🔧A hole saw is used in foundation drilling when augers cannot break through hard layers of rock.
⚙️The hole saw is used as a tool to break through the hard layer and create an opening for further drilling.
🩹The teeth of the hole saw can sometimes break due to the force used during drilling, requiring replacements.
🔗The hole saw is welded onto the rock drill using a perimeter weld for stability and durability.
🧑🏭The welding process requires skill and precision to ensure a secure attachment of the hole saw.
