The roller is the main part of the roller bit.A drill bit is assembled and welded together by three teeth.The upper part is connected with screw threads for connecting with the drilling tool, and the lower part is made into a shaft neck with a certain tilt Angle, and the inner hole of the roller forms a bearing pair.The tooth palm has water hole runner, which can install oil storage pressure compensation device.Bearing the load of the shaft neck, it needs high wear resistance and hardness, at the same time, the internal matrix needs to have enough strength and impact toughness.

Main applications: roller foot is mainly used for assembling unconventional size bits, assembly bits, pile bits and reaming bits

It is a product produced and developed by our company. What is it used for?In fact, it is used to assemble a bit product parts, today our manufacturers mainly to introduce you is its assembly process.

In fact, the ball of a three-cone bit is just one of the parts of a cone bit. This product is mainly used for assembling with other parts to become a new assembly bit product. Then how is the assembly work done?This is where you have to use the welding process, the welding technology to put these products together.Not all materials can be welded, only metal products can be welded, our company's product is made of high-quality metal casting, so that its quality is reliable and durable.

At any time can consult our company, looking forward to your call!
