Wehrs Machine Tubing Notching Tool

Wehrs Machine Tubing Notching Tools: Purpose-Built for the Race Shop

When it comes to fabricating a race car interior, the details matter. Fitting aluminum body tin cleanly around roll cage tubing is one of those tasks that separates a professional-looking build from a rough one — and it's exactly the kind of problem that Wehrs Machine & Racing Products set out to solve. Tubing notching tools from Wehrs Machine are designed specifically for the circle track fabricator who needs clean, repeatable results without a machinist's full tool room.

Designed on the Race Track, Built in the USA

Since 1997, Wehrs Machine & Racing Products has been innovating products for the racing industry, operating as a circle track parts manufacturer specializing in suspension components, tools, and technology. As a manufacturer of quality aftermarket racing products, every Wehrs tool is proudly made in the USA. That race-shop DNA shows up directly in their notching tools, which were clearly engineered by people who have actually wrestled with interior tin on a Saturday night car.

The Interior Tin Tube Notcher Line

Wehrs Machine's tin notchers make fitting .040 aluminum around round tubing quick and easy. The line includes individual notchers in four sizes — 1", 1-1/4", 1-1/2", and 1-3/4" — covering the most common roll cage tube diameters found in hobby stock, street stock, and modified race cars. The Vise Grip-style pliers feature hardened jaws that make a full 180-degree cope , producing a clean, half-round cutout in a single squeeze. The longer handles increase leverage , reducing hand fatigue during a full day of panel fitting.

Available in 1-1/4", 1-1/2", and 1-3/4" inch sizes, these tools are perfect for fabricating race car bodies and interiors. For shops working across multiple tube sizes, a kit is available that includes all four sizes — 1", 1-1/4", 1-1/2", and 1-3/4" — in a single package.

What Sets Wehrs Machine Notchers Apart

• Hardened jaws: Designed to quickly and cleanly cut a notch in .040 aluminum without deforming the surrounding material.
• 180-degree cope in one step: The hardened jaws make a full 180-degree cope , so no secondary trimming or filing is needed for a flush panel fit.
• Multiple size options: Available in 1.25-inch, 1.5-inch, and 1.75-inch sizes (plus a 1-inch option), ensuring compatibility with the widest range of tube diameters in a typical race car chassis.
• Backed by a warranty: Each notcher comes with a 1-year manufacturer's warranty , reflecting Wehrs Machine's confidence in their construction quality.
• Made in the USA: Wehrs Machine crafts a variety of short track suspension components, accessories, engine parts, and tools — all made in the USA.
