Milwaukee Large Thread Quick-Change Hole Saw Arbor 7/16" Hex 49-56-9100E

MAXIMIZE STABILITY AND TORQUE TRANSFER IN LARGE-DIAMETER DRILLING

When driving hole saws 1-1/4 inches and larger, the mechanical stress on the arbor is significant, often leading to thread wear or excessive vibration that ruins the finish of the cut. This Milwaukee 7/16 in. Hex Shank Arbor is engineered to solve these stability issues through a dedicated drive plate system. By tightening the plate directly against the hole saw, you create a rigid, unified assembly that effectively eliminates the wobble common in standard threaded arbors. Constructed from a high-grade blend of hardened carbon and alloy steel, this arbor is designed to withstand the high-torque demands of heavy-duty drilling while maintaining its structural integrity over thousands of cycles. The 7/16 inch hex shank provides a secure, non-slip connection in any 1/2 inch chuck and is fully compatible with standard 7/16 inch extensions for deep-reach applications in framing or plumbing rough-ins.

• / Drive plate engagement mechanically locks the hole saw to eliminate vibration and ensure concentric rotation.
• / Hardened carbon and alloy steel construction provides the industrial-grade durability required for high-torque applications.
• / 7/16" hex shank prevents slippage within the drill chuck and integrates seamlessly with 7/16" extensions.
• / Tool-free quick-change operation allows for rapid saw swaps without the need for additional wrenches or tools.
• / Universal 5/8" x 18 thread compatibility fits all major brands of hole saws 1-1/4" and larger.
