OVERVIEW

High-Performance Zirconia Sanding for Confined Spaces

The Walter Surface Technologies Topcut™ Sanding Disc (SKU: 04D306) is a premium abrasive solution designed for industrial maintenance, repair, and operations (MRO) professionals who demand efficiency and longevity. Engineered with high-quality Zirconia Alumina grain, this 3-inch disc delivers aggressive stock removal while maintaining a cool cutting action, making it an ideal choice for working with heat-sensitive materials like stainless steel and aluminum, as well as standard carbon steel.

One of the standout features of the Topcut series is the Twist-on (Type R) mounting system. This quick-change mechanism allows operators to swap out worn discs or change grit sizes in seconds without the need for additional tools, significantly reducing downtime in high-throughput environments. The 3-inch diameter is specifically sized to access hard-to-reach areas, such as inside corners, channels, and complex geometries where larger angle grinders cannot fit.

This specific model features a 60 grit abrasive, identified by its blue color-coded backing. This visual indicator simplifies inventory management and ensures operators select the correct aggressiveness for the task at hand. The 60 grit rating offers a versatile balance, capable of leveling welds and removing heavy burrs while leaving a surface finish that is easily refined. Whether used for deburring, blending, or general surface conditioning, the Walter Topcut disc ensures consistent performance and exceptional productivity.

Key Industrial Benefits

  • Extended Life: Zirconia grain outlasts standard aluminum oxide, reducing consumable costs.
  • Rapid Changeover: The plastic "TR" button ensures a secure fit and fast release.
  • Versatile Compatibility: Effective on ferrous and non-ferrous metals.

FAQ

This disc uses the Twist-on "TR" system, which is compatible with standard Type R (Roloc style) backing pads.

It is suitable for use on steel, stainless steel, and aluminum due to its cool-cutting Zirconia Alumina grain.

In the Walter Topcut system, the blue backing indicates that the disc is 60 grit.

You will need a pneumatic or electric die grinder equipped with a 3-inch Type R backing pad.

Yes, 60 grit is an excellent medium-coarse grade for leveling small welds and blending surfaces without gouging too deeply.

Zirconia is tougher and self-sharpening, meaning it cuts faster and lasts significantly longer than standard aluminum oxide discs.

Yes, the 60 grit is aggressive enough to strip paint and rust effectively from metal surfaces.

While specific RPM can vary by batch, these small diameter discs are typically rated for high-speed die grinders, often up to 20,000 RPM (always check the disc label).
