Concrete Turbo Core Drill Bits, ranging from 25mm to 450mm in diameter, are specialized cutting tools used for drilling holes in various hard materials, including reinforced concrete, stone, brick, wall, and hard rock. These core drill bits are designed for use with core drilling machines and are commonly used in construction, masonry, and other drilling applications. Here are some key features and information about these core drill bits:

Diameter Range: These core drill bits are available in a wide range of diameters, starting from 25mm and going up to 450mm. The choice of diameter depends on the specific hole size required for your project.

Concrete and Hard Material Drilling: These turbo core drill bits are specifically designed for drilling into hard materials like reinforced concrete, stone, brick, walls, and hard rock. They are equipped with diamond segments that provide effective and precise cutting.

Turbo Design: The "turbo" design features segments with a pattern that enhances the cutting efficiency and reduces heat generation during the drilling process. This design helps prolong the life of the core drill bit and ensures a smooth and clean hole.

Core Drilling Machines: These drill bits are typically used with core drilling machines. These machines are equipped with a motor and water supply system for cooling and lubrication during drilling. The water flow helps to remove debris and keep the bit cool.

Application: Core drill bits are commonly used in construction to create holes for various purposes, such as plumbing, electrical conduit, anchor bolts, and ventilation. They are also used in geological and mining applications for extracting core samples from rock.

Quality and Durability: High-quality core drill bits are essential for reliable and efficient drilling. Look for durable bits with high-quality diamond segments to ensure a long lifespan and consistent performance.

Safety and Water Supply: When using concrete turbo core drill bits, follow safety guidelines, wear appropriate personal protective equipment, and ensure a continuous water supply to the bit to prevent overheating and dust control.

Selecting the right core drill bit diameter and ensuring proper water supply and drilling techniques are essential for achieving clean and precise holes in hard materials. It's recommended to consult us for specific recommendations regarding the compatibility of the core drill bits with your core drilling machine and for guidance on choosing the right bit for your drilling project.
