12D056 - Walter A-21 Vitrified Mounted Point for Die Grinders

Precision Grinding for Demanding Metallurgy

The Walter A-21 Mounted Point (SKU: 12D056) represents the pinnacle of abrasive engineering for precision metal removal. Designed specifically for industrial environments where accuracy and surface integrity are paramount, this mounted point is formulated to tackle the unique challenges posed by tough steel, tool steel, and high-tensile alloys. In the realm of MRO and fabrication, the consistency of your abrasive consumables directly correlates to the quality of the finished part and the longevity of your power tools. Walter Surface Technologies has addressed these needs by creating a mounted point that offers exceptional structural integrity and cutting performance.

One of the critical differentiators of this product is its manufacturing tolerance regarding balance. A common issue with inferior mounted points is a lack of concentricity, which leads to severe vibration at high RPMs. This vibration not only results in a poor surface finish—often characterized by chatter marks—but also accelerates wear on the spindle bearings of pneumatic and electric die grinders. The Walter A-21 is impeccably balanced to ensure a smooth, vibration-free operation. This allows the operator to maintain precise control over the material removal process, essential when performing delicate fitting or enlarging operations in mold making or machinery repair.

The abrasive composition is tailored for "tough steel," meaning it possesses the friability and hardness necessary to cut hard metals without glazing over instantly. The vitrified bond holds the grain securely, allowing for a consistent breakdown rate that exposes fresh cutting edges as the tool works. This self-sharpening action is vital when working on cast iron or high-tensile steel, where heat generation must be managed to prevent metallurgical changes in the workpiece. The A-21 shape itself is a standard geometry widely utilized for its versatility, capable of grinding inside bores, cleaning up fillet welds, and smoothing out irregular contours that larger grinding wheels simply cannot reach.

Incorporating the Walter A-21 into your abrasive inventory ensures that your team is equipped to handle complex finishing tasks with efficiency. Whether the application involves deburring machined parts, blending weld seams in confined spaces, or preparing surfaces for final polishing, this mounted point delivers reliable, high-performance results. It stands as a testament to Walter's commitment to quality, providing a solution that reduces downtime associated with tool changes and equipment maintenance while maximizing material removal rates.
