When purchasing Brownells or any other brand from eGoods365.com store, you can be sure that (a) you are purchasing from US based company with the most responsive and friendly customer service; (b) an authentic, not a counterfeit and not a refurbished product.

Brownells offers the "Premium Plus" stones which are our highest quality option. By adding industrial grade cobalt to uniformly sized aluminum oxide crystals and bonding them with special, cool-running adhesives, we've created the hardest, longest-wearing, and fastest-cutting grinding points available to the trade. They are perfect for creating a smooth, ready-to-finish surface on all types of ferrous and non-ferrous metals without fillings or gouges. Additionally, they can be re-ground or re-shaped and last much longer than "hobby grade points". The hardened steel shafts are nickel plated for longevity and ensure concentricity even with repeated use.
We have selected our 10 most popular grinding points and included 3 of each in a convenient kit for you to store easily at home. Buying all 30 points at once will give you an exclusive discount as well. To keep your kit well stocked, we also offer economical refill 6-packs.
