Filling Materials

Steel Wire (STA)
straight / crimped

Steel Wire is developed in co-operation with wire producers, so that it meets our special requirements. This wire is alloyed with manganese in order to increase its toughness. Result is higher tensile strength and longer lifetime of LESSMANN Brushes.

Steel Wire High Tensile (STH)
straight / crimped

Steel wire high tensile is most often used in Knotted Brushes, Deburring Brushes and Pipeline Brushes. Furthermore we offer this high tensile wire in our complete assortment. Above all it features through its tensile  strength  and  high  fatigue  rates,  what  results  in  lifetime  even  for  extreme  brushing applications.

Brass Coated Steel Wire (STM)
straight / crimped

For long lifetime plus high tensile strength and cutting performance. Best results in brushing and deburring applications.

Cord Wire (STL)

Brass coated steel wire corded. Longest lifetime for heavy duty brush applications e. g. deburring.

Stainless Steel Wire (ROF/ RO4 / RO8 / ROL)

ROF:   must be used when working on stainless steel. Material number (WNr.) 1.430 (AISI 304). This wire is resistant against corrosion and certain acids and bleaches.  

RO4:  Premium-quality stainless steel wire. WNr. 1.4401 (AISI 316).

RO8:  High heat resistant stainless steel wire. WNr. 1.4860.

ROL: Stainless Steel Wire with cord construction WNr. 1.4310.

Stainless Steel Wire High Tensile (ROH)

This wire is characterized by a high tensile strength and a long lifetime even in extreme applications. WNr. 1.4310 (AISI 301).

Brass Wire (MES)
CuZn

Brass Wire is softer than steel wire. Among other applications brass wire is suitable for working with mild bleaches. It’s mainly used for processing of nonferrous metals.

Bronze Wire (BRO)
CuSn6

Bronze Wire is used for surface processing of wood and metal. It’s also used when non sparkling brushes are needed.

Nickel Silver (NSI)
CuNi

Nickel Silver is used for polishing work pieces e. g. parts of nickel silver or brass, as it is softer than steel wire.

Synthetic Filaments PP, PA, PE

Synthetic Filaments are resistant to abrasion and flexible. Despite minor resistance against heat these  filaments are perfect for cleaning, grinding or surface processing of  metal, plastic or wood. 

Available are:

• Polypropylene (PP)
• Polyamide (PA) - PA 6, PA 6.6, PA 6.12
• Polyethylene (PE)

Fibre (FIB)

Fibre consists of heat resistant plant fibre, is slightly abrasive and therefore can be used for smooth grinding, above all for working on wooden surfaces. Moreover fibre is used for general cleaning and polishing work.

Horse Hair (ROS)

Horse Hair is an animal hair, which above all is deployed in terms of light cleaning and dusting work. Horse hair is resistant against diluted acids and bleaches. It’s not chargeable for static electricity.

Encapsulated Brushes

Encapsulated brushes are ideal for an aggressive work on working pieces and for a very exact working in edges and angles. By embedding steel wire, stainless steel wire, brass coated wire or brass wire in tough plastic, the filling width always remains the same and early break of the wires can be prevented. It’s the perfect tool for long lasting and safe working. The advantages when working with encapsulated brushes are longer lifetime and harder brush effect.

Furthermore the risk of injury declines when using encapsulated brushes.

Abrasive Filaments (SIC/AO)

Abrasive Filaments consist of polyamide bristles containing abrasive grits. This modern material is ideal for deburring work, fine surface finishing of plastic and metal parts as well as grinding, cleaning, polishing and structuring surfaces. With their flexible surface, brushes with abrasive filament  align to the different shape of working pieces. Abrasive bristles also have grinding effects on the side, which makes them even more flexible to application possibilities. You can choose between grit (from K60 to K1000) composed of aluminium oxide (AO) and silicon carbide (SIC).

Also diamond grit is available.
