Högert Technik Bi-metal Hole Saw 38 mm M42 Steel

The Högert Technik bi-metal hole saw with a 38 mm diameter is a professional-grade cutting tool engineered for precision and durability. Constructed from high-quality M42 steel alloyed with cobalt, this hole saw provides exceptional heat resistance and structural integrity, making it suitable for demanding industrial and construction environments. Its robust design ensures consistent performance and a clean finish across a wide range of materials.

Advantages

The primary advantage of this bi-metal hole saw lies in its advanced material composition. The inclusion of cobalt in the M42 steel significantly enhances the tool's hardness and resistance to wear, allowing it to maintain a sharp cutting edge even under high-temperature conditions. The bi-metal construction combines a flexible backing material with a high-speed steel cutting edge, which effectively reduces the risk of tooth breakage and ensures a longer operational lifespan compared to standard carbon steel alternatives.

Suitable for

• Drilling holes in stainless steel and carbon steel
• Processing non-ferrous metals such as aluminum and copper
• Cutting through various types of wood and wood-based materials
• Working with plastics and PVC piping

When it may not be suitable

This hole saw is not intended for drilling into hardened masonry, concrete, or stone, as these materials will cause rapid dulling of the teeth. It is also not recommended for use on extremely thick metal plates that exceed the depth capacity of the saw.

Key specifications

• Diameter: 38 mm
• Material: M42 high-speed steel with cobalt
• Construction: Bi-metal
• Compatibility: Standard hole saw arbors

How to use

To achieve the best results, securely mount the hole saw onto a compatible arbor and ensure it is firmly locked into the drill chuck. Start the drilling process at a low speed, applying steady and even pressure to allow the teeth to engage with the material. It is recommended to use a suitable cutting oil or lubricant when drilling into metals to reduce friction and heat buildup, which helps preserve the sharpness of the tool. Periodically retract the drill to clear away accumulated debris or shavings from the cut.

What to consider before purchase

• Ensure the 38 mm diameter meets your specific project requirements
• Verify that your drill or drill press has sufficient torque for the material being cut
• Confirm you have the correct arbor size for this hole saw

Usage recommendations

Always wear appropriate personal protective equipment, including safety glasses and gloves, when operating power tools. Ensure the workpiece is securely clamped to prevent movement during the drilling process.
