Diamond cutting discs:         

Our diamond cutting discs are suitable for different materials. Our wide range ensures that you will find the right disc for your material.

Fast and cutting through natural stone and granite. Our diamond cutting disc Turbo, Art. 50260, is particularly narrow at 1.2 mm. This allows you to cut your material extra fast and precisely.

Work on tiles and porcelain stoneware with our SPEED cut-off wheel, Art. 50250. Because this wheel is not only fast and super-thin. It also has a flange-reinforced steel core.

Are you facing hard granite or concrete? Our red-point cut-off wheel, Art. 50293, is suitable for this, because the special segments turn red and give you an early warning of overheating.

Metal and stainless steel are best processed with our Allrounder grinding disc, Art. 50048. Due to the short-tooth vacuum coating, this disc works through metal and stainless steel without any problems. The special processing ensures less sparking and odor formation.


All diamond cutting discs have - if not marked otherwise - a bore of 22.24 mm. Thus, they fit on any commercially available:

Diamond drill bits

From Ø 6 mm to Ø 100 mm we offer all drill bits. In gold, with kerosene cooling, as a set or individually. Convince yourself today of the consistently excellent quality and variety of our diamond tools.

Our gold drill bits are particularly popular. They are suitable for porcelain stoneware, marble and granite up to a material thickness of 35 mm. We also offer the most common sizes as a set.

A really practical tool for our diamond tool is our stainless steel drilling jig. With it, you drill pinpoint holes in walls and floors. The tapping jig is self-priming and therefore holds on all smooth, flat surfaces.

Diamond burrs

Put the finishing touches on tiles, porcelain stoneware, mosaics or natural stone. Due to the fine shapes of the diamond profile pins, you can work even the smallest corners without any problems. Due to the different shapes of the burrs, all kinds of repairs as well as small fine and milling work are possible.

The diamond burrs fit perfectly into the chuck of your drill or cordless screwdriver.

Try our profile pins in the practical set, Art. 50343. Here you get 5 different profile pins for your individual work.


Diamond joint cutter

Wherever round diamond cutting discs cannot reach, our diamond joint cutters show their advantages. For example, even narrow joints can be removed cleanly without damaging the tile edges. Work on edge and corner areas is also possible. This is very helpful, for example, when renovating joints in the sanitary area.

In addition, the grout cutters are characterized by the oscillating movement of the multi-function device. This creates significantly less dust than when working with cut-off wheels, for example.

Diamond grinding pots

Only our diamond cup wheels are more stubborn than adhesive residues! With Ø 100 mm and M14 thread, the cup wheel is quickly mounted on your angle grinder and the work can start.

The cup wheel is suitable for both coarse and fine grinding work on concrete and screeds. Whether dry or wet use: The cup wheel works extremely fast and clean without fraying the edges.   


Diamond Hand Pads

Use our 90 x 55 mm diamond hand pads for hand grinding and polishing granite, marble, terrazzo and ceramics. Whether dry or wet application, the hand pads convince with a high removal rate.

With the different grit sizes you get different fine results. The higher the grit, the finer the result.
