbor. (CAUTION! The saw will get hot!)
  8. For holes deeper than 2-1/4": drill a pilot hole with a bit long enough to go all the way through the material. Then, proceed with the hole saw to make desired hole.
  9. When using the 8- and 9-piece hole saw sets on materials deeper than 2-1/4", you must start drilling from one side of the material and then switch to the other side of the material to finish the hole.
