Description of π³ Bosch HB350 3 in 1 Bi-Metal Hole Saw
Progressor tooth design cuts faster and lasts longer in wood and metal applications. Reinforced shoulder for added strength and longer life. 8 percent cobalt alloy for longer life and higher heat resistance. Works with standard or Quick Change mandrels (Quick Change requires adapters).
Bosch quality control seems to slip - the saw I received was 1/16" too small. Other Bosch hole saws I've bought have been sized accurately, this was a one time issue and these saws cut and hold their edge fairly well.
Pros
Works with standard or quick change arbors (requires adapters for quick change)
I have a lot of Bosch tools and bought this hole saw to use with my Bosch hole saw set (Bosch HB25M Bi-Metal 25 Hole Hole Saw Set) I recently bought from Revain. I've only used this hole saw once to cut 1/2 inch thick plywood and it worked great.
Pros
Progressor tooth design cuts faster and lasts longer in wood and metal
