OVERVIEW

High-Performance Zirconia Alumina Grinding Plug

The Walter 12C201 is a heavy-duty abrasive plug designed for the most demanding industrial grinding applications. Engineered with a premium Zirconia Alumina grain structure, this Type 18R plug delivers exceptional stock removal rates while maintaining a long service life. The coarse 16-grit composition makes it ideal for hogging off material, smoothing rough castings, and leveling heavy welds where speed and efficiency are paramount.

One of the standout features of this grinding plug is its integrated 5/8"-11 internal threaded arbor. This design allows for direct mounting onto straight grinders and die grinders without the need for separate collets or adapters, ensuring a secure fit and optimal concentricity. The direct mount system significantly reduces vibration, protecting both the tool bearings and the operator from fatigue during extended use. The 1-1/2" diameter and 3" length provide a substantial surface area for working inside pipes, cylinders, and other confined spaces that are inaccessible to standard grinding wheels.

Constructed with a robust resinoid bond, the 12C201 is formulated to withstand high pressure and heat generation. It is versatile enough to perform effectively on both mild steel and stainless steel, making it a staple in foundries, fabrication shops, and heavy manufacturing environments. Whether used for deburring, shaping, or heavy cleaning, this plug offers the aggressive bite required for rapid material removal.

FAQ

You need a straight grinder or die grinder equipped with a 5/8"-11 male spindle. The plug has a matching internal thread.

Yes, the Zirconia Alumina grain is suitable for use on both mild steel and stainless steel.

This plug is 16 grit, which is very coarse and designed for aggressive material removal.

It is a Type 18R plug, which features a cylindrical shape with a square end.

It screws directly onto the 5/8"-11 spindle of your grinder. Ensure it is tightened securely before use.

No, 16 grit is too coarse for finishing. It is intended for heavy stock removal and rough grinding.

While the thread might fit, these are designed for straight grinders. Using them on an angle grinder can be dangerous and difficult to control due to the orientation.

The integrated threaded arbor ensures excellent balance and concentricity, significantly reducing vibration compared to standard mounted points.
