Milwaukee Large Thread Pull-Back Arbor, 7/16″ Shank

MAXIMIZE UPTIME WITH RAPID-ENGAGEMENT MANDREL TECHNOLOGY

In high-production environments where switching between abrasive-cutting hole saws and standard bi-metal cups is constant, the 49-56-7240 Large Quick-Change Mandrel is an essential mechanical link. Engineered to eliminate the frustration of seized arbors and the need for secondary tools, this mandrel utilizes a pull-back collar design that allows for instantaneous cup swaps. Built from hardened steel to withstand the high-torque demands of 1/2″ drill/drivers, it ensures a positive lock that maintains concentricity even when boring through demanding materials like cement board, brick, or thick fiberglass.

• / Pull-back collar design enables tool-free hole saw changes for maximum jobsite efficiency.
• / 7/16″ Hex shank provides a non-slip grip in all 1/2″ and larger drill chucks.
• / Universal 5/8″ x 18 threading fits all hole saws 1-1/4″ and larger, including carbide grit and bi-metal options.
• / Hardened steel construction ensures long-term durability and resistance to thread stripping under heavy load.
