Application: 1. When using the hole saw, add coolant constantly to dissipate heat and prolong life. 2. For 2mm iron panel holes, use a hand drill or bench drill; for more than 2mm, use a bench drill and drill about 1mm deep, then use a positioning drill to drill through along the saw seam for easier chip removal. 3. The cutting material must be fixed well and at a 90° right angle to the drill opening. 4. Do not over-tighten screws, and remove debris from teeth for cutting efficiency. 5. When the cutting material is 10mm or more, remove the spring on the positioning drill.
