Whole tungsten steel drill bit
The integral tungsten steel drill bit is suitable for use on advanced machining centers. The overall tungsten steel drill bit is made of fine-grained tungsten steel material. In order to prolong its service life, TiAlN coating treatment is also carried out. The specially designed geometric blade shape enables the drill bit to have self centering function, which has excellent chip control and chip discharge function when drilling large workpieces. The self centering function and strict control of manufacturing accuracy of this drill bit ensure the drilling quality of the hole, and there is no need for subsequent precision machining after drilling.
Adjustable blade drill bit
The drill bit with tungsten steel reversible blade can process a wide range of aperture sizes, with a processing depth range of 2D~5D (D is the aperture), and can be applied to lathes and other twisting machining machines.
Welded tungsten steel drill bit
Welded tungsten steel drill bit is made by smoothly welding a tungsten steel tooth crown onto a steel drill body. This type of drill bit adopts a self centering geometric blade shape, with low cutting force, and can achieve excellent chip control for most workpiece materials. The machined holes have good overall smoothness, high dimensional accuracy and positioning accuracy, and do not require further precision machining. This drill bit adopts an internal cooling system and can be used in machining centers, CNC lathes, or other high rigidity, high-speed machine tools.
Can replace tungsten steel crown drill bit
The replaceable tungsten steel crown drill bit is a new generation of drilling tool. It is composed of a steel drill body and a replaceable integral tungsten steel tooth crown. Compared with welded tungsten steel drill bits, its machining accuracy is about eight and a half pounds. However, because the tooth crown can be replaced, it can reduce machining costs and improve drilling productivity. This type of drill bit can obtain accurate increment of aperture size and has self centering function, with high precision in aperture machining.
