Welcome to CalValves.com
For more than twenty five years CalValves has remanufactured numerous types of combustion engine valves from light duty automotive to heavy duty locomotive and everything in between! Our in-house hard chrome plating along with our non-destructive testing gives our customers a competitive edge by restoring serviceability to their OEM valve cores.
Our customers are leaders in the mining, locomotive, construction, agricultural, OTR, marine, and automotive engine remanufacturing business.
Custom Engine Valve Guide Reamers
Our standard reamer is made from solid carbide. It has six staggered flutes with a left-hand spiral, right-hand cut. The standard reamer is approximately 200 mm long overall with 100 mm long flutes. The pilot is about 30 mm long. The standard shank is cylindrical. Optional tool pickup shanks are available. The customer normally specifies the cutting (O.D.) diameter as well as the pilot diameter based on the reaming method (wet, semi-wet or dry) being used.
