We have identified premium-quality, smooth-cutting stones that provide an optimal combination of hardness, cutting speed and finish for shaping the ejection port roll-over notch on 1911 Auto slides. Begin with the B51 stone for either the short or long style notch and then use the B42 stone to achieve the full depth of the long style notch. These cobalt-impregnated aluminum oxide stones cut efficiently without gouging or tearing the metal, resulting in a smooth, ready-to-finish surface suitable for polishing or bead-blasting. The stones can be reground and reshaped, ensuring durability across multiple jobs. The hardened steel shanks are nickel-plated for extended longevity and maintain concentricity even after repeated use.

Composition - aluminum oxide matrix enhanced with cobalt infusion
Ejection port grinding stone kit, 120 grit
