Review on ASNOMY 16 30mm Tungsten Titanium Plated Stainless: Durable and Stylish Metal for Various Applications by Brian Kingsford

I have a set of Makita and Dewalt hole saws that I use for wood, but they're almost useless on metal unless it's soft and thin. These chainsaws work on almost anything. I've drilled 1/4" aluminum with no problems and they work well in both my hand drill and drill press. Really appreciate the fact that extra pilot drill bits are included in the kit. Expensive but great.
