What power tools and drive interfaces are compatible with the Borka Tools ADPT-SHTGN adapter?

The ADPT-SHTGN features a standard 1/4-inch male hex shank designed to fit directly into any standard cordless drill, power screwdriver, or manual 1/4-inch hex handle commonly available in Australia. The output side is a #5/16-27 female thread engineered specifically to accept standard shotgun chamber and choke tube brushes across 12 GA, 16 GA, 20 GA, 28 GA, and .410 GA.

Can I use standard twisted wire bore brushes with this high-speed motorized adapter?

No, the manufacturer explicitly warns against using standard twisted wire brushes under high-speed rotation. This adapter is built specifically for rotating-style chamber brushes, such as Payne Galway-style or coiled chamber brushes, which are designed to safely handle 360-degree motorized cleaning for removing heavy plastic wad and lead fouling.

Will this adapter work with my standard rifle and handgun cleaning brushes?

No, standard rifle and handgun brushes typically use a #8-32 thread size, whereas this shotgun adapter is threaded to #5/16-27. If you need to drive rifle or handgun brushes with your 1/4-inch hex power tools, you will need to look for a separate adapter, such as Borka's #8-32 variant.

Does this mechanical tool require any electrical compliance or SAA/RCM certification in Australia?

No, the Borka Tools ADPT-SHTGN is a passive, unpowered mechanical steel accessory machined from Chromium-Vanadium (CR-V) steel. It contains no electrical components, batteries, or circuitry, meaning it requires no SAA, RCM, or 240V electrical compliance certifications for use in Australia.

Shotgun Choke Adapter - Borka ADPT-SHTGN

The Borka Tools Shotgun Choke/Chamber Brush Adapter (ADPT-SHTGN) converts any standard 1/4" hex drive into a dedicated shotgun cleaning tool. Machined from Chromium-Vanadium (CR-V) steel, this mechanical adapter accepts #5/16-27 female-threaded shotgun accessories, allowing shooters to mount rotating chamber brushes directly to cordless drills, electric screwdrivers, or manual hex handles. It provides a motorized solution for rapidly scrubbing stubborn plastic wad residue, lead fouling, and carbon buildup out of shotgun chambers and removable choke tubes across 12 GA, 16 GA, 20 GA, 28 GA, and .410 GA platforms.

Who is the Borka Tools Shotgun Choke/Chamber Brush Adapter for?

High-volume clay target shooters — provides a motorized cleaning solution that utilizes a standard 1/4" male hex shank to rapidly strip heavy plastic wad fouling and lead deposits from chambers using high-speed drill rotation.
Waterfowl hunters — converts cordless field drills into chamber-cleaning tools via the #5/16-27 female thread interface to clear out carbon, moisture, and debris buildup from removable choke tubes and shotgun chambers.

Less suitable for: Cleaning rifle or handgun bores threaded for #8-32 accessories, which require a dedicated #8-32 hex adapter, or for use with standard twisted wire brushes under high-speed rotation, which require specialized non-directional rotating brushes (such as Payne Galway chamber brushes) or manual non-rotating cleaning rods instead.
