What it is
The Breaker impregnated diamond core bit is the ideal solution for continuous drilling in high-strength materials such as reinforced concrete, old concrete and hard natural stone. Designed to deliver high performance and long life, this core bit suits professional requirements on building sites, renovations and work on existing structures. Its advanced abrasive technology ensures precise cuts and reduces working times, optimising productivity.
A TCT or diamond core bit is a core cutter for large-diameter holes in concrete, masonry, tiles and stone; this category includes arbors, adaptors and pilot drills.
What it is for
Used for core drilling concrete and masonry, for service openings and sampling, for drilling reinforced concrete, in hammer or rotary hammer mode and for running services through walls, floors and suspended ceilings.
How to use it
Fit the core bit to the arbor or adaptor suited to the machine, with the pilot drill to centre the hole. TCT core bits for masonry work with the rotary hammer in hammer mode, diamond core bits without hammer action, wet or dry depending on the type. Once the core bit has cut a groove, the pilot drill can be removed; continue with moderate pressure, withdrawing the tool frequently to clear the dust.
