Review on Efficient Installation: KATA 19 152mm Mandrels for Plywood Projects by Alexander Chavis

I love a product that does what it promises but this product doesn't deliver what it says. It says he can drill holes in wood, but not of different sizes. I have a drill bit up to 2" that uses my drill press to drill holes in wood. This will not drill holes in 5 inch diameter wood. Maybe it's my cordless drill? "Wood paneling on my porch for a lamp. I ended up giving up three quarters and using my set of chisels to figure out the rest. Imagine you have 8 different sized drill bits, a fully loaded Dewalt and a goddamn chisel.
