Performance advantage

Material: integral tungsten carbide, welded type (SUS304SUS316+ Tungsten carbide alloy), SUS304 ensures no rust and high toughness; The welding agent is divided into brazing and silver welding.
Grade: Depending on whether the grinding material is water-based or oily, YG and YN medium/ultrafine particles are recommended, which can be customized.
Appearance: mirror-polished R0.4, hexagon/chamfer/withdrawal slot/wrench position/positioning hole/top round head/top flat head with drawings.
Thread :CNC machining, good thread concentricity, since M4, standard pitch/coarse/fine teeth, easy to install; There are no welds, missing welds or falling off at the joints.
Quality inspection: product quality inspection specifications, according to the standard torque test; The weight of the finished product is consistent, and the motor runs more stable.
