SIT Wire, Cup & Wheel Brushes — Quick Reference
SIT = industrial wire brush range — crimped and twist-knot wire wheels, cup brushes, hand brushes and specialty tube brushes in steel, stainless steel and brass, for weld prep, rust removal and surface cleaning.
| SIT Brush Type | Material | Best For |
|---|---|---|
| Cup Brushes (crimped & twist-knot) | Steel / stainless / brass | Angle grinder surface prep, rust & scale removal |
| Wire Wheels (crimped & twist-knot conical) | Steel / stainless / brass | Bench grinder cleaning, weld prep, deburring |
| Hand & Slim Brushes | Steel / stainless / brass / nylon | Manual cleaning, tight-access work, welders' brush |
| Boiler & Condenser Tube Brushes | Steel / brass | Internal tube & heat exchanger cleaning |
Material choice matters: steel wire is the aggressive, general-purpose choice; stainless steel wire avoids contaminating stainless workpieces with carbon steel particles (which can cause surface rust staining); brass is softer again, for cleaning without scratching softer metals. Brand: SIT. Companion: wire brushes, abrasives, power brushes, hand brushes, spiral tube brushes.
SIT Industrial Brushes for Australian Trade & Workshop Use
SIT is an industrial wire brush range supplied through AIMS Industrial covering the full spread of surface preparation and cleaning brushes a fabrication shop, maintenance team or trade workshop needs: cup brushes and wire wheels for power tool use, hand and slim brushes for manual work, and specialty tube brushes for boiler and condenser cleaning.
Cup brushes and wire wheels for power tools
SIT's crimped and twist-knot cup brushes and wire wheels are sized for angle grinders and bench grinders, in steel, stainless steel and brass across a wide range of diameters and arbor sizes. Crimped wire gives a softer, more flexible action suited to general cleaning; twist-knot construction holds its shape under load and cuts more aggressively, which suits heavier rust, scale and paint removal and weld prep between passes.
Hand brushes and welders' brushes
Slim hand brushes and traditional wooden-handled welders' brushes cover the manual cleaning work that doesn't need a power tool — knocking slag off a weld, cleaning up a tight corner, or general workshop cleaning. SIT's slim brush range comes in steel, stainless and nylon fill depending on how aggressive the cleaning action needs to be.
Boiler and condenser tube brushes
A more specialised part of the range: flexible-extension boiler tube brushes and condenser tube brushes in steel and brass, sized to clean the internal surfaces of tubes and heat exchangers where a standard brush can't reach.
Choosing the right material
Steel wire is the default aggressive, general-purpose choice for mild steel work. Stainless steel wire brushes exist specifically to avoid cross-contaminating stainless steel workpieces — using a carbon steel brush on stainless can embed steel particles that later rust and stain the surface. Brass is softer than both, used where the workpiece itself is softer or where a less aggressive cleaning action is needed.

People Also Ask — SIT
Q: What's the difference between a crimped and a twist-knot wire brush?
Crimped wire gives a softer, more flexible brushing action suited to general surface cleaning, while twist-knot construction holds its shape under load and cuts more aggressively — better suited to heavier rust, scale and paint removal, and weld prep between passes.
Q: Why use a stainless steel wire brush instead of a standard steel one?
A stainless steel wire brush avoids cross-contaminating a stainless steel workpiece with carbon steel particles. Those particles can embed in the surface and later rust, leaving stains on metal that's meant to stay corrosion-resistant.
Q: What's the difference between a cup brush and a wheel brush?
A cup brush has a cup-shaped bristle face for cleaning flat surfaces, corners and welds with a power tool held at an angle to the work. A wire wheel has a flat, radial bristle face, typically used on a bench grinder for cleaning parts brought to the wheel, or on an angle grinder for edges and detail work.
Q: Are SIT brushes suitable for angle grinders?
Yes — SIT's cup brushes and wire wheels come in arbor sizes matched to standard angle grinders and bench grinders, in steel, stainless steel and brass depending on the surface and level of aggression needed.
Q: What's a boiler or condenser tube brush used for?
It's a specialty brush, often on a flexible extension, sized to clean the internal surfaces of boiler tubes, condenser tubes and heat exchangers — a job a standard external wire brush can't reach.
