Neway Valve Seat Cutters Standard Diameter
Neway valve seat cutters are not application specific - whether it's a high performance automotive engine, vintage motorcycle, or aircraft head, if the cutter fits and it's the correct angle, it's the right cutter. The unique carbide blades will machine any valve seat material, from the toughest to the softest.
Neway Standard Valve Seat Cutters
Precision Valve Seat Cutters
Neway Standard Series Cutters are built for precision valve seat reconditioning in automotive, diesel, and industrial engines. Designed to cover valve seats from 1-1/4″ to over 3″ in diameter, they deliver clean, concentric cuts with durable carbide blades and fixed cutting angles. Used with .375″ top-size pilots, these cutters provide exceptional stability and accuracy. Trusted by professional machinists and engine builders worldwide, Neway Standard Series offers reliability, versatility, and long-lasting performance for larger-scale valve seat work.
Small Cutters need Small Valve Guide Pilots
Neway Standard Series Cutters are designed to be used with .375" top-size pilots (140 Series Tapered Pilots, 150 Series Expandable Pilots or 200 Series Long Expandable Pilots), which provide the stability and alignment necessary for larger valve seat applications. These pilots fit directly into the valve guide, centering the cutter to ensure precise, concentric seat machining across automotive, diesel, and industrial engines. With a wide range of pilot diameters available, each matched to specific valve guide sizes, Neway ensures accurate alignment regardless of engine type. Manufactured for strength and durability, these pilots maintain their shape and precision through repeated use, making them an essential component for achieving professional-quality valve seat reconditioning.
Turning the cutters - more important than it seems
The Neway EZ Turn Wrench is engineered to deliver smoother, more precise control when operating valve seat cutters. Unlike traditional T-handles, the EZ Turn’s ergonomic design reduces operator fatigue and provides consistent, even pressure—essential for achieving perfectly concentric valve seats. Its integrated thrust bearing minimizes friction, allowing cutters to glide effortlessly while maintaining accuracy. This not only improves surface finish but also extends cutter life by reducing uneven wear. Compact and durable, the EZ Turn Wrench is especially valuable in tight engine bays and small-scale applications, making it the superior choice for professionals and DIY engine builders alike.
