MILWAUKEE HOLE DOZER™ BI-METAL HOLESAWS
Provides cutting edge technology for maximum productivity. Suitable for cutting a range of different materials such as steel up to 1000 N/mm² strength - Stainless steel and acid resistant steel - Non-ferrous metals - Cast iron - Aluminium - Wood - Medium density fibreboard (MDF) - Gypsum plasterboard - Sandwich materials - PVC.
Features:
-TOOTH DESIGN: The variable 4-6 teeth per inch tooth design with a positive 10° tooth angle provides the following benefits:
- Faster and more aggressive cut.
- Improved heat dispersion during cutting ensures that the teeth stay sharper for longer.
- Deeper curved gullets provide more efficient chip clearance preventing clogging and heat build up.
- The special shaped tooth angle has less tendency to snag on thinner materials.
- Teeth are alternate/side set which minimises binding and friction.
- Requires less feed pressure which is achieved by the combination of aggressive tooth geometry and good chip clearance. This results in the need for less force during drilling.
TOOTH MATERIAL:
-The toothed area is designed with Type Matrix II premium high speed steel. The Matrix II steel contains 8% cobalt which allows the teeth to retain the original tooth hardness even at high working temperatures when used in metal cutting applications.
-Bi-metal construction.
-The High speed steel teeth are laser welded onto a high alloy steel body. They are then vacuum hardened to 65 HRC at a temperature of 600°C which gives maximum durability and life time.
-The high wear resistance of the Matrix II material makes these holesaws ideal for cutting difficult and hard materials such as stainless steel and acid resistant steels as well as softer materials like wood.
-Holesaw body designed from 1.27 mm thick steel which ensures its is rigid to retain its shape but also has built in elasticity.
-Effective sawing depth is 41 mm.
-Back plate design - The back plates are constructed with thick steel thus the holes will not enlarge over time. The thick backs add strength and rigidity which minimises vibrations. The 4 drive pin holes allow for easier arbor location. The perfectly manufactured round back plate is especially important for the larger diameter holesaws.
-The Diagonal slots aid the removal and ejection of the core.
-The High quality manufacturing techniques ensure high rotational precision making these holesaws are suitable for use both in hand and pillar drills (manual feed only).
