Prox BI-metal Hole Saw 40mm HSS M2 Thread M14 HEX

The Prox BI-metal Hole Saw 40mm HSS M2 Thread M14 HEX is a reliable and durable cutting tool designed for clean and precise hole drilling across a wide range of materials. Manufactured from high-speed HSS tool steel combined with M2 high carbon steel, this bimetal hole saw provides enhanced wear resistance and longevity during demanding operations. With a diameter of 40 mm and a maximum drilling depth of 34 mm, it is well-suited for various professional and DIY applications, featuring a standard M14 thread and HEX mounting method for secure attachment to compatible equipment.

Advantages

This bimetal hole saw offers exceptional durability due to its robust HSS and M2 high carbon steel construction, ensuring stable performance and reduced wear even when working with tough materials. The precision-engineered tooth geometry allows for smooth cutting action, minimizing vibration and delivering clean edges. Its versatile design accommodates multiple material types, reducing the need for frequent tool changes during multi-material projects. Additionally, the standard M14 thread and HEX mounting provide reliable installation and quick setup.

Suitable for

• Drilling 40 mm holes in structural steel and stainless steel
• Creating openings in non-ferrous metals and aluminum
• Cutting through wooden boards and panels
• Piercing plastic materials and piping

When it may not be suitable

This hole saw is not recommended for drilling extremely hard masonry, concrete, stone, or ceramic tiles, as the bimetal construction is not designed for abrasive mineral surfaces. It is also unsuitable for applications requiring a drilling depth greater than 34 mm.

Key specifications

• Diameter: 40 mm
• Drilling depth: 34 mm
• Material: HSS tool steel and M2 high carbon steel
• Thread type: M14
• Mounting type: HEX

How to use

Ensure the hole saw is securely mounted to your power tool using the appropriate arbor and HEX connection with the M14 thread. Mark the center of the intended hole clearly on the work surface and use a pilot drill for accurate alignment. Start drilling at a moderate and controlled speed, applying steady, even pressure without forcing the tool. For metal cutting, the use of appropriate cutting fluid or oil is recommended to reduce heat buildup and extend the lifespan of the cutting edges. Periodically clear out debris from the saw interior during deep cuts.

What to consider before purchase

• Verify that a 40 mm diameter matches your specific project requirements
• Check that your power tool and arbor support M14 thread and HEX mounting
• Ensure the 34 mm maximum drilling depth is sufficient for your material thickness
• Confirm that the target material is among the supported types such as metal, wood, or plastic

Usage recommendations: Always wear appropriate personal protective equipment, including safety glasses and gloves, during operation. Maintain a moderate drilling speed and use cooling lubricants when cutting metals to maximize tool durability and prevent overheating.
