Review on MaxTool Carbide Concrete Composite CT00Y57R132A by Scoony Taker

Cuts through exterior plaster, hacksaw and wood substrate. The great thing is that this bit can be used on almost any material, so I don't have to buy multiple bits to install it in my home for electrical wiring. I removed the star because the bit wobbles a bit on the shaft, but that doesn't bother me when I'm working, it just loses some of its accuracy.
