Milwaukee hole saw set, Hole Dozer, 7 pieces, diameter 19 to 32 mm.

Cutting edge technology for unparalleled tool life. Tooth geometry features variable 4 to 6 TPI Vario toothing with a positive 10° tooth angle, resulting in faster and more aggressive cuts, lower heat generation for longer tooth life, greater tooth depths for better material removal, specially shaped teeth to reduce jamming in thin materials, reduced friction from set tooth pitch, and less contact pressure required due to aggressive tooth design and effective material removal.
