12D782 - Walter W217 Vitrified Mounted Point for Steel

Precision Grinding with Walter W217 Mounted Points

In the realm of industrial metalworking and maintenance, precision is paramount. The Walter W217 Mounted Point represents the pinnacle of abrasive engineering, designed specifically to meet the rigorous demands of fitting, enlarging, and finishing operations. Manufactured by Walter Surface Technologies, a leader in surface treatment solutions, this mounted point is crafted to deliver consistent performance on mild steel, cast iron, and high-tensile tool steels. Unlike generic abrasive stones that may suffer from eccentricity, Walter mounted points are meticulously balanced. This attention to concentricity ensures that the tool runs true, significantly reducing vibration. Less vibration not only protects the bearings of your pneumatic or electric die grinders but also reduces operator fatigue, allowing for longer periods of precise work without the numbness associated with inferior abrasives.

The W217 shape, featuring a 1-inch diameter and a 3/8-inch thickness, is particularly effective for surface blending and working within larger bores or recesses where a wider contact patch is beneficial. The abrasive composition is optimized for ferrous metals, ensuring that the grains fracture at a controlled rate to expose sharp new cutting edges continuously. This self-sharpening action prevents the glazing often seen in lower-quality points, maintaining a high material removal rate throughout the life of the product. Whether you are smoothing out a rough casting, enlarging a drilled hole to a precise tolerance, or deburring a machined part, the Walter W217 provides the control and finish required for professional results.

Durability is a core characteristic of the Walter line. The vitrified bond holding the abrasive grains is formulated to withstand the heat and stress of high-speed grinding without premature disintegration. This reliability makes it an essential consumable for tool and die shops, foundries, and general fabrication environments where downtime for tool changes needs to be minimized. By choosing Walter, you are investing in a consumable that respects the quality of your work and the longevity of your power tools.
