Milwaukee 49224152 Hole Dozer Bi-Metal Hole Saw Set - 14 Piece
Milwaukee 49224152 Hole Dozer Bi-Metal Hole Saw Set – 14 Piece
Product Description
The Milwaukee Hole Dozer 14-Piece Bi-Metal Hole Saw Set is built for outstanding durability, accuracy and long-lasting performance across a wide range of demanding materials. Featuring Matrix II high-speed steel with 8% cobalt, the teeth maintain their hardness even under intense heat, making them ideal for cutting both tough metals—such as stainless and acid-resistant steels—and softer materials like wood and plasterboard.
Engineered with Milwaukee’s advanced bi-metal construction and vacuum-hardened to 65 HRC, these hole saws deliver exceptional wear resistance and extended lifespan. The optimised tooth geometry, reinforced back plates and deep curved gullets ensure smoother, faster and more efficient drilling, whether using a hand drill or pillar drill with manual feed.
Key Features
- Matrix II premium HSS teeth: 8% cobalt content provides superior hardness retention and exceptional performance when cutting metals.
- Robust bi-metal construction: Laser-welded HSS teeth and hardened alloy body deliver maximum strength and longevity.
- Optimised 3.5 TPI tooth design: Positive 10° angle ensures aggressive, fast cutting with improved heat control and reduced snagging.
- Deep curved gullets: Improve chip clearance, reduce clogging and help prevent heat build-up during drilling.
- Low feed pressure required: Efficient cutting geometry reduces operator fatigue and increases productivity.
- Strong 1.27 mm steel body: Rigid yet flexible design retains shape while providing an effective cutting depth of 41 mm.
- Reinforced back plates: Thick steel back plates improve rigidity, reduce vibration and prevent hole enlargement over time.
- Four drive pin holes: Allow precise and secure arbor alignment, especially useful for larger diameter saws.
- Diagonal ejection slots: Aid quick and easy removal of cut cores for improved workflow.
- Wide material compatibility: Suitable for steel (up to 1000 N/mm²), stainless steel, non-ferrous metals, cast iron, aluminium, wood, MDF, plasterboard, sandwich materials and PVC.
