Selection of internal brushes: wire, microabrasive, plastic-bonded
Wire, microabrasive and internal brushes on a plastic bond are ideal for a wide range of tasks: from removing scale and burrs to grinding, polishing, rounding off edges and finishing surfaces. They are used for smoothing and structuring various materials.
These tools are especially in demand in the automotive industry, handicraft and metallurgical industries, the oil industry, and in pipeline construction. The brushes work effectively with materials such as aluminum, stainless steel, plastic, wood, copper, titanium, zinc and hard non-ferrous metals
Lessmann, one of the leading European manufacturers of technical brushes, offers a wide range of internal brushes designed for processing hard-to-reach areas: holes, pipes, channels and internal threads.
Advantages of Lessmann brushes:
- german quality and durability
- wide range of sizes
- reliability under intensive use
Depending on the task, two main types are available: internal wire and microabrasive internal brushes.
Internal wire brushes
Intended for:
- removing burrs, scale, rust
- preparing the surface for welding or painting
- cleaning internal threads and holes
- removing scale
Features:
- available with different wire stiffness: steel, brass, stainless steel
- diameter: from very thin (for precision work) to larger
- possibility of mounting in a hand tool or on a drill/machine
Advantages:
- brushes can be used both manually and mechanically.
Microabrasive internal brushes
Intended for:
- fine grinding
- polishing internal surfaces
- finishing without damaging the workpiece
- deburring holes or grooves
Features:
- equipped with abrasives distributed over a synthetic thread
- ensure uniform processing without the risk of scratches
- used for non-ferrous metals, aluminum, plastics and soft alloys
Advantages:
- abrasive bristles made of aluminum oxide or silicon carbide make them more flexible than conventional internal brushes.
- the flexible thread allows internal brushes to adapt to the contours of the workpiece bore, allowing cleaning of hard-to-reach areas.
- Lessman also supplies diamond-coated brushes, which are used for very hard materials.
Lessmann internal brushes are a reliable tool for high-quality processing of the most difficult to reach places with a guarantee of results!
