Bi-Metal Hole Saws Operating Speed & Important:
For longer saw life and lower operating costs, the following recommendation need to be observed:
1. Use the correct arbor for the size saw to be used.
2. Use pin-type arbors for hole saws larger than Dia. 32. When mounting, Lift up the disc with the pins and then screw the arbor down into the hole saw as far as it will go. Fit the drive pins into the pin holes in the hole saw by turning the hole saw backwards. Push the pins in. Check that they are securely locked.
3. Check regularly to make sure the drive pins are in the right position.
4. Check that the arbor shank is securely inserted in the chuck on the drive unit. Tighten with chuck key.
5. Cutting oil should be used when sawing steel. Do not use cutting oil when sawing cast iron. The cutting pressure should, however, be high so that each tooth cuts deep. Paraffin can be used when sawing aluminium.
6. Use the correct rotation speed! Too high or too low a speed will decrease the life of the cutting edge.
7. If the hole saw vibrates during sawing, the teeth may became damaged and break. The result is often a rough, imperfect hole.
8. Apply the hole saw perpendicular to the workpiece. If the hole saw is titled, this will cause uneven loading and abnormal wear on both the saw teeth and the grilling machine. Moreover, the dimensional accuracy of the hole saw can be affected.
9. Clear away chips and slugs frequently in order to prevent overheating.
