Which cutting discs and grinding discs can be used for standard materials such as St37 in metalworking shops?

The standard KSM quality should be used for this work as both a cutting disc and grinding disc for rough work. The flap discs LSZ-FS or LSA-PA in various grain sizes are best used for slurring welding seams and preparing for painting, galvanizing or plastic coating.

Qualities: XT10 XTK10 XT8

What are the advantages of extra-thin cutting discs?

The cutting time can be reduced by up to 50 %
Dust reduction up to 50 %
Little sparking
Low noise
Low machine load, thus longer service life of machine
Low drive output needed
Cutting is possible with weak machines too
Low development of odour
Few combustion residues from the iron such as SO2 and CO2
Lower power consumption
Fewer burrs, thus reduction of the risk of injuries
Lower material losses, very important with stainless steel 
Less reworking 
Narrow cutting joints that can be easily welded during fitting
Sympathetic vibrations in thin steel sheets can be almost excluded

Qualities: << XT 20 >> XTK20 XT8, FT67

General mild steels: Which cutting discs and grinding discs can be used for standard materials such as St37 in metalworking shops?

Universal cutting discs and grinding discs. Flap grinding discs with a brown, normal aluminium-oxide cover

Category: Material

Stainless and acidproof steels: Which discs can be used to process stainless steels?

Use tools that are free from iron and sulphur.  Fe < 0.1%, S < 0.1% KWU Certificate Class II fireproof steels only with TOP quality

Category: Material

Thin metal sheets, pipes, profiles: Which cutting discs can be used to cut thin steel sheets, pipes und profiles with as few burrs as possible?

Extra thin cutting discs are ideal for this work

Category: Material

Non-ferrous metals: Which discs can be used for oily non-ferrous metals?

Only special discs that cannot become clogged. The surface of the flap discs or vulcanized fibre discs must be treated against clogging before grinding. (Spray or grinding paste)

How can I control the surface roughness during surface grinding?

By using flap discs, vulcanized fibre discs, cup discs: they have the advantage of a free choice of grain size.

Category: Bearbeitung

Can I use a single disc for cutting and grinding when grinding root seams?

Yes, combination discs that meet the permissible side load of 290 N are ideal.

Category: Bearbeitung

What disc hardness is recommended for edge grinding?

Hard roughing wheels are best suited for this work. The degree of hardness of the grinding disc is shown by the X number printed on the label.

What are the advantages of extra-thin cutting discs?

Extra-thin cutting discs cut with a very short cutting time, reduced dust development. In addition, fewer sparks and less noise are produced. A lower drive output is possible. This prolongs the service life of the machines and reduces the lateral friction. The reduced material resonances reduce the development of odour. Fewer burrs result in a very narrow cutting joint.
