What is the difference between bowl shaped steel wire wheels and disc shaped steel wire wheels

Detailed explanation of the difference between bowl shaped steel wire wheel and disc shaped steel wire wheel

Steel wire wheels can be divided into Dish Brush and Cup Brush types based on their shape and structure, which have significant differences in application scenarios, operating methods, and performance characteristics.

1. Comparison of structural design

Characteristic hole bowl shaped steel wire wheel hole disc shaped steel wire wheel

The shape is bowl shaped, and the steel wire is curved into an arc-shaped disc shape (flat or slightly concave). The steel wire is arranged radially

The density of steel wire is relatively high, the arrangement of steel wire is tight, and the distribution of steel wire is relatively uniform

The center hole design usually has installation holes, which need to be matched with larger flange center holes and can be directly installed to angle grinders or electric drills

The steel wire has a shorter length, stronger rigidity, and longer flexibility

2. Comparison of applicable scenarios

(1) Dish Brush, a bowl shaped steel wire wheel

Suitable for fine processing:

Weld cleaning and deburring

Small area rust removal and polishing

Processing of complex parts such as corners and grooves

Advantages:

Dense steel wire, strong cutting force, suitable for hard materials such as stainless steel and cast iron.

The bowl shaped structure can conform to curved surfaces, reducing the risk of wire jumping.

limitations:

Not suitable for large-scale operations (low efficiency).

The steel wire is short and has poor flexibility, making it unsuitable for soft metals such as aluminum.

(2) Cup Brush steel wire wheel with perforated disc

Suitable for large-scale operations:

Rust removal on the surface of steel plates and large castings

Metal pretreatment (such as cleaning before painting)

Surface roughening of stone and concrete

Advantages:

The steel wire is long, covers a large area, and has high operational efficiency.

Better flexibility, able to adapt to slightly uneven surfaces.

limitations:

The cutting force is weak and not suitable for fine processing.

Steel wires are prone to scattering and require higher protection (such as installing protective covers).

3. Selection suggestions

Recommended types of requirements

Fine polishing, corner treatment, hole bowl shaped steel wire wheel

Large scale rust removal and rapid cleaning of disc-shaped steel wire wheels

Hard metal (stainless steel, cast iron) bowl shaped hole (high cutting force)

Soft metal (aluminum, copper) or curved hole disc type (with good flexibility)

4. Safety precautions

General requirements:

Wear goggles and gloves to prevent steel wire splashing.

Strictly prohibit overspeed use (refer to product calibration RPM).

Regularly check the wear of the steel wire and replace it in a timely manner.

Additional note for hole disc type:

It is recommended to match the protective cover of angle grinder to prevent the steel wire from being thrown out.

summarize

Bowl shaped hole → High precision, strong cutting, suitable for small-scale processing of hard materials.

Perforated disc type → high efficiency, large coverage, suitable for quick cleaning of large surface areas.

Choosing the appropriate type based on specific materials, scope of work, and precision requirements can significantly improve work efficiency and safety!
