HIGH SPEED STEEL REAMERS
TOOLS & COMPONENTS
KPMI® valve guide reamers are manufactured from premium hardened High Speed Steel. The advertised 昀椀nished reamer diameters are ground
to: +/- .0002”. These spiral 昀氀uted reamers incorporate a 1.00” long pilot (reduced diameter) which gets inserted into an un昀椀nished guide bore, to
align the reamer to the valve guide centerline, during the sizing process. These reamers have been speci昀椀cally designed for KPMI® Manganese
Bronze and Cast Iron valve guides. Do not attempt to use these reamers to size C630 Nickel Aluminum Bronze guides. Also, once a reamer is
used on Cast Iron, it is not advisable to then use it on a bronze guide.

SOLID CARBIDE REAMERS
KPMI® Carbide valve guide reamers are manufactured from Solid Carbide. All KPMI® reamers are ground to: +/- .0002”. KPMI® carbide
reamers are straight-昀氀ute and have a 6-昀氀ute design. The pilot portion of KPMI® reamers are 1.0” to 1.5” long. Insert the pilot into a guide that
you intend to size. Using a hand held drill, apply honing oil or ATF before and during reaming a guide. KPMI® reamers have been speci昀椀cally
designed for Manganese Bronze valve guides and Cast Iron. Do not attempt to use these reamers to size C630 Nickel Aluminum Bronze guides.
Also, once a reamer is used on Cast Iron, it’s not advisable to then use it on a bronze guide.
