## Summary description

The Yato YT-60373 diamond drill bit is designed for precise drilling. With a diameter of 4.2 cm, it is suitable for various materials, ensuring durability and efficiency in use. This drill bit is ideal for creating clean holes in hard surfaces.

## Long description

The Yato YT-60373 diamond drill bit with a diameter of 4.2 cm is designed for precise drilling in hard surfaces. Constructed with diamond-grit cutting edges bonded to a metal body, the bit provides steady cutting action and extended life when used with appropriate drilling techniques and coolant. Its size and build make it suitable for creating clean, round holes in ceramic tiles, stone, glass and similar rigid materials where accuracy and edge integrity are required.
Advantages
Diamond abrasive on the cutting edge ensures improved wear resistance compared with conventional bits, allowing for longer service life when drilling hard materials. The solid construction maintains concentricity for consistent hole shape and minimizes chipping around the hole perimeter. Designed for wet or cooled drilling, the bit dissipates heat effectively, which helps preserve the diamond bond and reduces the risk of overheating. Its 4.2 cm diameter provides a larger opening for installations that require substantial through-holes.
Suitable for
Drilling holes in ceramic and porcelain tiles
Creating openings in natural and engineered stone
Drilling glass panels and mirrors with controlled feed
Preparing larger-diameter holes for plumbing fixtures or electrical conduit through hard surfaces
Key specifications
Cutting material: diamond grit bonded to metal
Diameter: 4.2 cm
Intended use: drilling hard, brittle materials (tiles, stone, glass)
Cooling method: compatible with wet/cooling-assisted drilling
Typical mounting: compatible with standard drill chucks and suitable adapters
How to use
Select an appropriate drill motor and secure the workpiece before starting. Mark the centre point of the hole, start at low rotational speed and apply steady, even pressure to avoid skating or cracking. Provide continuous water flow or periodic coolant to the cutting interface to lower temperature and remove debris; avoid dry drilling on brittle surfaces. If a backing board is used for through-holes, support the material to reduce breakout when the bit exits the far side. After completing the hole, stop the drill and allow the bit to cool before handling or storing.
Usage recommendations
Use a drill with adjustable speed and a firm, steady hand; maintain coolant flow during operation and periodically inspect the bit for wear. Replace the bit when cutting performance declines or when diamond bond erosion becomes apparent to ensure consistent hole quality and safe operation.
