The Milwaukee HOLE DOZER Bi-Metal Hole Saw Set (model 49224152) is a professional-grade 14-piece kit engineered for fast, clean cuts in wood, metal, plastic, PVC, drywall, and composites. Featuring patented Rip Guard Tooth Geometry and variable pitch design, these hole saws deliver up to 3X longer life and faster cutting compared to standard bi-metal hole saws. The set includes eight popular sizes from 3/4" to 2-1/2" (19mm to 64mm), two arbors (3/8" and 7/16" hex shank), a 1/4" cobalt pilot bit, and a 1-1/4" to 6" adapter. All components are stored in a durable carrying case for easy transport and organization.

Advantages

The variable tooth pitch minimizes vibration and noise, while the cobalt pilot bit ensures long-lasting precision. This set is ideal for electricians, plumbers, HVAC technicians, and general contractors who demand reliability and performance.
