Koch-Chemie Drill Brush Set Medium — Drill Attachment Cleaning Brushes

Medium-Firm Drill Attachment Cleaning Brush Set

Koch-Chemie Drill Brush Set Medium is a 3-piece power-assisted scrubbing brush set equipped with standard 1/4-inch quick-change hex shanks for cordless drills and drivers. Crafted with durable medium-density nylon bristles, it powers through deeply embedded dirt, mud, sand, and beverage spills in vehicle carpets, boot liners, heavy upholstery, and rubber foot mats with minimal manual effort.

Key Performance Advantages

• 3 Task-Specific Brush Geometries: Includes a flat 10 cm disc for broad carpet surfaces, a compact 5 cm detail disc for tight footwells, and a rounded bullet brush for curved corners and contours.
• Medium-Firm Calibrated Nylon: Provides intensive scrubbing agitation without fraying automotive fabric weaves or damaging pile fibers.
• Universal 1/4" Hex Shank: Fits securely into standard cordless drill chucks and quick-change magnetic holders.
• Chemical Resistance: Bristles and polymer backing resist alkaline interior cleaners (Pol Star, Mehrzweckreiniger) and extraction detergents.

Recommended Usage Guidelines

1. Spray vehicle fabric cleaner (e.g. Pol Star diluted 1:10–1:20) generously over the soiled area.
2. Insert the desired brush into a cordless drill and run at low to moderate speeds without excessive downward force.
3. Let the rotating bristles agitate the foam and lift the embedded grime.
4. Extract the suspended dirt using a wet vacuum or wipe thoroughly with a damp microfiber cloth.
