Rocket Wire Brushes — Twist Knot & Crimped Cup, Conical & Wheel Brushes

Rocket is a wire brush manufacturer producing twist knot and crimped steel wire brushes for angle grinders and bench grinders across the full range of cup, conical, wheel, and hand brush geometries used in metal fabrication, construction, heavy plant maintenance, and surface preparation work throughout Australian industry.

Wire brushing is an essential step in every metalworking and fabrication workflow — weld spatter must be removed before the next pass or before NDT inspection, mill scale must be stripped from structural steel before coating adhesion testing, rust and corrosion must be cleared before welding or repair coating, and primer adhesion surfaces must be clean-profiled before coating application.

The wire brush is the tool that performs all these tasks in the configuration that angle grinders and bench grinders support, and it is consumed at a rate that depends directly on the aggressiveness of the material being cleaned, the duty cycle of the brush, and the speed at which the angle grinder operates.

Twist knot brushes are the high-performance option: the wire bundles are twisted into knots that lock the wires together under centrifugal force during operation, producing a harder and more aggressive wire action against the workpiece surface that removes heavy weld spatter, mill scale, and thick corrosion faster than the more uniform but less aggressive action of a crimped brush of equivalent wire diameter.

Crimped brushes distribute the wire ends more evenly across the contact zone and produce a more uniform scratch pattern across the workpiece surface — preferred for lighter cleaning tasks, blending work, and surface preparation where a consistent scratch profile is required for primer adhesion rather than maximum material removal rate.

AIMS Industrial stocks the Rocket range including twist knot cup brushes in 75mm and 90mm, twist knot conical brushes, twist knot wheel brushes in two widths, crimped cup brushes in 50mm and 100mm, crimped conical brushes in M10 and M14 thread, and steel hand brushes for file cleaning and bench use.

Rocket Twist Knot Wire Brushes for Angle Grinders

Rocket’s twist knot brush range provides the most aggressive wire action available for weld spatter removal, mill scale stripping, and heavy corrosion treatment on steel plate, structural sections, and fabricated weld assemblies.

The twisted wire bundles lock under centrifugal force at operating speed, maintaining consistent aggressive wire projection throughout the brush life rather than the progressive softening and flare that occurs in crimped wire as bristles work loose from the base.

This translates directly into fewer passes per weld joint, faster throughput on surface preparation tasks, and longer productive brush life per unit in high-duty fabrication shops.

• Rocket Twist Knot Cup Brush 90mm x M14: A 90mm twist knot cup brush with M14 thread for use on standard 100mm and 115mm angle grinders for aggressive weld spatter removal, mill scale stripping, and heavy oxide scale removal from steel weld zones and fabricated assemblies. The twist knot wire configuration delivers more aggressive cutting action per pass than a crimped brush of equivalent diameter, reducing the number of passes required to clean a weld bead or strip a corroded surface to a sound metal substrate before coating or re-welding.
• Rocket Twist Knot Cup Brush 75mm x M14: A 75mm twist knot cup brush for smaller angle grinders and for accessing weld zones in tighter spaces where the 90mm cup geometry would contact adjacent surfaces or structure during operation. The reduced diameter allows the cup rim to operate within fillet radii, structural web intersections, and corner weld zones without adjacent surface contact, providing effective weld spatter removal in the congested weld geometries of fabricated structural frames and assemblies.
• Rocket Twist Knot Conical Brush 100mm x M6: A 100mm twist knot conical brush with M6 thread for internal cleaning of pipes, structural hollow sections, tube ends, and bracket openings where a flat cup brush cannot enter the bore or reach the internal surface. The conical profile concentrates the wire action at the working tip for internal scale, weld bead, and corrosion removal inside circular and near-circular apertures inaccessible to any flat-face brush geometry.
• Rocket Steel Twist Knot Wheel Brush M22.2: A twist knot wheel brush for bench grinder and pedestal grinder spindle mounting via M22.2 bore, providing edge cleaning, deburring, and surface preparation on workpiece edges, chamfers, and profiles where cup and conical brush geometries cannot address the edge contact geometry efficiently. The twist knot wheel delivers a more aggressive and faster edge-cleaning action than a crimped wheel brush of equivalent diameter on the same bench grinder application.
• Rocket Steel Twist Knot Wheel 125 x 12mm x M22.2: A 125mm wide-face twist knot wheel brush for larger bench grinders and production wire brushing operations requiring a wider face contact zone across flat workpiece surfaces and structural steel edges. The wider 12mm face width provides a larger sweep width per pass compared to the standard narrow wheel, improving throughput in high-volume wire brushing operations on weldments, structural steel members, and flat plate sections requiring full-face surface treatment.

Rocket Crimped Wire Brushes & Hand Brushes

Rocket’s crimped brush range provides uniform and consistent wire action for lighter scale removal, surface blending, paint stripping, and pre-coating surface preparation where a consistent scratch profile is preferred over maximum material removal rate.

The crimped wire distributes the contact evenly across the entire face width, producing the uniform scratch texture that direct-to-metal primer and high-build coating systems require for reliable adhesion.

The range extends to small-format die grinder cup brushes and hand brushes for detail work and bench tool maintenance — rounding out a complete wire brush offering for Australian fabrication, construction, and maintenance operations.

AIMS Industrial stocks the full Rocket range for direct online ordering, with M14 and M10 threaded variants covering the most common angle grinder spindle standards used in Australian industry — making it straightforward to order the correct brush format for any grinder in the tool store without compatibility uncertainty.

• Rocket Crimped Cup Brush 100mm x M14: A 100mm crimped wire cup brush for light rust removal, surface oxide cleaning, loose paint stripping, and primer adhesion surface preparation on steel. The crimped wire configuration produces a more uniform and even contact pattern across the workpiece surface than twist knot brushes, generating a consistent scratch texture that provides good adhesion profile for primer and coating systems without the deeper and more variable scratch profile of twist knot brushes at the same speed setting.
• Rocket Crimped Cup Brush 50mm x M6: A small 50mm crimped cup brush for die grinders, small angle grinders, and air tools for detailed surface preparation in confined locations, weld zone cleaning in tight corners, bolt hole preparation, and corrosion treatment in recessed locations and behind gussets that larger brushes cannot access. The small 50mm cup size and M6 thread suits the range of die grinders and compact angle grinders used for detailed fabrication work and precision surface cleaning.
• Rocket Crimped Conical Brush 100mm x M14: A 100mm crimped conical brush with M14 thread for internal cleaning of pipe ends, tube bore surfaces, bracket openings, and hollow structural sections where the conical profile directs wire action toward the brush tip for effective internal scale removal and surface preparation. The crimped wire provides a more even action inside circular bores than twist knot wire for applications requiring consistent internal surface texture rather than maximum material removal.
• Rocket Crimped Conical Brush 100mm x M10: The M10 thread variant of the 100mm crimped conical brush for angle grinders fitted with M10 spindles, providing the same internal pipe and hollow section cleaning capability as the M14 variant across the range of smaller angle grinder sizes commonly used in trade workshops and field maintenance where M10 threaded spindles are the standard tool configuration.
• Rocket File Cleaning Hand Brush, Steel: A steel wire hand brush for cleaning loaded files, rasps, grinding wheel faces, and workshop bench surfaces of metal swarf, chips, and embedded material particles that accumulate during machining and filing operations. The stiff steel wire action removes material from file tooth valleys and abrasive wheel surfaces without smearing or pressing embedded particles further into the cutting surface, restoring file and grinding wheel cutting efficiency and extending their service life between dressings.
