For small-diameter drilling, the diamond drill bit with low vibration and low noise has made its debut.

• Supplied water cools the diamond-tipped teeth, removes dust, and increases drilling efficiency.
• Since the cutter and body are connected with a thread, simply replacing the cutter will suffice when the cutter teeth are worn.
• Cracks do not get clogged with dust. The backside surface breakaway is minimized after drilling.
• Drilling work with low noise and the least amount of vibration and impact transferred to the worker.

• Earthquake-resistant reinforcement work, water-proofing work, building exterior repair work, and drilling pilot holes for installation of anchor bolts.
• Concrete, mortar, stone, and ceramic tiles drilling work.
