Key points:

• These reamers have been specifically designed for KPMI® manganese bronze and cast iron valve guides.
• Also, once a reamer is used on cast iron, it is not advisable to then use it on a bronze guide.
• Do not attempt to use these reamers to size C630 Nickel Aluminum Bronze guides.
• All cutting diameters are +/- .0002".

Manufactured to tight tolerances and intended only for the specified guide materials; improper use can damage both the tool and the guide.
