A: It is mainly suitable for super-hard materials such as glass, ceramics, stone, cemented carbide, artificial quartz stone, and sintered metal. It is not recommended for drilling soft materials like wood or plastic, as this may cause coating wear and reduce service life.

A: Yes. The drill bit adopts an integral cemented carbide base with good rigidity, and the diamond coating ensures uniform cutting. The drilling error can be controlled within 0.01-0.03mm, which is suitable for high-precision scenarios such as electronic equipment glass substrate drilling and mechanical part processing.

A: Wear protective goggles to prevent debris from splashing into the eyes; use gloves to avoid slipping when holding the equipment; do not touch the drill tip immediately after drilling, as it may be hot; ensure the workplace is well-ventilated when using coolant.
