Don't cut holes in your bodywork with holesaws or step drills, use one of these. Why hack when you can punch? The neatest, most professional holes in flat sheet material you can make.
To use: Drill a pilot hole for the central bolt. Assemble the punch on both sides of the sheet then tighten the bolt with a hex wrench. A few seconds later you will have a perfect hole with no distortion*. For large 'squoval' apertures punch a hole at each corner and cut the centre out.
What's special about ours? We supply them with miniature roller thrust bearings to go under the bolt head and make cutting even easier!
*Please note that there will be some slight distortion if your panel isn't completely flat but it easily dollies out and it's still far less distortion than using a holesaw!
