Τρυπάνι διαμαντιού Cimco 208770

The Cimco 208770 diamond drill bit is a single-piece, industrial-grade tool engineered for precision drilling with a diameter of 6.8 cm. It is designed to cut clean, accurate holes in a range of hard and abrasive materials while maintaining consistent performance over prolonged use. The bit's diamond cutting surface and robust core deliver stable operation and reduced chipping, making it suitable for detailed work that requires reliable hole quality and repeatability.

Advantages

The diamond coating provides high abrasion resistance and extended service life compared with conventional carbide bits. Its single-piece construction enhances strength and reduces the risk of separation or wobble during rotation. The large 6.8 cm diameter allows for efficient material removal and precise circular cuts, and the bit's design supports consistent cooling and debris evacuation to minimize thermal damage and clogging.

How to use

Secure the workpiece and mark the drilling point. Use a drill or core-drilling rig compatible with large-diameter diamond bits and ensure a stable, perpendicular approach. Begin at low speed to establish the cut, then increase to an appropriate moderate speed while applying steady, even pressure. Continuous or intermittent water cooling is recommended to keep the diamond surface cool and to flush out slurry. Avoid excessive force or high speeds that can cause glazing or premature wear of the diamond surface.

Recommendations

For best results, perform wet drilling with a consistent water supply, allow the bit to do the cutting without applying excessive pressure, and periodically check bit condition. When drilling glass or very thin tiles, consider backing the workpiece with a sacrificial support to reduce cracking. Use appropriate personal protective equipment, including eye protection and dust control when dry cutting is unavoidable.
