Hole Saw 4932430327

Bimetal cobalt HOLE DOZER™ hole saws - sets

• The latest technology ensuring maximum performance.
• Tooth design – a design with a variable number of teeth 4-6 per inch with a positive tooth angle of 10° provides the following benefits: - Faster and more aggressive cutting. - Higher heat dissipation during cutting – teeth remain sharp longer. - Deeper, curved gullets between teeth provide more effective chip removal, preventing clogging and temperature rise. - Specially selected tooth angle shows less tendency to tear thinner materials. - Teeth are alternately set to the sides, minimising stickiness and friction. - Low feed pressure – achieved through the combination of aggressive tooth geometry and effective chip removal, resulting in less force required during drilling.
• Tooth material - the best Matrix II high-speed steel is used on the toothed section of the hole saw. Matrix II steel contains 8% cobalt, allowing the teeth to retain their initial hardness longer, even at high working temperatures during metal cutting. - Bimetal construction – high-speed steel teeth are laser welded to a high-alloy steel body. The teeth are then vacuum-hardened to 65 HRC at 600°C to provide maximum durability and utility. - Due to the high abrasion resistance of Matrix II steel, these saws are ideal for cutting difficult and hard materials such as stainless and acid-resistant steel, as well as softer materials like wood.
• Hole saw body - the hole saw body made of 1.27 mm thick steel is rigid – retains shape but also shows flexibility. - Effective cutting depth is 41 mm.
• Back plate design - back plates are made of thick steel, ensuring holes do not enlarge over time. Thick backs increase strength and rigidity, minimising vibrations. - 4 holes with guide pins facilitate arbor placement. - Perfectly crafted round back plate, particularly important in larger diameter hole saws.
• Angled slots help in removing and ejecting the core.
• Application - high-quality production techniques ensure high rotational precision, making these hole saws suitable for use in both hand and stand drills (manual feed only).
• This range of high-quality hole saws is an excellent solution for cutting all types of materials: - Steel up to a hardness of 1000 N/mm² - stainless and acid-resistant steel - non-ferrous metals - cast iron - aluminium - wood - medium density fibreboard (MDF) - plasterboard - laminated materials - PVC.
