COMP Cams Valve Guide Cutting Tool Diameter

COMP Cams valve guide cutting tools, also called valve guide cutters, let engine builders machine cylinder head valve guide bosses to accept larger-diameter valve springs. Many modern high performance engines need springs larger than stock, and these cutters let you trim the head to fit the spring you are running.

Key Features:

• Made from high-strength steel with a carbide cutting bit for clean, accurate cuts
• Cuts the guide boss to a larger diameter for aftermarket valve guides and spring clearance
• Each cutter is sold individually
• Works with a COMP Cams arbor/pilot, which is sold separately
• Made in the USA by COMP Cams

COMP Cams has built valve train components since 1976. Its tools are made for professional engine builders and serious enthusiasts. Pair the cutter with the correct arbor/pilot for your valve stem size, and use cutting oil at a slower RPM for best results.
