• ABOUT BIHUI PRODUCTION MANUFACTURER:
Tile installation tool BIHUI is a premium quality product. BIHUI (Bihui or Bihai — complexity of translation from Chinese) despite its unusual name name releases advanced devices and fixtures for tile installers of excellent quality. BIHUI production, despite its Chinese origin, makes worthy 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 are supplied to Ukraine, and we are official dealers of this brand loops safely. On the base of our enterprise, a service center for warranty maintenance of BIHUI products has been created. Purchasing the product from us, you get a maximum warranty period of 12 months and original quality products that undergo mandatory testing and check inspection loops. There is nothing cooler on the professional tiling tools market of Ukraine in terms of price/quality ratio.
• RECOMMENDATIONS FOR CONDUCTING WORK OPERATIONS:
To obtain a high-quality hole cutout and extend the tool lifecycle of the core bit, it is required to select the optimal drilling rotation speed parameters, and also during drilling to conduct minor circular wobbling motions with the angle grinder or drill machine. Core bits do not require water feed cooling, as they are effectively cooled by the airflow generated by the angle grinder running at high rotation speeds (up to 14000 rpm), and they can be exploited at maximum revolutions with any materials. Core bits of small diameters overheat rapidly, and therefore it is better to drill multiple holes with a cooling pause cycle. If you want to extend the service life resource of these bits, then porcelain stoneware must be drilled at maximum revolutions and with additional cooling wax or water delivery, which will extend the tool lifecycle loops safely. Cooling wax costs money, sometimes quite substantial, and if the "toad chokes" you, a common standard paraffin candle wax block can be utilized tracking.
The BIHUI Dry Gres core bits are manufactured using VLS (Vacuum-Liquid Sintering) technology, which ensures the positioning of diamonds tightly next to each other throughout the entire volume volume of the diamond-bearing layer matrix. Due to this layout, BIHUI drills through at high speed rates and features a large resource lifespan loops tracking safely lines.
The vacuum-liquid sintering technology ensures adhesion of diamond grains to the metallic matrix bond comparable to brazing. Essentially, the grains are brazed to each other with a nano-layer of metal bond. Diamond grains cannot fall out of the metallic bond layer until they destroy themselves completely. Each single diamond grain is brazed tightly to at least three (up to nine) adjacent and underlying grains layers. Plus, the segment height height of the diamond-bearing layer is tens and hundreds of times larger than the single diamond grain diameter size. Once the top layer of diamonds is worn out — the next layer is fully exposed. Thanks to this framework layout, BIHUI possesses a high resource longevity fields track.
Advantages of the VLS (Vacuum-Liquid Sintering) Technology:
1. The concentration density of diamond grains is a hundred times higher than in any other alternative diamond tool. This allows increasing the operation speed execution by at least 3 times parameters.
2. Diamond grains are tightly pressed to each other and operate jointly. This substantially increases the dynamic and thermodynamic stability resistance of the diamond-bearing matrix segment layer.
3. Diamond grains are brazed with a metallic bond compound to each other. Due to this layout, the tool lifecycle resource is hundreds of times higher compared to any other standard diamond tool bits fields.
4. Tool geometry changes slower during operation wear compared to other analogues. This allows reducing the time spent on equipment reconfiguration setups and increasing overall workspace productivity.
5. Diamond grains inside the layer layout are positioned tightly with each other, precisely along the mold surface geometry. Thanks to this layout, the precision, roughness parameters, and overall quality of the processed surface section are increased by multiple times compared to powder metallurgy sintering technology, and tens of times compared to galvanic electroplated technology under an identical grain size mesh of the diamond powder mix safely loops.
• 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).
The total quantity and final quality of holes drilled with this tool will directly depend on the correct and safe utilization of the diamond instrument matrix.
• DESCRIPTION OF BIHAI DIAMOND CORE BITS:
We present to you the diamond core bits BIHUI, which are utilized for drilling any type of artificial cladding and large-format materials: ceramic tiles, porcelain stoneware, marble, glass sheets, granite, etc. During manufacturing of the BIHUI diamond core bits, the technology of vacuum brazing of diamond particles to the drilling zone area is applied. This technology significantly increases the resource lifecycle of core bits due to increased resistance to high temperatures and frictional forces. The diamond core bits BIHUI Dry Gres serve for dry drilling and are fixed directly onto the majority of grinders with M14 thread or to a non-impact drill machine (screwdrivers) using an adapter pin. The maximum drilling speed for cutting holes with BIHAI diamond core bits is around 14000 rpm lines layout track.
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 40 holes. For BIHUI Dry Gres core bits from Ø 20 to 75 mm, this resource corresponds to 80 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 maximum drilling depth with BIHUI Dry Gres core bits is 36 mm.
Inside small BIHUI core bits with diameters of 6mm, 8mm, 10mm, 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. To extend the service resource of the core bits, we recommend using diamond drill wax, which can be purchased inside our store layout track safely.
On large BIHUI core bits (diameters from Ø 20 to 75 mm), compensation slits slots are provided by the manufacturer, which contribute to extra cooling of the diamond core bit and removal of drilled material 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. To extend the resource lifespan on large core bits, cooling wax is also applied fields track safely loops.
• ADVANTAGES OF BIHUI DIAMOND CORE BITS:
