Review on KnKut KK9 3 8 6 8 6 Inch Steel by Maurice Stavros

I was trying to drill a hole in the back of my self propelled lawn mower to fit a coupler for my new cyclone rake using regular TiN coated bits. The back of the Husquvarna self-propelled mower is obviously made of durable material because I tried it on all day and ended up only drilling one hole! I decided to order this bit for the second hole. I put it in my hand drill, applied some wd-40 to cool it, and drilled the hole in under a minute! Great beat! I am very happy with it.
