Encapsulated Brushes

Brushes with steel wire are also available in encapsulated models.
These Brushes are used for special, but also for common brushing applications.

By embedding in tough plastic the filling width always remains the same and early break of the wires can be prevented. It is the perfect tool for long lasting and safe working.
The abrasion of the encapsulated brush is in small, powdery parts. Hence, working with those brushes is safer, but protective clothing must be worn, though.

The advantages when working with encapsulated brushes are longer lifetime and a harder brush effect.

For different applications different brush types are in use. For example encapsulated end brushes or wheel brushes with shank often are used for the treatment of working parts in the automotive industry.
Encapsulated wheel brushes without shank in different diameters are e.g. used on angle grinders for an effective working on weld seams.

Depending on the application the filling material of the brush is crimped steel wire, stainless steel wire or also brass wire.

For more information concerning the use of encapsulated brushes or also other brushes please contact us or ask for our detailed product catalogue.

Precise working with end brushes with one knot

Among others, Lessmann standard products are e.g. knotted end brushes. Those are ideal for treating bores or slots in components and other working pieces. Next to the common end brushes with several knots, Lessmann also offers end brushes with only one knot.
Especially inner edges and small angles of working pieces can be reached easily with a knot diameter of only 6 mm.

The single knot is twisted against the rotating direction. Thus the knot is not opened while working.

Knotted End Brushes with stainless steel wire
and steel wire 0,15mm

According to the RPM, knotted end brushes with shank will vary in dimension. Therefore it enables the user to work in areas which are hard to reach such as drilled holes, recesses of all kinds or other working parts.
The cups of the knot end brushes with stainless steel wire are coated with plastic to protect the stainless surface. Furthermore they are characterized with a green label to tell them easily apart from brushes with steel wire.

Wires with a diameter of 0,15 mm are less aggressive and more flexible, hence it can adapt even better to surfaces and working parts which need to be treated.

Duster with Polypropylene Filament

Dusters with different filling materials like steel wire, brass wire or coco have been in the Lessmann product range for a long time.
New is the duster with polypropylene filament.

This duster is ideal for dedusting or cleaning. The filling material is relatively stiff, strong and stable to most organic solvents, fats and alcohol as well as to most acids and bases.
The water absorption of polypropylene is very low, that means that the duster is also applicable under wet conditions.
The upper service temperature of polypropylene is 100-110°C.
All those characteristics of the dusters cause a very flexible usage in various industrial companies and crafts enterprises.

This duster measures 320 mm, 175 mm are filled with polypropylene. The filling height is 70 mm.

Cup brushes with straight wire

For finishing large surfaces usually cup brushes are in use. Frequently hand-used machines (e.g. angle grinders) are taken for removing rust, dirt, colour or other adherent particles. Those brushes are in use for a common mechanical deburring, too.

In standard cup brushes the use of abrasive nylon is unusual, because this filling material has special characteristics which can not be applied in common cup brushes.

Abrasive nylon filament for deburring operations in machining centres are approved, therefore Lessmann developed a brush with a straight cup. This tool brings out certain advantages when machining with brushes. Tests show that those advantages can be applied on abrasive nylon as well as on wire filament:
The support of the filling material on the sides in the straight cup causes a higher density with pressure stability. Therefore, when starting the brush on the working piece a higher pressure is produced.
Due to the straight cup the filling material is pressed less to the outside. Hence more cone points work on the surface.
The filling material of brushes with a straight cup is less flexible and advances the brush effects by less immersion depth. A better deburring effect, a higher rate of feed and a longer durability are possible.

Also as a not rotating brush, the cup brush with a straight filament is always advantageous when high pressure in common cup brushes might cause an evasion of the filling material.

Depending on the customers’ demands, cup brushes are available with different threads (M10, M14, W5/8) or bores. Adapter sets and drive arbors are additionally available ex stock.

Weed Brush

This brush is ideal for the removal of moss and weeds in joints and edges on pavements, courtyards or cobbled areas.
Due to the long handle, an ergonomic and effective working is possible. Without stooping, your back is preserved, though it is possible to remove weeds aggressively and precisely.
The brush with set filling material allows a cleaning of edges and joints which are hard to reach.

Filling material (standard): Steel wire, brass coated steel wire. Other filling materials are available on request.

Weed Broom

As well as the weed brush, the weed broom is a brush for outdoors.
Ideally moss and weeds can be removed from terrace boards or cobblestones. An easy and clean working without stooping makes the brush to an effective broom with depth effects. High quality, with brass coated steel wires guarantee a long lifetime of the brush in the well known Lessmann Quality “Made in Germany”.
The body of the weed broom is 140 x 60 mm with 10/9 rows of filling material.

Knotted Brushes for grass trimmers

Knotted brushes on grass trimmers are ideal for removing weeds on grass pavers, curbstones, cobbled areas or other spots which are hard to reach. Those brushes clean larger areas like courtyards, terraces or longer alleys effortless and sustainable.
Additionally, it is environmentally friendly to remove weeds with brushes. Conventional weed-killers often are very aggressive and the use of those can cause groundwater contamination or might harm animals which live in nature. However, brushes are ecologically friendly and they remove weeds fast and effectively.
Working with Lessmann brushes is very effective and timesaving. A high quality of the wire and permanent quality checks guarantee a long durability of the brush and an eminent brushing result.

Lessmann offers in its standard range knotted wheel brushes with a diameter of 175 mm, 200 mm, 250 mm and 300 mm, knotted bevel brushes are available with a diameter of 170 mm and 200 mm. The standard bore is either 20 mm or 25,4 mm, special measurements are available on demand. All brushes are suitable for the common types of grass trimmers.

Removal of wet storage stain with brushes

Zinc coated surfaces are to function as corrosion prevention. But often a humid or wet environment or atmospheric conditions cause this so called wet storage stain. Wet storage stain is a corrosion product of the zinc, which can be removed long-lasting due to a professional treatment.
