Brass-Coated Steel Wire Brush, 18mm Spiral Bristle Design with 1/4" Hex Drive

Brief Overview

This 18mm brass-coated steel wire brush is engineered specifically for removing carbon deposits and burnt residue from the inner sidewalls of cylinders, sockets, and confined passages. The 1/4" hexagonal shank mounts directly into any standard drill chuck or quick coupler, delivering controlled rotational power for efficient cleaning. For shops requiring a broader range of bore sizes, larger 22mm and 25mm brush options are also available to cover different cylinder diameters and applications.

Key Features

• 18mm brush diameter – Optimized for medium-bore cylinder and socket cleaning
• Brass-coated steel wire bristles – Non-ferrous coating resists corrosion and prevents scoring of delicate internal surfaces
• Tightly wound spiral design – Dense bristle clustering provides aggressive yet controlled abrading action
• 1/4" hexagonal drive shank – Universal compatibility with drill chucks, impact drivers, and quick couplers
• Twisted steel core – Reinforced structure maintains bristle integrity under rotational load

Business Advantages for Resellers

• Essential shop consumable – Every engine rebuild and cylinder machine shop requires wire brushes in multiple sizes; stock this 18mm alongside larger diameter options to capture complete job requirements
• High margin item – Low cost, reliable product that moves with every major engine or block service
• Universal drill compatibility – Eliminates customer friction; works with any professional's existing pneumatic or electric tool
• Repeat customer driver – Bristles wear predictably; customers return for replacements regularly

Why This Specification Matters

The 18mm diameter bridges the gap between small precision work and larger cylinder cleaning. Brass coating is critical for this application—it removes carbon without gouging aluminum or cast iron surfaces that contain delicate tolerances. The spiral winding pattern ensures even bristle contact around the full bore circumference, preventing localized scoring that would compromise cylinder wall integrity.

The 1/4" hex drive is the professional standard, ensuring immediate uptake in any shop already running pneumatic or electric drills.
