OVERVIEW

Precision Grinding for Industrial Applications

The Walter Surface Technologies 12D121 A-38 Mounted Point is a high-performance abrasive tool designed for the rigorous demands of industrial metalworking. Engineered specifically for tough steel, cast iron, and high tensile alloys, this mounted point delivers consistent material removal rates and superior surface finishes. In MRO and fabrication environments where precision is paramount, the A-38 shape (cylindrical) proves essential for tasks such as enlarging holes, fitting mechanical parts, and smoothing internal surfaces of castings.

One of the defining characteristics of Walter's mounted points is their manufacturing quality. Each point is meticulously balanced to ensure perfect concentricity. This attention to detail significantly reduces vibration during operation, which not only improves the quality of the work but also extends the lifespan of the pneumatic or electric die grinder being used. Excessive vibration is a common cause of bearing failure in power tools; by choosing Walter, you protect your equipment investment while achieving better results.

The abrasive composition is formulated to resist glazing, even when working on hard materials like tool steel. This ensures that the point maintains its cutting action throughout its life, reducing the frequency of dressing or replacement. For workshops handling diverse metal grades, the 12D121 offers a reliable solution for detailed grinding tasks where larger wheels cannot reach.

FAQ

The A-38 is a cylindrical mounted point, typically measuring around 1 inch in diameter and 1 inch in length, ideal for working inside holes or against flat surfaces in tight spots.

This specific point is formulated for tough steel and cast iron. Using it on soft non-ferrous metals like aluminum may cause the abrasive to load up (clog) quickly. A wax or lubricant would be needed, but it is not the primary recommendation.

The 12D121 is designed for use with a die grinder (either pneumatic or electric) that accepts the shank size of the mounted point.

A balanced point prevents the tool from vibrating or 'chattering.' This ensures a smoother finish on the metal, prevents damage to the die grinder's bearings, and reduces operator fatigue.

While it can grind stainless steel, it is optimized for 'tough steel' and cast iron. For dedicated stainless steel work, verify if a contaminant-free (Fe-free) abrasive is required for your specific application standards.

You can use a dressing stone or a diamond dresser to true up the face of the mounted point and expose fresh abrasive grains if it becomes glazed or misshapen.

Always wear impact-resistant eye protection (safety glasses and a face shield), hearing protection, and appropriate gloves. Ensure the tool's speed does not exceed the maximum RPM rating of the mounted point.
