CRAFTSMAN BiMetal Hole Saw Kit, 7 Piece

[This review was collected as part of a promotion.] This review is for the CRAFTSMAN 7pc hole saw kit. So far, I have used this set to rough-in PVC five waste pipe plumbing systems and to install clothes dryer exhaust venting for several dryers, primarily cutting through fir wood framing lumber and through drywall, plywood flooring, plywood sheathing and cement board siding. The cutting performance of this product is remarkable. I consistently cut through 1-1/2 inch thick framing members with the 4-1/4 inch saw in under 40 seconds with no jams over signs of overheating. In fact the saw for each operation (with both larger and smaller hole saws) was no more than just warm when cutting through 2-inch dimension lumber and through cement board siding. These saws perform admirably in cement board siding, the cutting operation each time completed in less than a half minute for the largest of the saws in this set. The saws all have 1/2-inch wide, 1-7/8-inch deep relief slots that contribute to easy release of the cut core and effective chip release for cooling during cutting. The cutting depth for all of the saws is just short of 2-1/2 inches, about a half inch greater than other hole saws I own. These saws work so well that I am inclined to reach for them first when I must saw cut holes. This is a great product from my perspective because of its performance and durability

[This review was collected as part of a promotion.] Works very well. Seems very durable, fits my drill very well. Stays on with no problems. I like the variable sizes the kit came with. Very easy to use, easy to put on and take off. Easy to clean, none of the teeth broke off.
