Review on Efficient Installation: KATA 19 152mm Mandrels for Plywood Projects by Charles Collier

I needed to drill some holes in the drywall for the top floor and found this kit, many sizes and all the accessories I need at a good price. I wasn't disappointed, it worked great. I was able to easily assemble and tighten the chuck, bit and saw. It was very durable and slid like clockwork over the drywall where I had no problems like I've ever had. I even cut a quarter inch piece of plywood and he went through it too. After I was done the blades still looked good, not a single stain on the steel and every tooth looked good too. I also like the compact body, everything fits perfectly and is small enough to easily store in my closet. There are no cons, the set suits me perfectly, I am very happy with the purchase.
