The MEXCO Wet Core Drill (20mm) is designed for professional contractors and stone fabricators who require precise, high-performance drilling in natural stone and man-made materials. Its primary strength lies in its laser-welded durability, which maintains structural integrity during intensive use; however, users must note that this bit is specifically optimized for wet-cutting applications and should not be used dry to avoid premature wear.

No, this bit is specifically optimized for wet-cutting applications. Using it dry will cause it to overheat and fail prematurely.
It is designed for natural stone (such as granite and marble) and man-made materials like concrete or porcelain.
Maintain a steady water flow, use the correct rotation speed for the material, and avoid applying excessive side pressure.
This specific model is 20mm in diameter.
Yes, laser welding provides a much stronger bond between the segments and the core, significantly reducing the risk of segment detachment.
The segments may be glazed; dress the bit by drilling into an abrasive stone block to expose new diamonds.
Check that the core drill rig is securely anchored and the bit is correctly seated on the drive spindle.
Ensure that the water flow is sufficient and consistent throughout the entire drilling process to cool the segments.
To begin, securely thread the bit onto the spindle of your wet core drill machine, ensuring it is tightened appropriately. Always verify the water supply system is clear and that water flow reaches the cutting face immediately upon start-up. For maintenance, clean the drill barrel after each use to remove slurry buildup. Store the bit in a dry environment to prevent corrosion of the steel body. If you notice a reduction in cutting speed, it may indicate 'glazing'—you can restore performance by making a few controlled passes into an abrasive material like a sandstone block to expose new diamond edges.
