BC Series Flex-Hone are manufactured by Brush Research (BRM). The BC Series Flex-Hone tool is designed for use on any type or size of valve
guide from 4mm up to 3/8" in diameter. This guide hone is designed for surface 昀椀nishing and cross hole deburring. Although Ball Hones have many
uses, KPMI® o昀昀ers them primarily to be used after a guide has been reamed. Using a Ball Hone after reaming creates a uniform surface free of
irregularitys, which improves surface contact and reduces the risk of galling or seizure. Please see our FAQ for recommended clearances.

valve guide reamer
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 beaen 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.

valve guide reamer
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.
