1. Please check the integrity of the hole drill before use.2. When the hole drill is installed in the electric drill, the three sides of the corresponding handle should be clamped.3. When drilling holes, keep the verticality of the hole drill and the workpiece.4. Use a small feed force when starting drilling, and use a medium feed force after positioning.5. During drilling operation, the speed should not be too low to avoid jamming of the knife edge and causing broken knife.6. When the center drill drills through the workpiece, the force should not be too large to avoid severe impact between the blade and the workpiece.7. After the hole drill drills through the workpiece, the workpiece should be withdrawn while the hole drill is rotating.Package Include:1 x 60mm hole saw1x high-speed steel drill bit1 x spring1 x L hex wrench
