Excellent value – set of 3 step-drills and a 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 Mocap or ‘bung’ fits neatly and securely.
I have used much more expensive variants … and yes they might last a ‘wee’ bit longer than these units …. but not that much longer. I find these ones are by far the better value.
3 drill bits if different (overlapping) sizes; 4-12mm, 4-20mm and 4-32mm
- High Speed Steel
- 1/4″ shank
- Centre Punch
