Brownells #7 (W-170) Grinding Stone Refill 6 Pack delivers professional-grade grinding performance for precision gunsmithing work. Brownells “Premium Plus” stones are formulated with industrial grade cobalt 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.
These stones produce a smooth, ready-to-finish surface on all types of ferrous and non-ferrous metals. The stones resist filling and gouging and can be re-ground or re-shaped, lasting much longer than “hobby” grade points. Each grinding point features a hardened steel shaft that is nickel plated for long life and stays concentric even with repeated use.
The refill pack provides six replacement stones, making it easy to maintain your grinding point kit and keep your gunsmithing workspace well-stocked. The shank measures 1½” (3.8cm) long with 1/8″ (3.2mm) diameter. Whether you’re performing precision metal work, fitting components, or detailed gunsmithing tasks, these durable grinding stones deliver the cutting performance and finish quality you demand.
