Adopting the latest “ Multilayer Vacuum Brazed Technology ”, JDR Multilayer Vacuum Brazed Router Bits are the best bits on the market. Compared with the sintered router bits , they achieve a longer life and have much faster profiling on granites and engineered stones. These diamond router bits are versatile and will perform well, when used with water on most portable routers with speeds ranging from 5,000 to 11,000 RPM. Both M8 and M10 bolts are included to fit all standard portable stone routers . It includes Position #1 bits in the most popular profiles: Full Bullnose, Demi-Bullnose, Ogee and etc. for 3cm(1-1/4”) or 2cm(3/4”) material. Diamond router bit

Symptom: Diamond segment Loss Cause:Overheating can usually be detected by blue color on steel center and generally confined to the area where the segment was lost. Remedy:Check the water system for blocked water passages. Test pump to see if it is functioning. For dry cutting, it may be necessary to make shallower cuts and allow the blade to run freely every few minutes in order to let the air cool it. Diamond segment

Vacuum Brazed diamond hole saw Vacuum Brazed diamond drill bit can be used on drilling machine. They are widely used in drilling and cutting marble,granite,ceramic,tiles,etc.

Symptom:Eccentricity Cause:If the diamond blade shaft bearings are worn, the shaft and mandrel will run eccentrically, causing the blade to wear out-of-round. This happens most often with concrete saws when proper lubrication of the bearings is neglected. Remedy:Install new diamond blade shaft bearings. In some cases it might also be necessary to replace the blade shaft if it is worn or out of alignment. Diamond blade

Symptom: Diamond segment loss Cause:Worn diamond blade flanges fail to provide proper support and cause the blade to deflect. Remedy:Replace both blade flanges. Hot pressed diamond blade

Symptom:Loss of diamond segments Cause:The material slips during cutting which twists or jams the segments loose. Remedy:Hold the material securely while cutting. Diamond blade To Be continued
