Diamond Wet Core Drill Bit - Product Description
Product Overview
Diamond wet core drill bits are professional drilling tools designed for fast, smooth, and precise hole drilling in hard materials such as reinforced concrete, granite, marble, brick, and masonry. With high-quality diamond segments and optimized bonding technology, these bits ensure excellent cutting performance and long service life.
Wet drilling technology uses water cooling to reduce heat, improve efficiency, and extend the lifespan of the drill bit.


Key Features
- High Diamond Concentration
Premium industrial-grade diamonds ensure fast drilling speed and superior cutting efficiency.
- Water Cooling System
Requires water during operation to reduce temperature, minimize dust, and extend tool life.
- Laser Welded Segments (Optional)
Strong bonding technology enhances durability and prevents segment loss during heavy-duty work.
- Smooth & Accurate Drilling
Produces clean holes without cracking or chipping the material surface.
- Long Service Life
Optimized segment height and bond matrix provide extended drilling performance.
