Beck's Tip
My daughter, the would be jeweller, told me this one.
When faced with drilling a large or not so large number of small holes in thin metal, she uses balsa wood as a backing. The balsa is weak enough not to deflect and break small drills ( in Beck's case, sub 1mm ) as does a harder timber when the drill seeks out a nearby hole. Bunnings sell balsa.
