Bosch Professional Multi Material Hole Saw - 44mm

This multi-material hole saw is designed to cut softwood, drywall, plastics, metal pipes, profiles, non-ferrous metals, and even stainless steel.

It is compatible with standard arbors and can be used with both rotary drills and impact drills/drivers.

Thanks to its HSS bi-metal construction with 8% cobalt, it lasts up to two times longer than a standard HSS M3 hole saw.

This 44mm hole saw offers a practical cutting depth of 44mm for various construction materials.

No, the hole saw requires a standard arbor, which is sold separately and not included with this product.

The hole saw features a new slot design specifically for easier plug removal. You can insert a screwdriver or punch into these slots to help dislodge the cut material.

While it can cut various metals including stainless steel, for extremely thick or highly hardened steel, specialized hole saws might be more appropriate. Always use correct cutting techniques and lubrication for metal.

The 8% cobalt content significantly enhances the hole saw's durability, heat resistance, and cutting performance, leading to a much longer tool life, especially in demanding applications.

Check if the teeth are dull or damaged; replace if necessary. For metal, ensure you're using a lower RPM and appropriate cutting fluid. Apply consistent, moderate pressure without forcing the cut.

Reduce drill speed, especially when cutting metal. For metals, use a cutting lubricant. Allow the tool to cool periodically. Ensure swarf is being cleared from the cutting area.

Utilize the new slot design by inserting a screwdriver or punch into the slots to pry out the plug. For persistent plugs, gently tap the hole saw on a sturdy surface.

Ensure the workpiece is firmly clamped and stable. Verify that the pilot drill bit is secure and guiding correctly. Maintain a steady hand and consistent pressure throughout the cut. Check for bent or damaged teeth.

Confirm that the hole saw is securely screwed onto the arbor and the arbor is tightly clamped in the drill chuck. Ensure the pilot bit is straight and not bent. Reduce drill speed.
