HARFINGTON 4pcs Bristle Disc 2″ 120 Grit R-Type Abrasive Brush Gray

Description

Product Overview

The HARFINGTON 4‑piece bristle disc set is engineered for professionals who demand precision and durability in abrasive applications. Each disc measures 2 inches (49 mm) in diameter and features a 9.5 mm shank that fits standard 3/8″ drill chucks, allowing seamless integration with a wide range of rotary tools, drills, and small grinders. The discs are constructed from carefully selected emery particles that provide a balanced combination of softness and elasticity, delivering a uniform grinding force across the entire contact surface. With a grit rating of 120, the discs are classified as coarse, making them ideal for rapid material removal, deburring, and coating stripping on metal components.

Key specifications include a maximum rotational speed of 25,000 RPM, a bristle length of 15 mm (0.59 in), and a gray color that resists heat buildup during extended use. The flexible bristles reduce the need for excessive pressure, minimizing the risk of surface scratches while accelerating the cleaning process. The package contains four discs, providing enough inventory for continuous production runs or multiple project setups.

Usage

These bristle discs excel in environments where speed and surface integrity are paramount. In automotive workshops, they efficiently remove paint, rust, and oxidation from engine blocks, chassis components, and brake rotors. Aerospace technicians rely on the discs to clean aircraft structural parts, eliminating contaminants without compromising delicate alloys. In general industrial settings, the discs are used for deburring weld seams, preparing surfaces for welding, and stripping old coatings from machinery housings.

When selecting a tool, ensure the spindle speed does not exceed the recommended 25,000 RPM and adjust the applied pressure to match the material hardness. For softer metals, a lower speed and lighter pressure will prevent bristle breakage, while harder alloys may benefit from a slightly higher speed to maintain effective material removal. Always wear appropriate personal protective equipment, including safety glasses and hearing protection, as the high‑speed operation can generate fine particulate debris.

FAQ

Can these discs be used on non‑metal surfaces?

While the discs are optimized for metal, they can safely clean hard plastics and composite materials when operated at lower speeds and with reduced pressure.

What is the recommended maximum pressure during use?

Apply light to moderate pressure—typically no more than 2 kg of force—to avoid bristle breakage and ensure even material removal.

Are the discs compatible with all 3/8″ drill chucks?

Yes, the 9.5 mm shank is standard for 3/8″ chucks, making the discs compatible with most cordless drills, rotary tools, and bench grinders.

How often should the discs be replaced?

Replacement frequency depends on usage intensity; for heavy industrial work, expect a lifespan of 8‑10 hours of continuous operation before performance diminishes.

Do you offer bulk pricing for larger orders?
