Carbide spiral flute reamer for valve seat guide machines has a high degree of concentricity, featuring cemented carbide material.
The most commonly used type is the helical flute: it offers smooth cutting, low vibration, high durability, excellen treaming hole quality, and can be used to process holes with discontinuous surfaces, such as keyways. Right-hand helical cutters are used for blind holes, with the cutting motion flowing out along the groove. Left-hand helical cutters have an axial force directed towards the handle, making the clamping secure and the cutting direction towards the surface to be machined, suitable for processing through holes
The groove type of carbide cutters: straight groove： easy to manufacture, generally requires use. Inclined groove： can improve processing conditions and enhance the quality of hole machining. The inclined direction should make the cutting flow towards the surface to be machined, avoiding cutting scratches on the already machined surface. Suitable for parts with high precision requirements for hole dimensions!
The spiral flute reamer is mostly used for machine-driven reamers. They are mainly employed in the mass production of parts. The working mode is rotational advancement type, so they are also called spiral advancement reamers. Compared with straight-edge reamers, they are more durable and have better processing accuracy and surface roughness.
