Tungsten carbide screw-tap compared with most turning, milling and drilling tools are different, tungsten carbide taps’ cutting edge are relatively weak, and the overall strength is lower. Even in the workpiece material is relatively easy to cut when machining, tungsten carbide screw-tap’s cutting edge is also prone to chipping, leading to tool failure. When the low carbon steel tapping, continuous long chips may clog the chip flute taps, thus limiting the number of Tungsten Carbide Screw-tap applied even more easily than the workpiece material tapping steel (such as aluminum and iron).

Steel and other iron-group material are the most common needs of processing and assembly with the screw holes in the material, therefore, tool manufacturers are sparing no effort to develop cutting edge to prevent chipping and breakage of taps. Given carbide and high speed steel can be compared with the innate superiority, and therefore Tungsten Carbide Screw-tap has become a developmental point.

Tungsten carbide screw-tap’s tapping process exist chip processing problems, due to the tungsten carbide material itself for it features high carbide hardness, brittleness. Tungsten carbide screw-tap’ unique features and characteristics of the manufacturing process design parameters, the use of advanced coating technology, the basic form of the performance characteristics of Tungsten Carbide Screw-tap.

Tungsten Carbide Screw-tap feature to strengthen and improve the wear resistance of the tip, the use of special grooves and cutting angle, while increasing the number of grooves to reduce the amount of each cutting tooth; to improve the wear resistance and anti-stick properties knife , using the TiAlN surface coating with excellent and stable chemical heat and chemical resistance.

There are several features of Tungsten Carbide Screw-tap, they are the followings:

Material: Consider the wear resistance and impact resistance under the premise of using ultra-fine particles of tungsten carbide. 

Shape: To improve rigidity, no-neck strengthening tap handle type.

Channel: to improve the wear resistance and good chips, using this matches the number of grooves and groove shapes.

Cutting angle: To increase rigidity and prevent chipping, using a special rake angle.

Accuracy: Given the contraction in the thread, using a modest increase size.

Cut length: consideration of the stability and longevity of the cut portion of the length defined in the five teeth.

Tip diameter: To ensure that the actual length of the cut, using a large tip diameter taps.

Due to tungsten carbide twist drill’s shape, the cutting edge features of each point shows the helix angle is changed, the tungsten carbide twist drill’s helix angle directly affects the anterior horn of the main cutting edge.

Tungsten carbide twist drill’s helix angle is larger, the more sharp edge, cutting more light, otherwise it will cause serious hardening phenomenon making the blade quickly wear. According to the relevant tool design data, taking tungsten carbide twist drill’s helix angle of 30 ° to meet the requirements, while allowing for mass production.
