Milwaukee 49224102 Hole Dozer Bi-Metal Hole Saw Set – 17 Piece
Product Description
The Milwaukee Hole Dozer 17-Piece Bi-Metal Hole Saw Set is engineered for superior cutting performance across a wide range of materials. Manufactured using Milwaukee’s Matrix II high-speed steel with 8% cobalt, the hole saw teeth retain exceptional hardness even under high heat, ensuring long-lasting durability in demanding metalworking applications. Its bi-metal construction, vacuum-hardened to 65 HRC, offers outstanding strength, wear resistance and operational life.
Designed for fast, efficient and clog-free drilling, the Hole Dozer range features optimised tooth geometry, deep curved gullets and reinforced back plates for maximum reliability. Whether you are cutting stainless steel, cast iron, MDF, PVC or wood, this premium kit delivers consistent precision and productivity on site or in the workshop.
Key Features
- High-performance Matrix II steel teeth: Made from premium high-speed steel containing 8% cobalt, ensuring excellent heat resistance and prolonged sharpness when cutting metals.
- Bi-metal construction: Laser-welded HSS teeth onto a high-alloy body, vacuum-hardened to 65 HRC for maximum strength and durability.
- Optimised tooth design: 3.5 TPI with a positive 10° tooth angle for aggressive cutting, improved heat dissipation, cleaner chip evacuation and reduced snagging on thin materials.
- Less feed pressure required: Efficient tooth geometry and chip clearance reduce the force needed during drilling.
- Rigid hole saw body: 1.27 mm thick steel provides strength and elasticity, with an effective cutting depth of 41 mm.
- Reinforced back plate: Thick steel back plates resist wear, minimise vibration and ensure accurate, round cutting over time.
- Four drive pin holes: Enable quick and secure arbor alignment, especially useful on larger diameters.
- Diagonal core-ejection slots: Allow faster removal of cut material for smoother workflow.
- Versatile applications: Suitable for both hand drills and pillar drills (manual feed), offering high rotational precision.
- Ideal for multiple materials: Compatible with steel (up to 1000 N/mm²), stainless steel, cast iron, aluminium, non-ferrous metals, MDF, timber, gypsum board, sandwich materials and PVC.
