Borka Tools 1/4" to 5/16-27 Shotgun Brush Drill Adapter

The Borka Tools Shotgun Choke/Chamber Brush Adapter provides a practical connection between a cordless drill and compatible shotgun cleaning brushes, helping shooters address stubborn fouling in chambers and choke areas without relying entirely on manual scrubbing. One end features a standard 1/4-inch male hex drive that can be secured in a cordless-drill chuck, while the opposite end has a 5/16-27 female thread for properly matched shotgun cleaning accessories. Its chromium-vanadium steel construction gives the adapter the strength needed for controlled powered cleaning when paired with an appropriate heavy-duty brush. This configuration is particularly useful for breaking up accumulated plastic wad residue, carbon and other deposits that can become difficult to remove during routine shotgun maintenance. Brush selection is important because not every threaded cleaning brush is designed to withstand drill speed and torque. Borka Tools specifically recommends compatible Pro-Shot Payne Galway chamber brushes or a suitable direct-thread brush such as the Pro-Shot 12SB. Standard twisted-wire brushes equipped with brass threaded fittings should not be operated with this adapter under drill power, as those fittings are not intended for that application and may break during use. The adapter should be operated carefully and at an appropriate drill speed, with the cleaning brush selected for the firearm and maintenance task. Its compact, single-purpose design makes it easy to keep at the workbench or in a dedicated shotgun cleaning kit, while the common 1/4-inch hex connection eliminates the need for a specialized powered driver. This item includes the adapter only; the cordless drill, cleaning brush, solvent and other maintenance supplies are sold separately. It is a useful addition for shotgun owners, competitive clay shooters and gunsmiths who regularly clean heavily fouled chambers and choke tubes.
