Bosch Professional Multi Material Hole Saw - 29mm

This hole saw is designed for cutting a variety of common construction and interior materials, including wood, drywall, GFK (Glass Fibre Reinforced Plastic), and various metals like steel cladding.

The 8% cobalt content significantly enhances the hole saw's durability and wear resistance. This allows it to last up to 2x longer than standard HSS M3 hole saws, providing extended service life and consistent performance.

The Power Change plus system allows for quick and tool-free changes of hole saws and pilot bits. It also facilitates easier and faster removal of material plugs, saving you valuable time on the job.

The 29mm Bosch Professional Multi Material Hole Saw has a working length, or maximum cutting depth, of 44 mm.

No, this Multi Material hole saw is specifically designed for wood, drywall, GFK, and metals. For concrete or masonry, you would need to use a specialized masonry or diamond core bit.

It is recommended to use a powerful drill that has variable speed settings and a robust chuck. Ensure the drill can securely hold the Power Change plus arbor and provide adequate power for the material you are cutting.

To get the longest life from your hole saw, use the appropriate speed for the material, apply steady and even pressure, avoid overheating by taking breaks if needed (especially in metals), and keep the teeth clean. Also, use cutting lubricant when working with metals.

Ensure you are using the correct drill speed for the material; too slow can cause binding, too fast can overheat. Apply steady, consistent pressure, avoiding excessive force. Check if the hole saw teeth are dull or damaged and replace if necessary. Make sure the workpiece is securely clamped to prevent movement.

The Bosch Power Change plus system is designed for easy plug removal. Twist the hole saw off the arbor, and the pilot bit's collar typically helps eject the plug. If it's still stuck, gently tap the saw on a sturdy surface or use pliers to pull the plug out from the back, being careful not to damage the teeth.

This can occur if the drill speed is too high or if too much pressure is applied, particularly in softer materials like wood or drywall. Try reducing the drill speed and applying less pressure for a cleaner exit cut. Ensure the pilot bit is firmly guided throughout the cut. For wood, consider backing with a sacrificial piece of material to prevent blowout.
