Walter A-3 Grinding Point for Hardened Steel

Industrial Grade A-3 Mounted Point

For professional welders and MRO specialists, the Walter 12D011 A-3 Mounted Point represents the gold standard in bonded abrasives for hard metals. This tool is specifically formulated to tackle "tough steel" applications, including work on cast iron, tool steel, and high-tensile steel structures. In maintenance and repair operations, where fitting and enlarging holes to precise tolerances is a daily requirement, having a reliable abrasive point is non-negotiable.

The A-3 shape is a versatile profile in the die grinding world, offering a cylindrical body that is perfect for working inside bores, pipes, and tight corners. Walter's implementation of this standard shape utilizes premium abrasive grains that maintain a sharp cutting edge. This prevents the common issue of "glazing," where the stone becomes smooth and stops cutting, generating excessive heat. Instead, the Walter point breaks down at a controlled rate, constantly exposing fresh grain for cool, efficient grinding.

Performance and Durability

Durability is a key factor in the value of the 12D011. The bonding agent used is tough enough to withstand the high RPMs of industrial die grinders without disintegrating, yet friable enough to self-sharpen. This balance makes it ideal for heavy-duty tasks such as cleaning up welds in hard-to-reach areas or modifying hardened steel dies. Furthermore, the precise concentricity of the point ensures that it runs true, providing a high-quality surface finish without chatter marks.

Equip your shop with Walter A-3 Mounted Points to experience the difference that high-quality manufacturing makes. From reducing downtime spent changing worn-out stones to improving the accuracy of your fitting work, this product is built to perform under pressure.
