Set of 5 core drill bits BIHUI (diam. 6, 8, 10, 12mm with M14 adapter) in CASE

DESCRIPTION:
Core bit dimensions in the set: 6/8/10/12mm + adapter from M14 to straight shank for drill machine

The diamond core bits BIHUI Dry Gres are recommended for drilling any type of ceramic tiles, especially porcelain stoneware, as well as other cladding materials such as marble and granite. During manufacturing of the BIHUI Dry Gres diamond core bits, the technology of vacuum brazing of diamond particles to the drilling zone area is applied, which increases resistance to high temperatures and friction and significantly increases the resource lifetime of the core bits. The diamond core bits BIHUI Dry Gres serve for dry drilling and are fixed directly onto the angle grinder shaft using M14 thread or to a non-impact drill machine with the use of the included adapter. The maximum drilling speed with diamond core bits DRYGRES is around 14000 rpm.
The average resource lifetime of the BIHUI Dry Gres core bits varies depending on their diameter. For core bits from Ø 6 to 12 mm, the average resource is 25 holes.
For BIHUI Dry Gres core bits from Ø 20 to 75 mm, this resource corresponds to 50 holes.
The average resource of core bits ALWAYS depends on the type of material being drilled, its thickness parameters, and the correctness of drilling and cooling of the core bit. The drilling depth with BIHUI Dry Gres core bits is 36 mm.
Inside BIHUI Dry Gres core bits of Ø 6, 8, 10, and 12 mm, cooling wax is contained. During usage of the core bits, the wax melts down and improves its cooling and removal of drilled sludge slurry layers. After melting all the wax, you can continue working with the core bit loop tracks safely. Only complete consumption of the diamond layer indicates the end of the core bit lifespan runtime.
On the BIHUI Dry Gres core bits (diameters from Ø 20 to 75 mm), there is a side slot opening, which improves cooling of the core bit, and the removal of drilled material substrate from its inner section area after each drilled hole loop. Before each new drilling cycle, it is necessary to make sure of core bit cleanliness and absence inside it of previously drilled material or other foreign objects structures layers.

Diamond brazed segment height 10mm
Large resource lifespan thanks to vacuum brazing and high premium grade quality of diamond crystals layer
Affordable price parameters

DRILLING FEATURES SPECIFICS:

Water feed delivery is not required (however extra cooling with water or cooling wax increases diamond drill bit lifespan), cooled due to air flow stream generated by angle grinders at high speeds.
Drilling is conducted strictly via non-impact method loop tracks safely.
Starting the drilling cycle is required via a template guide matrix, or under an angle of 45 degrees to avoid core bit skidding deviation off the workpiece surface, gradually, executing circular wobbling movements transition the bit into a perpendicular 90° position relative to the drilling plane lines.
IMPORTANT: drilling without water cooling or a special cooling wax compound cuts short the lifecycle of your diamond drill core bit by more than 2 times, and in case of overheating, a "glazing" effect occurs, and the drill bit may completely stop cutting through. If this occurs, it is required to "open" or "sharpen" the bit using a soft abrasive material block (an abrasive sharpening bench stone, asphalt, or a firebrick block is the best option lines loop track safely).
Remember! The total amount and quality of holes will rely on how correctly you exploit the diamond core bit matrix tools fields safely.
