Ask a Question
  • I'm looking for a 177mm hole saw to cut into a steel pipe thickness 10mm and the hole saw needs to be 80mm long Thank you

    We do have a 177mm hole saw, however the length of the saw is 40mm without the arbor attached.

  • At what speed must I run a 32 mm steel hole saw, in a drill press?

    For cutting mild steel 275 RPM is the ideal speed

  • what size will the inside circle be with your 83mm hole saw?

    It will be 79mm

  • what is the meaning of the "life rating 20x" inscription on the industrial metal drill bit package?

    The life ratings are to help distinguish our drill bits from each other by giving an indication of how much work you can expect from each.
    For example, in similar working conditions you can expect to drill 10 times as many holes with an Industrial Metal bit (20x life rating) as with a Standard Metal bit (2x life rating)
