Kibblewhite Precision Machining provides these specialized valve guide reamers, essential for precision engine work on Harley-Davidson cylinder heads. Manufactured from hardened High Speed Steel, these tools feature spiral flutes and a one-inch reduced diameter pilot to ensure perfect alignment with the valve guide centerline. Ground to a strict tolerance of +/- .0002 inches, they are specifically designed for sizing Kibblewhite Manganese Bronze and Cast Iron guides. Note that reamers used on cast iron should not be reused on manganese bronze, and these are not suitable for C630 nickel aluminum bronze. Kibblewhite is a trusted name in valvetrain components, offering the accuracy needed for professional-grade engine rebuilding.
