Operation Cautions
1. The TCT hole saw kit is not suitable for concrete, sufficient water or lubricant will keep it cool while drilling.
2. When the hole is drilled through, please be careful not to hit the edge of the carbide hole cutter, because excessive impact will cause the cutting edge of the hole saw to be chipped and affect the drilling effect.
3. Remember to add coolant during continuous high-speed drilling.
4. After long-term use, the steel hole saw is in a hot state, and care should be taken to avoid scalding the skin when replacing it.
