Brownells “Premium Plus” stones are the very finest available, and this #1 (B-45) Grinding Stone Refill 6 Pack delivers professional-grade grinding performance for gunsmithing and precision work. Industrial grade cobalt is added to uniformly sized aluminum oxide crystals and bonded with special, cool-running adhesives to form the hardest, longest-wearing, fastest-cutting grinding points available to the trade. These stones give a smooth, ready-to-finish surface on all types of ferrous and non-ferrous metals and resist filling and gouging; they can be re-ground or re-shaped, lasting much longer than “hobby” grade points.
The hardened steel shafts are nickel plated for long life and stay concentric even with repeated use. The shank measures 1½” (3.8cm) long and 1/8″ (3.2mm) in diameter, making these stones compatible with standard rotary grinding tools. This economical Refill 6-Pak makes it easy to keep your kit well stocked. Whether you’re performing precision finishing on actions, receivers, or fine detail work, these refill stones deliver the durability and smooth finishing action serious gunsmiths demand.
