Step Drills (Pk 3) Plus Centre Punch


Excellent value set of 3 step drills and an automatic centre punch.

These are inexpensive step drills – great for drilling test points in galvanised ducting with no burs …. and no need for a pilot hole.  Accurate drilling using the centre-punch which ensures the selected blind grommet or ‘bung’ fits neatly and securely.

I have used much more expensive variants … and yes they last a bit longer than these units …. but not that much longer and I find these ones are certainly the better value.

3 drill bits if different (overlapping) sizes;  4-12mm, 4-20mm and 4-32mm

  • High Speed Steel
  • 1/4″ shank
  • Automatic Centre Punch
