Hole saw for metal MODECO MN-61-417 bi-metal 44 mm

Bi-metal hole saw MODECO MN-61-417 with a 44 mm cutting diameter is designed for making precise circular cutouts in metal sheets, pipes and profiles. Made from bi-metal construction, this hole saw combines a high-speed steel cutting edge with a flexible carbon steel body to increase durability and resistance to heat during drilling. It is compatible with standard drill chucks and drill presses, making it suitable for professional metalworking and workshop use where reliable performance and clean holes are required.

Advantages

The bi-metal design provides a long tool life and improved resistance to wear and heat compared with single-material cutting wheels. The tooth geometry is optimized to cut through various ferrous and non-ferrous metals while minimizing burrs and deformation around the hole. The saw's 44 mm diameter offers a common size for electrical, HVAC and mechanical installations, enabling accurate fit for conduits, pipe penetrations and mounting holes. The rigid yet slightly flexible body reduces the risk of cracking under load and allows stable performance in both hand drills and drill presses.

Suitable for

• Cutting circular holes in metal sheets and plates
• Creating openings for conduits and cable glands in electrical installations
• Making service and access holes in HVAC ducts and metal enclosures
• General metal fabrication and workshop tasks requiring 44 mm cutouts

Key specifications

• Cutting diameter: 44 mm
• Material: bi-metal (high-speed steel teeth + flexible steel body)
• Compatibility: standard drill chucks and drill presses
• Application: suitable for ferrous and non-ferrous metals
• Design: toothed cutting edge for clean circular holes with reduced burrs

How to use

Secure the hole saw in the drill chuck or arbor according to the drill manufacturer's instructions. Mark the centre of the required hole and, if available, use a centre punch to prevent wandering. Start drilling at low speed to establish the pilot position, then increase speed appropriate to the metal type while applying steady, moderate pressure. Use cutting lubricant when drilling harder metals to reduce heat and prolong tool life. After completing the cut, remove the workpiece and clear chips from the saw teeth before subsequent use.

Usage recommendations

Use suitable personal protective equipment including safety glasses and gloves, and secure the workpiece to avoid movement. For cleanest results on thin sheets, support the material close to the cut to reduce deformation. Replace or sharpen the saw when cutting performance declines to maintain hole quality.
