OVERVIEW

Slice Through Steel with the Pferd 69947

When you are under the hood and need to make a quick, clean cut, you don't want a wheel that bogs down your grinder or wanders off the line. The Pferd 69947 4-1/2" Cut-Off Wheel is built for welders who need reliability and speed. With a thickness of just .040 inches, this wheel is a true "slicer." It glides through steel brackets, tubing, and plate with minimal effort, letting your grinder maintain its RPMs for a smooth, aggressive cut. The thinner profile also means you aren't turning valuable metal into dust—you're just separating it cleanly.

This wheel uses a tough Aluminum Oxide abrasive that is specifically tuned for carbon steel applications. Whether you are cutting out old welds, sizing stock for a fit-up, or trimming angle iron, the Pferd 69947 delivers a bite that lasts. It features a Type 1 flat center, which is preferred by many fabricators for making straight, deep cuts without the interference of a depressed center hub. This design allows you to utilize more of the wheel's diameter, getting the most value out of every disc.

Pferd is known for consistency. You won't find soft spots or wobble in these wheels. They run true and cut cool, which helps keep your workpiece from overheating and warping—a huge plus when working on thinner gauge materials. Pair this wheel with your favorite 4.5-inch grinder and experience the difference a premium abrasive makes in your daily fabrication tasks. Remember to always use a proper guard and safety gear when using cut-off wheels.

Why Welders Choose This Wheel

  • Fast Action: The .040" thickness cuts faster than standard 1/16" or 1/8" wheels.
  • Clean Cuts: Leaves minimal burrs, reducing cleanup time before welding.
  • Reliable: Consistent wear rate means no surprises during a critical cut.

FAQ

A .040 inch wheel is thinner than standard cutting discs. This thin profile removes less material, resulting in less friction, faster cutting speeds, and less heat buildup in the metal.

No, this is a Type 1 cut-off wheel designed strictly for cutting (using the edge). Using it for side grinding is dangerous and can cause the wheel to shatter. Always use a Type 27 grinding wheel for surface grinding.

While it can cut stainless, this specific wheel is optimized for carbon steel. For stainless steel, it is recommended to use a wheel specifically marked for stainless (often labeled INOX) to prevent contamination and ensure better performance.

Type 1 refers to the shape of the wheel. A Type 1 wheel is completely flat, unlike a Type 27 wheel which has a depressed center. Type 1 wheels are ideal for deep, 90-degree cuts.

Always wear a face shield over safety glasses, heavy gloves, and flame-resistant clothing. Ensure the angle grinder has a proper guard installed and positioned correctly.

The arbor size is 7/8 inch, which is the industry standard for most 4-1/2 inch, 5 inch, and 7 inch angle grinders.

Yes, all abrasive wheels have a maximum RPM rating printed on the label. Ensure your grinder's no-load speed does not exceed the RPM rating of the wheel (typically around 13,300 RPM for 4.5" wheels).
