Product DescriptionProduct DescriptionPCB Diamond Knife products&Solid tungsten steel V-CUT knife 1.V-Cut Processing:It can cut V-grooves on PCB boards to facilitate subsequent board separation. Its high hardness can ensure that the V-grooves have clear contours and stable dimensions, and can efficiently process copper-clad boards containing glass fiber.2.High-precision scribing and cutting:For precision cutting or slotting of semiconductor packaging components, it is recommended to use ultra-thin diamond dicing knives or cutting blades.3.Their extremely thin thickness (such as 0.23mm to 0.5mm) can achieve high-precision, small cutting depth processing and effectively reduce cutting tilt and edge collapse4.Cutting and edging:Diamond circular saw blades (such as polycrystalline diamond circular saw blades) can be used to cut PCBs, and can be designed to complete cutting and edge grinding at the same time, pursuing high efficiency and burr-free5.Milling contours and slots:This is the home of the whole tungsten steel milling cutter, especially suitable for processing the outer contour of the PCB, such as the slot hole, etc.Its excellent toughness can withstand interrupted cutting and impact in milling6.Micro-hole drilling:Very small diameter PCB micro drill bits are usually made of tungsten steel rods,Its high strength and rigidity ensure stability when drilling micro holes at high speedPCD SAW BLADEDiamond saw blade (also known as diamond saw blade) is a high-efficiency cutting tool with diamond particles embedded in the blade head. With the unparalleled hardness of diamond, it is specially used for cutting various hard and wear-resistant materials.High hardness, high wear resistance, high cutting efficiency, and long service lifecutting material:Masonry, concrete(including reinforced) natural stone Marble, granite Ceramics Glass, carbon fiber, Carbide, etc.Thick steel core enhances stability. Laser-cut silencers reduce noise and vibration.
