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).
It took me 15 minutes to remove just a 1/2 inch piece of cedar fence after cutting. I have several Milwaukee hole saws where the cut material comes out immediately. Cutting the hole is only half the job - I wouldn't buy it again and while it's still practically new I'll be replacing it as I don't have all day to get the material out after cutting.
Pros
Works with standard or quick-change mandrels (requires quick-change adapter)
