I am attempting to use a drill press to drill a 13mm hole in the ends of a small electronics enclosures (a Hammond case). The wall of the case is about 2mm thick and made of ABS plastic.
Started off by drilling a 5mm pilot hole and followed it up carefully and slowly with the 13mm bit. Immediately the box was grabbed by the bit and the workpiece was ruined (split down the side). After massaging my bruised thumb I realised that I need a better way to do this.
Reckon I'd have no better luck with a hand-cranked drill or a cordless drill.
My available tools are severely limited and there's no hope of getting any budget to buy new tools (not for a small project like this). I've got a decent selection of drill bits and a small, fixed-speed drill press and not much else.
I did consider just drilling a 5mm hole and simply reaming it up to the 15mm hole we actually need but this is a real pain in the neck.
What can I do to prevent this grabbing problem?
