## Long description

Prox core drill bit set with tungsten carbide teeth includes four diameters — 33 mm, 53 mm, 67 mm and 73 mm — designed for drilling precise circular openings in a range of construction materials. The set is intended for use with standard chuck drills and rotary drilling machines. Tungsten carbide teeth improve cutting performance and durability when working with concrete, brick, tile and other masonry materials while the standard shank ensures reliable fit and easy replacement.
Advantages
The tungsten carbide cutting edges provide increased wear resistance and maintain sharpness longer than carbon-steel alternatives. A selection of four popular diameters covers common installation and service tasks, reducing the need to change tools during work. Compatibility with standard drill chucks simplifies mounting and improves operator comfort during prolonged use.
Suitable for
Creating holes for pipes, conduits and cables in concrete and brick walls
Drilling openings for sanitary and plumbing fixtures through tiles and masonry
Preparing circular cutouts for HVAC and ventilation installations
General renovation and construction tasks requiring accurate round holes
Key specifications
Core bit diameters: 33 mm, 53 mm, 67 mm, 73 mm
Cutting material: tungsten carbide teeth for enhanced durability
Applicable materials: concrete, brick, tile and general masonry
Shank type: standard shank compatible with common drill chucks
Intended use: rotary drilling and core cutting in construction tasks
How to use
Select the core bit diameter appropriate for the required opening and securely mount the bit in the drill chuck. Position the bit perpendicular to the work surface and start at low speed to establish the cutting groove, then increase speed and apply steady pressure while allowing the tool to cut. For deeper holes periodically withdraw the bit to remove dust and debris and avoid overheating. Use proper coolant or water feed if the material and tool type allow, and ensure the workpiece is properly supported and clamped before drilling.
Usage recommendations
Wear appropriate personal protective equipment including safety glasses, gloves and a dust mask. Use a drill with sufficient power and torque for the chosen diameter, and avoid excessive side load on the core bit to prolong life and maintain cutting accuracy.
