Handy little tool will cut holes from 40mm to 120mm in fiberglass and aluminium so great for those clocks or any hole really . Easy to use. What can I say it cuts holes and does what it's meant to do.

Great tool for easily cutting circles out of sheet materials. I cut through 3mm alloy plate relativly easily with good results. Dont attempt this without a pillar drill, unless you have arms like the Hulk.
