Promac Heavy Duty Core Drills are engineered to excel in the most challenging concrete and masonry applications, offering unparalleled durability and performance. Designed for professionals who demand reliability in tough conditions, these core drills are the ideal choice for heavy-duty tasks.
Key Features:
- Tapered Drive System: This innovative design allows for easy connections to adaptors, extensions, and pilots, providing flexibility to switch between machines, core diameters, and lengths to suit your specific needs.
- Scrolled Flute Design: The scrolled flutes efficiently remove trapped spoil, ensuring that the core drill consistently engages with fresh material. This feature not only speeds up the drilling process but also extends the tool’s lifespan by minimizing the need for frequent bit removal.
- 4mm Thick Heavy Duty Wall: Manufactured from solid steel stock, the 4mm thick wall strikes a perfect balance between strength and speed, providing the durability required for demanding drilling tasks without sacrificing performance.
- Chisel-Action Tungsten Carbide Teeth: Designed to rapidly cut through the toughest masonry materials, the chisel-action teeth feature a solid flat tooth angle that rips through masonry quickly, enabling fast and efficient drilling.
Ideal for use in:
- Heavy-duty concrete
- General concrete
- Hard bricks
- Soft bricks
- Lightweight blocks
- Natural stone
- Constructional granite
- Limestone
The Heavy Duty Core Drills are purpose-built to handle the most demanding projects with ease, ensuring that you can rely on them for consistent, high-performance drilling across a wide range of masonry materials. Whether you're tackling heavy-duty concrete or delicate natural stone, these core drills deliver the speed, durability, and precision you need to get the job done right.
Tech-Tip
- Pro-HD cores can be re-tipped as long as there is not too much damage to the core drill wall
Recommended Speed
- Recommended speed for these cores is largely governed by the power tool itself. This is because they are designed to be used in power tools where in the majority of cases there is no facility to regulate the speed (SDS Plus, SDS Max machines etc.).
- If used in a machine where speed regulation is possible, a general recommendation is the larger the diameter of the core drill being used, the slower the speed.
