Milwaukee Quik-Lok™ Hole Enlargement Hole Saw Arbor

(Use only with 2 hole saws installed)

The Milwaukee 49-56-7576 QUIK-LOK™ Hole Enlargement Hole Saw Arbor Adapter is designed to increase the size of an existing hole using a hole saw system. Built for use with the Milwaukee QUIK-LOK™ Hole Saw Arbor System, this reusable adapter allows users to mount two hole saws simultaneously—one to guide the existing hole and the larger one to enlarge it. The pin adapter design helps prevent thread stripping and binding, especially when using large diameter hole saws or encountering high torque. Compatible with industry-standard threaded hole saws, this adapter works with hole sizes ranging from 9/16" up to 6-7/8", making it a practical solution for enlarging existing holes without starting from scratch—because sometimes the hole you drilled yesterday suddenly needs to be bigger today.
