ELIMINATE BIT WALK AND MAXIMIZE DIAMOND DRILLING EFFICIENCY

The Milwaukee 49-56-7235 Pull-Back Arbor represents a significant mechanical upgrade for professionals frequently core-drilling through porcelain, stone, and dense tile. By integrating a retractable starter bit, this arbor eliminates the need for a traditional pilot hole, which often risks material fracturing or bit wandering on glazed surfaces. The pull-back pin design is engineered to solve the common industry pain point of thread binding and stripping, ensuring that high-torque applications don't lock the hole saw onto the arbor. When paired with Diamond Max™ hole saws, this system provides a high-ROI solution for installers demanding precision centering and rapid accessory transitions in the toughest masonry materials.

• / Retractable starter bit creates a precise divot in hard materials to prevent bit walk without requiring a separate pilot hole.
• / Pull-back pin engagement prevents the hole saw from binding or stripping threads under high-torque drilling.
• / Carbide-tipped starter bit ensures long-term durability and consistent performance in porcelain and natural stone.
• / Universal compatibility with all Diamond Max™ Hole Saws ranging from 1-1/4” to 4-1/2”.
