Suitable for cutting circular holes in materials such as wood, PVC panels, plastic, thin metal sheets, and thin metal pipes. How to assemble the hole saw kit? 1. Insert the drill bit into the spindle and tighten the screws on both sides of the spindle with a hex wrench. 2. Insert the main shaft from the bottom of the blade to the top. 3. Place the mounting plate on the saw blade, then tighten the nut to secure the mounting plate and prevent damage (the mounting plate should be positioned between the saw blade and the nut). The washer must not be installed in reverse. 4. Ensure that the screws on the sides of the chuck are tightened with a hex wrench and there is no play to ensure cutting accuracy. 5. Drill bits and hole saws are prone to getting stuck and cannot be removed during use, which may cause the drill bit to break. Reduce the drilling speed during operation. Recommended drilling speed: RPM ≤ 1000 for machines to extend the service life of the hole saw. 6. When using the hole saw kit, wear safety goggles, a mask, and gloves.
