RAPID-RELEASE EFFICIENCY FOR HIGH-VOLUME DRILLING OPERATIONS

The Milwaukee 49-56-7555 QUIK-LOK Arbor is engineered to eliminate the primary bottleneck in hole saw applications: the transition time between sizes and the frustration of seized threads. By utilizing a tool-free interface, this arbor allows for 3-6X faster changes compared to standard arbors, directly impacting jobsite throughput and professional ROI. The inclusion of a reusable pin adapter is a critical mechanical advantage, distributing torque away from the threads to prevent the common issue of stripping and binding under high-load drilling. Furthermore, its hole enlargement capability provides a versatile solution for correcting undersized penetrations from 1-1/4" to 6-7/8" without the need for complex custom jigs.

• / Universal compatibility with all threaded hole saws ensures seamless integration into existing accessory inventories.
• / Integrated QUIK-LOK mechanism enables tool-free saw changes, reducing downtime by up to 600% during multi-size rough-ins.
• / Reusable pin adapter design mitigates thread binding and stripping, extending the service life of both the arbor and the hole saw.
• / Specialized geometry supports hole enlargement from 1-1/4" to 6-7/8", providing a professional solution for field adjustments.
• / High-torque 7/16" hex shank provides a secure, non-slip grip in 1/2" drill chucks for maximum power transfer.
