Precision Engineered Design: Our core drill is designed with universal 5/8"-11 thread, making it easy to quickly mount to standard core drilling equipment or handheld drills, providing versatility and convenience.
Dual-use wet and dry: Our diamond core drill bit is suitable for both dry and wet cutting conditions. Dry cutting provides higher speeds, while wet cutting reduces dust, meeting different project needs. It is easy to use with high flexibility.
Wide Applications: Our wet/dry drill bit is ideal for drilling in hard concrete, brick, stone and other tough materials. It is widely used in air conditioning installations, pipelines, stair railings, highways, airports and various construction scenarios.
Perfect Kit: Our concrete core drill comes with a pilot bit for precise alignment, preventing the drill bit from deviating from the target location. An additional 3.15 inch / 80 mm diamond saw blade is included for cutting tasks, eliminating the need for separate purchases.
