Maximize Productivity with the Deep-Cutting Diablo 1-11/16 Inch Bi-Metal Hole Saw

Upgrade your drilling capabilities with the Diablo DHS1688 1-11/16 in. Bi-Metal Hole Saw, a high-performance accessory designed to deliver faster cuts and superior longevity. Unlike standard hole saws that struggle with depth, this tool features an impressive 2-3/8 inch cutting depth, allowing you to bore deeper holes in a single pass—perfect for double studs or layered materials. The saw is constructed with a premium bi-metal blend and features a variable tooth design that reduces vibration, ensuring a smooth finish in wood, metal, plastic, and aluminum.

Efficiency is at the heart of the Diablo system. This hole saw is optimized for use with the Snap-Lock Plus™ mandrel system (sold separately), which revolutionizes how you work by enabling quick, tool-free cup changes and rapid plug ejection. Instead of wrestling with a screwdriver to pry out stuck material, the Snap-Lock design allows you to eject plugs instantly, keeping downtime to a minimum. Whether you are a professional tradesperson or a serious DIY enthusiast, this hole saw provides the durability and speed required for demanding projects.

Note: Snap-Lock Plus™ Mandrel is sold separately.
