Drill bit for Acryllic

Posted by Cian O'Reilly on 26 August 2010 at 08:40

Hi,

I will be drilling 5mm holes into 4mm clear acryllic. I need a advice on which drill bit to use (wood,metal,any specific?) so to not break the sheets or melt around the edges. Any other tips would be appreciated.

Thanks

A normal metal bit is fine, make sure it is sharp so it doesn’t melt the acrylic. Make sure you drill onto a sacrificial board to prevent splitting.
You will find that cast acrylic is a lot better than extruded.

I’m firmly in the SHARP drill & sacrificial material camp.
