Todd of Project Farm did his usual admirably-thorough testing on a number of hole saw brands, from DeWalt, Irwin, Bosch, Milwaukee, Lenox, Morse, and others, testing 13 brands in all. He tested for material hardness, speed of cut, accuracy of cut, chip dispersal, and wear on the bit. Three different thickness/hardnesses of metal were tested.
In the end, the best performer was the MK Morse brand with carbide teeth. Proving that expensive doesn’t always mean best, the MK Morse only costs $8.45 (compared to other brands costing upwards of $40). Todd also found that the Milwaukee Dozer ($9.45) performed very well, as did the Irwin (at $8.42).
