What it is
The L300 Breaker frame is a robust, lightweight support designed to ensure maximum stability during coring operations with a diameter above 100 mm. Ideal for site applications, this frame ensures precision and safety, reducing vibration and making it easier to position the core drill. Thanks to its quick anchoring system, the motors are mounted simply and securely, optimising working time.
Core drilling equipment comprises diamond core bits, extensions, adapters, drill stands and water and dust extraction systems for core drills.
What it is for
Used for core drilling concrete and masonry, for service openings and sampling and for drilling reinforced concrete, in hammer or rotary hammer mode.
How to use it
Fit the core bit to the core drill using the adapter matching the thread, and secure the stand to the surface with an anchor or vacuum base. For wet coring, turn on the water before starting and keep it running throughout; for dry coring, connect the dust extractor. Start with light feed until the bit has cut a groove, then continue at steady pressure without forcing.
