Regis Manufacturing Valve Guide Resizing Arbor Knurler

The Regis Manufacturing Valve Guide Resizing Arbor Knurler is a valve guide tool for engine rebuilders and machine shops. Knurling, also called valve guide knurling or guide resizing, restores worn valve guides to the correct bore size. This lets you reuse the original guides instead of replacing them. These arbors are also sold as valve guide knurlers and valve guide resizing arbors.

Key Features:

• Made of high-speed steel for durability in repeated shop use
• With proper care, Regis says its arbors and reamers will average 400 or more guides
• Regis states its replacement arbors and reamers are interchangeable with Winona, K-Line, Olcott, Hall-Toledo, Groove Rite and Hastings tooling
• Available in a range of sizes to suit different valve stem and guide diameters

Regis Manufacturing has been making tools since 1959. The tools are intended for professional engine machining and repair work, and they give a practical alternative to guide replacement.
