Choose the right tool depending on the material being processed
Weld seam processing
Stripping and levelling welds on steel and stainless steel. Grit size P40-P60 for rough finishing.
Paint and rust removal
Effective removal of old coatings, paint, varnish and corrosion. P60-P80 for optimal performance.
Surface preparation
Surface sanding before painting, welding or coating. P80-P120 for finishing.
Deburring and deburring
Deburring after cutting, punching and drilling metal. P40-P60 for fast removal.
Stainless steel (INOX)

FAQ
Frequently asked questions
Answers to the most common questions about flap discs
What is the difference between T27 and T29?
T27 (Type 27) is a flat flap disc for use at an angle of 0-15 degrees to the surface. T29 (Type 29) is a tapered disc for use at an angle of 15-25 degrees. T29 provides more aggressive material removal and better surface contact when grinding at an angle.
Which abrasive is better: zirconia, ceramic or aluminum oxide?
Ceramic (CR) -- the most productive abrasive for heavy-duty work on stainless steel and alloy steels. Zirconia (ZR) -- a versatile choice with high resistance for steel and stainless steels. Aluminum Oxide (AL) -- an economical option for general grinding of mild and medium steels.
What grain size should I choose for my task?
P36-P40 -- rough sanding, heavy material removal, weld grinding. P60 -- general purpose grit for most jobs. P80 -- semi-finishing, surface preparation. P100-P120 -- finishing, preparation before painting.
Can I use a flap disc instead of a grinding disc?
Thus, flap discs often replace type 27 grinding discs. They operate more quietly, with less vibration, provide better surface quality and do not require a backing pad. At the same time, they remove material efficiently.
What is the maximum rotation speed?
The maximum speed is marked on each disc. For 125 mm discs this is usually 12,200 rpm (80 m/s), for 115 mm discs it is 13,300 rpm. Never exceed the speed indicated on the disc marking.
Are flap discs suitable for stainless steel?
Yes, zirconium (ZR) and ceramic (CR) abrasive discs are excellent for stainless steel. They do not overheat the surface or leave contaminants that can cause corrosion.
How long do flap discs last?
The shelf life of flap discs is 3 years from the date of manufacture. Store in a dry place, avoid direct sunlight and contact with moisture.
How to work with a flap disc correctly?
Hold the grinder at an angle of 15-25 degrees to the surface (for T29) or 0-15 degrees (for T27). Do not press too hard - let the abrasive do its work. Move evenly, without stopping in one place. Always use a protective cover and goggles.
