Högert Technik Bi-metal Hole Saw 22 mm, M42 Steel

The Högert Technik 22 mm bi-metal hole saw is a professional-grade cutting tool engineered for high-performance drilling across a variety of materials. Constructed from premium M42 steel, this hole saw offers exceptional hardness and heat resistance, ensuring consistent results even during intensive use. Its advanced tooth geometry allows for smooth, clean cuts, reducing vibration and increasing overall drilling efficiency in demanding environments.

Advantages

The primary benefit of this bi-metal hole saw is its superior material composition, which combines the flexibility of a spring steel body with the extreme hardness of M42 high-speed steel teeth. This design significantly extends the tool's lifespan and prevents tooth breakage under stress. Furthermore, the optimized tooth configuration facilitates rapid chip removal, preventing clogging and ensuring a steady cutting speed throughout the operation.

Suitable for

• Drilling holes in structural steel and stainless steel
• Cutting through soft and hard wood
• Processing PVC and other plastics
• Professional construction and renovation projects

When it may not be suitable

This hole saw is not intended for drilling through hardened masonry, concrete, or ceramic tiles, as these materials will quickly dull the M42 steel teeth. It is also not recommended for use with high-impact hammer drills, as the lateral forces can damage the hole saw structure.

Key specifications

• Diameter: 22 mm
• Material: Bi-metal with M42 steel teeth
• Compatibility: Standard hole saw arbors
• Application: Metal, wood, plastic

How to use

To use the Högert Technik hole saw, securely mount it onto a compatible arbor and ensure it is tightly locked into your drill chuck. Mark the center point of the desired hole and use a pilot drill to stabilize the start of the cut. Apply steady, moderate pressure while maintaining a consistent drill speed, allowing the teeth to do the work without forcing the tool. Periodically retract the saw to clear debris from the cut.

What to consider before purchase

• Ensure your drill has the appropriate power and speed settings for the material being cut
• Verify that you have a compatible arbor for the 22 mm diameter
• Consider using cutting oil when drilling metal to improve performance and tool longevity

Usage recommendations

Always wear appropriate eye and ear protection during operation. Use a lower drill speed when cutting metal to prevent overheating the teeth and to maintain the integrity of the M42 steel.
