The Carat Reinforced Concrete Micro-Percussion Diamond Crown (Ø 82 x 315mm) is a dry universal core drill bit designed to bore through all types of concrete and precast slabs, regardless of reinforcement density.
Attach the crown via the 5/4" UNC connection to a core drilling machine with dust extraction through the spindle. Activate the micro-percussion function and use a support stand for optimal results. Dust extraction is mandatory during operation to ensure performance and safety.
Does this crown require water during drilling? No. This crown is specifically engineered for dry drilling, eliminating the need for water when working in concrete.
Is dust extraction required? Yes. Dust extraction through the core drill spindle is mandatory for safe and effective operation.
What connection type does this crown use? It uses a 5/4" UNC thread connection, compatible with most standard core drilling machines.
Can it drill through heavily reinforced concrete? Yes. The crown is designed to handle all types of reinforcement — fine, thick, or variable density — in concrete and precast slabs.
Is a support stand necessary? While not strictly mandatory, using a micro-percussion function combined with a support stand is strongly recommended to achieve the best drilling results and accuracy.
