Milwaukee 3-1/2″ HOLE DOZER™ Bi-Metal Hole Saw

MAXIMUM DURABILITY FOR HIGH-TORQUE METAL AND WOOD BORING

The Milwaukee 49-56-0193 3-1/2″ HOLE DOZER™ represents a significant advancement in bi-metal cutting geometry, specifically engineered to handle the high-torque demands of modern cordless drill/drivers. By utilizing a 3.5 TPI (teeth per inch) design, this hole saw balances aggressive material removal with mechanical longevity, particularly when boring through thick metals and nail-embedded wood. The integration of a specialized Thermoset Coating is a critical mechanical feature; it actively minimizes friction and heat buildup, which not only accelerates the cut but also preserves motor life and extends battery runtime by reducing the amperage draw during heavy-duty applications.

• / 3.5 TPI Tooth Geometry provides the ideal balance of speed and durability in the most demanding metal-cutting environments.
• / Plug Jack™ All-Access Slots utilize a staggered design to provide multiple points of leverage for faster slug removal and reduced downtime.
• / Thermoset Coating reduces drag and surface friction, delivering up to 25% more holes per charge on M18™ and M12™ platforms.
• / RIP GUARD™ Limited Lifetime Tooth Break Warranty ensures professional-grade ROI by protecting against the most common failure point in bi-metal saws.
