1Pc Wet CNC Diamond Core Bits
1Pc Wet CNC Diamond Core Bit – Precision Drilling Tool for Stone, Marble, and Granite
The 1Pc Wet CNC Diamond Core Bit is a high-performance drilling tool designed for precision wet drilling applications on hard and brittle materials. Engineered for professional use, this diamond core bit delivers clean, accurate holes with minimal chipping, making it an essential accessory for stone fabrication, construction, and CNC machining operations. Ideal for granite, marble, natural stone, engineered stone, porcelain, and ceramic surfaces, this tool ensures efficiency, durability, and consistent results.
Designed for Wet CNC Drilling Applications
Specifically developed for wet use, this CNC diamond core bit requires water cooling during operation. Wet drilling significantly reduces heat buildup, extends tool life, and improves cutting performance. Continuous water flow helps remove debris, minimizes friction, and ensures smoother drilling with precise edges. This makes the core bit suitable for high-speed CNC machines as well as manual drilling setups that support water feed systems.
Premium Diamond Cutting Technology
The cutting edge is embedded with high-quality industrial diamonds, carefully bonded to provide superior cutting strength and long-lasting performance. These diamonds maintain sharpness even when drilling through extremely hard materials, ensuring fast penetration and consistent hole quality. The balanced diamond distribution reduces vibration and allows for smooth, controlled drilling.
High-Strength Steel Body for Stability
Manufactured with a reinforced steel core, the bit offers excellent structural stability and resistance to deformation. The rigid body design ensures accurate drilling, reduced runout, and improved control during operation. This results in cleaner holes, improved precision, and reduced risk of cracking or damaging the material being drilled.
Clean, Accurate, and Chip-Free Results
The Wet CNC Diamond Core Bit is designed to produce smooth, clean holes with minimal edge chipping. This is especially important for visible surfaces such as countertops, tiles, and decorative stone elements. Whether drilling mounting holes, sink cut-outs, or fixture openings, this core bit delivers professional-grade results every time.
Wide Range of Applications
This diamond core bit is suitable for:
Granite and marble drilling
