OVERVIEW

Smooth Control for Detailed Metalwork

When you are working in tight corners or trying to get a perfect fit on a metal part, control is everything. The Walter A-38 Mounted Point (12D121) gives you exactly that. Designed for welders and fabricators who need to clean up castings, enlarge holes, or smooth out rough edges on tough steel, this grinding stone is a cut above the rest. If you have ever used a cheap mounted point that wobbles and chatters, you know how frustrating it can be. Walter solves this with a perfectly balanced point that runs smooth and true right out of the box.

The A-38 shape is a classic cylinder, making it incredibly versatile for getting inside pipes, holes, or recessed areas. Because it is built with high-quality abrasive grains, it bites into the metal rather than just rubbing against it. This means you can grind down welds or imperfections on cast iron and high-tensile steel without applying excessive pressure. Less pressure means less heat buildup and less fatigue for your hands and wrists at the end of the day.

Whether you are doing precision die work or just cleaning up a fabrication project, this mounted point helps you get a professional finish. It holds its shape well and doesn't crumble under load, giving you the confidence to tackle detailed grinding jobs. Pop this into your die grinder and experience the difference a premium abrasive makes.

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.
