Walter A-32 Vitrified Mounted Point for Steel and Cast Iron

Smooth Running Stones for Tough Jobs

When you are cleaning up a weld in a tight corner or trying to open up a hole in a piece of heavy plate, you need a grinding stone that cuts fast and runs smooth. The Walter A-32 Mounted Point (12D091) is built exactly for that purpose. If you have ever used a cheap grinding stone that wobbles and shakes your die grinder, you know how frustrating and tiring it can be. Walter solves this problem by ensuring every single point is expertly balanced before it leaves the factory. This means when you pull the trigger on your die grinder, the stone spins perfectly true, giving you total control over the grind and leaving a much smoother finish.

This specific point is designed for "Tough Steel," which means it eats up materials that usually wear out other stones. It works exceptionally well on cast iron, tool steel, and high-tensile alloys. The grain structure is aggressive enough to remove stock quickly for fitting and enlarging tasks, but it runs cool enough to keep you from burning the metal. The A-32 shape is a favorite in many shops because its bullet-like nose lets you get into curves and holes easily, making it perfect for cleaning up inside pipe fittings, smoothing out flame-cut edges, or prepping a surface for welding in hard-to-reach spots.

Durability is another key feature. Nobody likes having to stop every few minutes to change out a worn-down bit. The vitrified bond on this Walter point holds the abrasive together tightly, ensuring the shape lasts longer even under heavy pressure. It fits standard die grinders with a 1/4" collet, making it a plug-and-play upgrade for your tool crib. Whether you are a pipefitter, a mold maker, or a general welder, keeping a few of these high-quality stones in your box ensures you are ready for those detailed finishing jobs that a 4.5-inch grinder just can't handle.

Stop fighting with vibration and chatter. Upgrade to Walter mounted points and feel the difference in control and finish quality. It’s the small detail that makes a big difference in your daily grind.
