Tungsten carbide twist drill’s main geometric parameters include relevant handling drill corner selection, choose angle and the angle of the cutting edge before the drill, impact drill helix angle of the drill-life analysis and cutting edge.

The width of the tungsten carbide twist drill’s drill cuttings and drill apex decision anterior horn size. When the bit diameter and a certain amount of feed when the angle is increased, the iron is narrowed, the cutting edge of the unit load is reduced.Vertex has a great influence on the rake angle, a corresponding increase in the apex angle cutting conditions conducive to improving terrible at. Angle on the direction of chip flow. According to the relevant tool design data, combined with the hardness of the processed products is not high, but the viscous characteristics, select the tungsten carbide twist drill’s drill apex angle of 140 °.

Tungsten carbide twist drill is to adapt to the automotive industry and the IT industry high-efficiency machining of glass fiber reinforced plastics processing circuit board (PCB) needed to rapidly develop.

When drilling on the PCB, the exit hole requires no glass fiber nap. With the miniaturization, the diameter of the tungsten carbide drill direction will be small computers and mobile phones development, has a diameter of 0.08mm tungsten carbide twist drill.

There are several major tungsten carbide twist drill’s auxiliary planes, involving flat base surface, cutting plane, the profile and column profiles.

If the movement is not considered, tungsten carbide twist drill’s head base surface at any point on the main cutting edge due to the characteristics of the structure of tungsten carbide twist drill, the base surface of the drill point of the cutting edge is varied.

Cutting plane at any point on the main cutting edge, the cutting direction is included but the point cut in the plane of the point of the machined surface. Cutting plane and perpendicular to the base surface, and on the main cutting edge of the cutting plane of the points are not the same. The main cutting edge of the column cross-section at any point through the center-line of the drill point and to make the center line of the cylindrical surface of the main cutting edges of different columns of different cross-sectional surface of the cylindrical radius.

Owning to its excellent properties of tungsten such as high density with small volume, high melting point, excellent hardness, superior wearing resistance, high ultimate tensile strength, high ductility, gold-plated tungsten alloy rod and tungsten alloy golden rod could be regarded as the special present for some fields.

 Gold-plated tungsten rod, tungsten alloy golden rod have similar surface of gold, which is smooth and bright as copper mirror, which it is able to reflect the images next to it. With the similar gold color, it is usually very attractive and pleasant to eye, and be fond of many people.
