KS TOOLS BT103110 poraharjalisäosa sarja, 4-osainen, kuusiokanta, nylonharjakset

For cleaning grout, wheels, or workbench surfaces, this four-piece brush set mounts directly into a standard drill chuck. The hexagonal shank prevents slipping in the chuck, and the nylon bristles are stiff enough for scrubbing without scratching painted or plated surfaces. Each brush has a different shape to reach flat areas, corners, and curved recesses.

Key specifications

• Number of pieces: 4
• Shank type: Hexagonal
• Shank size: 1/4 inch (6.35 mm)
• Bristle material: Nylon
• Brush shapes: flat (100 mm), flat (80 mm), conical (80 mm), round (50 mm)
• Compatibility: drills, cordless drills, impact drivers

Why choose it

The set covers the most common cleaning tasks: the large flat brush clears wide surfaces, the smaller flat brush fits tighter spots, the conical brush reaches into corners and crevices, and the round brush works inside cups or around bolts. Because the shank is hexagonal, the brushes stay secure even under load.

Ideal use cases

• Removing rust and oxidation from metal parts
• Scrubbing tile grout and bathroom fixtures
• Cleaning automotive wheels, engine bays, and undercarriages
• Preparing surfaces for paint or adhesive

Good to know

The nylon bristles are colour-coded yellow for quick identification. The plastic base is durable and resists common cleaning chemicals. Use with a variable-speed drill and moderate pressure for best results.
