Carbide straight flute reamer for valve seat guide machines is of high precision and has a high degree of concentricity, featuring cemented carbide material.
Straight flute: easy for manufacturing, inspection and grinding. This tool is mainly used for valve seat guide machines, drill the engine holes and remove the burrs from the holes.
Insert Standard 3/8 (9.52mm) Shank diameter UNI-PILOT in the cylinder head valve guide.Place checking gauge along pilot section that is exposed above cylinder head surface.If pilot top is within Min & Max range of the gauge, then you may proceed with machining seat.If pilot top is above Max range on gauge a smaller diameter pilot must be used.If pilot top is below Min range mark on gauge a larger pilot must be used.Checking Working Range of UNI-PILOT. Then use the carbide reamer to remove the burrs from the holes.
