Key specifications

How to use

Fit the appropriate hole saw blade onto the heavy zinc alloy arbor and secure according to the arbor’s fastening method. Mount the arbor in a suitable drill and set the drill to an appropriate speed for the material being cut. Apply steady pressure and keep the drill perpendicular to the work surface. For plastics and acrylic, use lower speed and avoid overheating; for hardwoods and metals, use progressive cutting with controlled feed to avoid blade binding. Remove debris periodically and allow the blade to cool if it becomes hot.

Recommendations

Use appropriate personal protective equipment (eye protection and gloves), clamp workpieces securely, and select correct drill speed for the material. Avoid excessive lateral force and let the hole saw do the cutting to prolong blade life.
