Crimped brass wire cup brush 4 inch

4-Inch Crimped Brass Wire Cup Brush.

The -Inch Crimped Brass Wire Cup Brush is a professional-grade surface preparation tool. It is designed for cleaning, stripping, and finishing metal surfaces without the risk of sparking or damaging the base material.

This Crimped brass wire cup brush 4 inch features crimped brass-coated wire bristles. These provide aggressive yet non-marring cleaning action. It is the preferred choice for automotive restoration, marine maintenance, and non-ferrous metal fabrication.

The Crimped brass wire cup brush 4 inch is engineered for use with standard angle grinders equipped with a 5/8″-11 threaded arbor. It delivers reliable performance at a maximum operating speed of 8,500 RPM.

Unlike steel wire brushes, the brass construction is non-sparking. This makes it safer for use in environments where flammable vapors or combustible dust may be present.

The Crimped brass wire cup brush 4 inch design creates a flexible, fast-cutting brush face. Crimped brass wire cup brush 4 inch conforms to flat surfaces, contours, and irregular profiles.

Crimped brass wire cup brush 4 inch effectively removes rust, oxidation, paint, and weld spatter without excessive gouging or surface degradation. It delivers the perfect balance of durability, control, and surface-safe cleaning power.

What is a Crimped Wire Cup Brush and How Does It Work?

A Crimped brass wire cup brush 4 inch is characterized by wave-shaped individual wire filaments. These are mechanically locked into a steel cup-shaped hub.

Unlike knotted wire brushes, the Crimped brass wire cup brush 4 inch  design creates thousands of individual cutting tips. This provides a smoother, more consistent surface finish.

The Crimped brass wire cup brush 4 inch shape concentrates the cleaning action at the wire ends. This allows the brush to efficiently clean flat panels, weld beads, and contoured components.

When mounted on a compatible angle grinder, the brush rotates at high speed. The flexible crimped wires wipe across the surface, lifting contaminants while leaving the underlying metal intact.

What Are the Verified Technical Specifications?

The Crimped brass wire cup brush 4 inch diameter is 4 inches. This provides optimal coverage for medium-to-large surface areas while maintaining maneuverability in tight spaces.

The mounting type is a 5/8″-11 threaded arbor. This is the standard US pattern for angle grinders. It fits most DeWalt, Makita, Milwaukee, and Bosch grinders.

The maximum RPM is 8,500. Exceeding this speed rating may cause wire fracture and hazardous debris ejection.

The wire material is brass-coated steel or solid brass alloy. This provides non-sparking, non-marring performance suitable for aluminum, copper, brass, and stainless steel.

The trim length is 1-3/16 inches. This is the working length of the bristles. Longer trim provides increased flexibility.

The wire diameter is 0.3 inches. This is heavy-gauge wire for aggressive cleaning without excessive base material removal.

What Are the Ideal Applications for This Brush?

This Crimped brass wire cup brush 4 inch is specifically engineered for light-to-medium duty surface preparation tasks. Preserving the integrity of the base material is critical.

In automotive restoration, it cleans aluminum intake manifolds and cylinder heads without gouging sealing surfaces. In marine maintenance, it removes oxidation from bronze propellers and brass fittings.

In woodworking, it cleans resin and pitch from saw blades without damaging cutting edges. For electrical work, it provides non-ferrous, non-sparking brushing near live circuits.

In antique restoration, it gently removes surface rust from vintage tools without eroding original markings.

Is This Brush Compatible with My Grinder?

This Crimped brass wire cup brush 4 inch uses a 5/8″-11 threaded arbor. This is the standard mounting specification for nearly all professional and consumer angle grinders sold in North America.

If you are using a grinder with a different spindle thread, this brush will NOT be directly compatible. For metric-spindle grinders, you will require an adapter or a brush specifically manufactured with M14 threading.

Always verify your grinder’s spindle specifications before ordering.

What Are the Critical Safety and Usage Considerations?

Never operate this brush above 8,500 RPM. Exceeding the maximum rated speed can cause wire bristles to fracture and eject at high velocity.

Always wear ANSI Z87.1-rated safety glasses, a full face shield, heavy-duty work gloves, and hearing protection.

New crimped wire brushes may shed some loose bristles during initial use. Run the brush at reduced speed for 30-60 seconds before applying to the workpiece.

Do not force the brush. Allow the wire tips to do the work. Excessive pressure causes premature bristle fatigue, reduced brush life, and poor surface finish.

What Is NOT Included or Specified?

The product listing does not specify whether the bristles are solid brass or brass-coated steel. This distinction is critical for applications requiring absolute non-sparking performance or chemical compatibility.

If your application requires verification of solid brass construction, contact Titan Tools directly or select an alternative certified product.
