BROWNELLS ENGINE TURNING BRUSHES

The Brownells Engine Turning Brushes are specialized gunsmithing and metal-finishing tools designed to create attractive engine-turned, jeweling, or swirl-finish patterns on firearm bolts, receivers, floorplates, and other metal components. These brushes allow gunsmiths, firearm customizers, and metalworking enthusiasts to reproduce the distinctive decorative finish commonly found on custom firearms, classic bolt-action rifles, and precision-machined metal parts.

Engine turning is both decorative and functional, helping create a professional custom appearance while also retaining lubricants on certain firearm components. These brushes are designed to produce consistent circular patterns and are ideal for restoring original finishes, creating custom firearm accents, or enhancing the appearance of metal surfaces.

Use with 120 grit Silicon Carbide Abrasive and Do-Drill. Drill press rpm should be fairly high. The gunsmiths recommending this process praise it highly.
