Task to drill 400 holes in 5mm Foamex sheet (pvc faced foam core) .. wheet is 2m x 1.6m so needs to be handheld tool.
About 100 of them are 0.03" (~0.75mm) and another 100 are 0.04" (~1.0mm)
My DeWalt cordless is a bit heavy to use for this task, and will not close down on 1.0mm or lower.
I thought to use a pin chuck .... tried 2 from Amazon, but they simply don't spin true (they were 1/4" hex fitting) ... think it needs to be a collet not a jawed chuck.
... any suggestions on a good pin chuck.
The alternative would be to buy a Dremel equivalent - again any suggestions one review praised this model above Dremel
