4-Inch 100mm Shaft Circular Brush, 6mm Arbor, Crimped Steel Wire

Brief Overview

This 4-inch circular shaft brush is a workhorse for rust removal, paint stripping, corrosion cleaning, and general surface preparation in automotive, maintenance, and industrial shops. The densely crimped steel wire bristles are mounted on a rigid metal backing plate with a 6mm arbor shaft for direct installation into any standard drill chuck or rotary tool. For operators working across multiple applications, pairing this brush with smaller diameter circular brushes or specialty cup-style alternatives extends your shop's surface-prep capabilities across different geometries and confined spaces.

Key Features

• 4-inch (100mm) brush diameter – Covers large flat surfaces efficiently
• Crimped steel wire construction – Superior durability and aggression compared to softer wire grades
• 6mm shaft (arbor) – Standard size for universal drill chuck compatibility
• Maximum rated speed: 4500 RPM – Safety rating clearly marked on the backing plate
• Rigid metal backing plate – Prevents wire bristle spreading under load

Why Resellers Choose This Brush

This is a high-turnover product for professional maintenance shops. Every technician rotating through rust removal, brake dust cleaning, or paint-prep work generates repeat orders. Unlike disposable wire wheels that shed bristles, the stamped backing plate and crimped wire design provide extended service life, reducing per-job costs. Stock this 4-inch size alongside smaller alternatives to capture the full range of restoration and maintenance projects your customers handle.

Why This Size Matters

At 4 inches, this brush strikes the practical balance between coverage and control. It's large enough to clear broad surface areas quickly (engine blocks, frame components, structural steel), yet compact enough to maneuver in moderately confined spaces. The crimp construction ensures bristles maintain their bite throughout the bristle life, making it a reliable choice for heavy corrosion and stubborn paint.

Reseller Value Proposition

• Fast inventory turnover – High demand in automotive service, maintenance, and restoration sectors
• Competitive margin potential – Consumable wear pattern ensures repeat orders
• Cross-sell opportunities – Complement with smaller diameters and multi-piece brush assortments to maximize cart value
• Minimal technical support – Straightforward product with clear safety ratings and mounting instructions

Stock this brush as a core rotation tool for any shop serious about surface preparation work.
