• Quantity: 1 piece
• Compatibility: designed for use with standard drill arbors and adapters
• Intended use: cutting circular holes in a range of common construction materials

How to use

Secure the hole saw to a compatible arbor following the arbor manufacturer’s instructions, then mount the assembly in a drill with appropriate speed and torque settings for the material. Mark the center of the intended hole and, where possible, use a pilot bit or center punch to prevent wandering. Start drilling at low speed to establish the cut, then increase speed as appropriate while applying steady axial pressure. Withdraw periodically to clear debris and avoid overheating. Finish the cut until the hole saw passes completely through the workpiece.

Usage recommendations

Use cutting speeds and feed rates suitable for the specific material to extend tool life. For harder or abrasive materials, reduce speed and apply light, steady pressure. Wear appropriate eye and hand protection and clamp the workpiece securely before drilling. Clean the saw teeth and remove debris after use to maintain cutting performance.
