•ABOUT THE MANUFACTURER BIHUI:

BIHUI tile laying tool is a premium quality product. BIHUI, despite its unusual name, manufactures advanced devices for tile installers of excellent quality. BIHUI production, despite its Chinese origin, makes decent, advanced tools on par with premium brands like Montolit, Sigma, RUBI, and supplies its products mainly to the USA and Europe. Since 2021, BIHUI tools have been supplied to Ukraine, and we are the official dealers of this brand. A warranty service center for BIHUI products has been established on the basis of our enterprise. By purchasing the product from us, you get a maximum warranty period of 12 months and original high-quality products that undergo mandatory testing and verification. There is nothing better on the Ukrainian professional tiling tool market in terms of price/quality ratio.

•RECOMMENDATION FOR WORK EXECUTION:

To obtain a high-quality hole and extend the service life of the core bit, it is necessary to choose the optimal drilling speed, as well as perform small circular movements with the angle grinder or drill during drilling. Core bits do not require water cooling, as they are cooled by air, the flow of which is created by the angle grinder at high speeds (up to 14000 rpm), and they can be operated at maximum speeds with any materials. Core bits of small diameters overheat quickly, so it is better to drill many holes with a pause. If you want to extend the service life of these core bits, porcelain stoneware needs to be drilled at maximum speeds and with additional cooling wax or water; this will extend the service life. Cooling wax costs money, sometimes a lot, and if you are reluctant to spend, you can use a regular paraffin candle.

BIHUI Dry Gres core bits are manufactured using VJS (Vacuum fluid sintering) technology, which ensures the placement of diamonds close to each other throughout the volume of the diamond-bearing layer. Thanks to this, BIHUI drills at high speed and has a long lifespan.

Vacuum fluid sintering technology ensures diamond grain adhesion to the metal bond comparable to brazing. In essence, the grains are fused to each other by a nano-layer of metal. Diamond grains cannot fall out of the metal bond until they break themselves. Each diamond grain is fused tightly to at least three (up to nine) neighboring and lower grains. In addition, the height of the diamond-bearing layer is tens and hundreds of times greater than the diameter of the diamond grain. Once the top layer of diamonds is worn out, the next one is exposed. Thanks to this, BIHUI has a high lifecycle.

Advantages of VJS (Vacuum fluid sintering) technology:

1. Concentration of diamond grains is a hundred times higher than in any other diamond tool. This allows increasing the speed of operations by at least 3 times.

2. Diamond grains are tightly pressed against each other and work together. This significantly increases the dynamic and thermodynamic stability of the diamond-bearing layer.

3. Diamond grains are fused together with a metallic bond. Thanks to this, the tool lifecycle is hundreds of times higher compared to any other diamond tool.

4. The tool geometry during operational wear changes more slowly compared to any other analogues. This reduces the time for equipment reconfiguration and increases productivity.

5. Diamond grains during the laying process are arranged tightly with each other, evenly along the surface of the mold. Thanks to this, the accuracy, roughness, and overall quality of the processed surface increase significantly compared to powder sintering technology, and tens of times compared to galvanic sintering technology with the same grit size of diamond powder.

•DRILLING FEATURES:

Water supply is not required (however, additional cooling with water or cooling wax increases the resource of the diamond drill), they are cooled by the air flow created by the angle grinder at high speeds.

Drilling is performed in a non-impact manner.

It is necessary to start drilling with the help of a template, or at an angle of 45 degrees to avoid the drill slipping from the surface of the processed material, gradually making circular movements to transfer the drill into a perpendicular position relative to the drilling plane.

IMPORTANT: drilling without water cooling or special cooling wax shortens the life of your diamond drill (diamond core bit) by more than 2 times, and in case of overheating, the "glazing" effect occurs, the drill may completely stop drilling. If this happens, it is necessary to "open" or "sharpen" the drill using a soft abrasive material (an abrasive grinding stone, asphalt, or the best option would be a firebrick).

The count and quality of holes drilled with this tool will depend on how correctly you use the diamond tool.
