Review on 🔧 Enhanced Performance: Bi Metal 8 Inch Klein Tools 31958 – Perfect for Professional Use! by Bob Fasho

Needed to install an exhaust fan that requires a 6" hole. I chose the Klein Tools brand because I've always had good luck with their products. I used my Milwaukee Arbor and it fit perfectly. I had to drill through the aluminum paneling in the attic. I had to run this backwards to get through the siding first. The teeth were too sharp and aggressive, and when they grabbed the drill, it nearly fell out of my hand. So I basically started my pilot hole and then flipped the drill bit until it went through the aluminum siding and then reversed the direction of the drill bit and it blasted the wood with ease. No problem and hopefully I can use this in the future. Projects like installing regular lighting :)
