Guidelines for Successful Hole Saw Operation
- The pilot drill must extend beyond the edge of the hole saw teeth by 1/8″.
- Always secure the material to be cut. If not, the turning action of the hole saw will cause the workpiece to spin or slip.
- Start the hole saw square to the workpiece surface with steady feed pressure. Unbalanced tooth engagement will result in erratic hole saw action and could cause tooth strippage.
- Follow the recommended standard hole saw operating speeds.
- Hole saws should be worked in and out to help clear chips when working at the upper ranges of the hole saw’s capacity.
- Whenever possible, use a cutting oil (except with cast iron or wood) to help clear chips and lubricate the blade for longer life.
- Occasionally check the mandrel’s drive pins to prevent them from vibrating out of the hole saw’s drive pin holes.
- Always wear eye protection.
