Used this set to run a new bathroom in a 105yr old house. The wood in this house was extremely hard, but that didn't stop these bits. Cut nice holes very quickly even with the largest bit. Would highly recommend this set!

2.) big improvement over bi-metal hole saws

With wood, particle board, MDF, Hardie siding, and plywood, these hole cutters will blow through the boards in seconds. Big difference in performance with cordless drills where even 18 volt drills can make 6" holes in thick boards using these hole cutters. Basic difference is a design that has a few large tungsten carbide teeth and large side slots instead of a continuous piece of metal with tiny high speed steel teeth.

The shavings are cleared as the hole is cut and there is no contact between the sides of the hole cutter and what is being cut. This makes better use of the drill's power as it all goes into cutting and there is no burning of the board, even with MDF and chipboard.

The carry case is very strong and definitely designed to hold up for many years of use. I like that it will hold a 4-5/8" hole size which is unusual but a size I use all the time.

There are 3 different kinds of pilot bits included so I have one for masonry and one for wood and a general use twist drill too. The wood bit is a good choice for general boring in wood. It cuts faster and as it tapers down at the bottom the cut piece of wood just falls away from the hole cutter as soon as it cuts through the board. No need to take apart the hole cutter and then knock out the plug with a screwdriver and a hammer which is the case with bi-metal hole saws.

These are not something you would use on metal or concrete but for other materials these are incredibly fast and the cost is actually less than that of bi-metal when you figure in how long they last. I can cut faster with these Blue Boar hole cutters and a 18 volt cordless drill in lumber than I can using a heavy corded stud drill with selfeed drill bits. These are not going to handle nail strikes but then neither will selfeed drill bits which cost a lot more and are a lot slower at making holes.
