If you need to finish your steel surfaces accurately with a beast of a surface grinder attachment, this is it. The 1.5” tooling arm will fit it up to most grinders with standard (2") receiver tubes. Why is this one so great? It's made to fit the Revolution and comes with a Revolution-ready tooling arm and NEW 3-INCH WIDE contact wheel so your 2" belts will run flatter against your material, and also accommodate the 3x79 Tsunami Our surface grinder has switchable magnets, built on 5/8" thick aluminum plate to hold your work piece in place instead of a big magnet. So instead of having to slide your work piece off of a magnet [which can result in scratching your work], flip the 3 locks to release the magnets and your piece is released. Five roller linear rail (for rigidity) Simple (no tools required) tapering feature. NEW 3-INCH WIDE 8" contact wheel that can be used as just a contact wheel by removing sliding table. 19" of travel Everything you need to fit this up to your grinder comes standard, including the contact wheel & tooling arm (1.5" square tube) *Some assembly required** The SGA is a collab project, excluded from discount codes unless noted The Non-Ferrous Vise add-on: Finish your non-ferrous (wood, brass, plastic) surfaces accurately with our HouseMade surface grinder vise attachment.
