Product details:

This added tooth strength combined with 8% cobalt, gives added life to the teeth, providing users with increased productivity on the jobsite, as well as consistent hole quality. This Milwaukee hole saw blade set includes Plug Jack, an all-access slot that provides access lower into the cup for thick material and higher towards the teeth for thin material for plug removal. Use Milwaukee's universal Quick-Change Arbors for fast, tool-free blade changes: 49-56-7240, 49-56-7250, and 49-56-9100. The QUAD EDGE tip delivers a precision start and four cutting edges to create smaller chips for faster removal and less heat leading to longer bit life. Milwaukee Red Helix Titanium Drill Bits provide up to 5X life versus black oxide drill bits.
