The blade is made of ultra-fine particle tungsten cobalt carbide alloy . The handle with a blade diameter of 0.10-3.175 is made of white steel, and the handle with a blade diameter of 3.20-6.50 is made of tungsten steel. Applicable equipment: PCB drilling machines, engraving machines, CNC and other high-precision specialized drilling equipment.
Processing scope: Drilling precision parts such as circuit boards, electric wood boards, plastics, amber, ceramic pearls and shells, organic glass, gold, silver, copper, and iron.
The raw material of the product is ultra-fine particle tungsten cobalt carbide alloy rod, which has the characteristics of high hardness, high wear resistance, high strength, bending and bending resistance, and long tool life.
Product features:
① Large chip removal space for drill bits: low chip removal resistance, smooth chip removal, low drilling heat generation, and reduced drilling pollution;
② Extraordinary cutting edge sharpness: Due to the use of nanotechnology and advanced grinding processes, the cutting edge of the drill bit is sharper than before, which can reduce cutting force, lower the rate of drill breakage, and improve the quality of the hole wall;
③ Tool design based on customer applications: There are a wide variety of drill bits that can meet different application needs. All parameters of the drill bit, such as core thickness, core taper, etc., have been carefully designed with significant effectiveness Strict symmetry of cutting edges: conducive to efficient cutting and avoiding drilling deviation.
