Coated abrasives
Grinding with coated abrasives has significant advantages over the use of other grinding products and has increasingly penetrated areas which in the past have been reserved only for rigid grinding tools:
- cost-efficiency - shorter time and lower costs of manufacture,
- simple and safe to use - no special skills needed,
- reduced vibration during grinding,
- uniformly ground surfaces.

Flap discs
Flap discs are intended for use with manual grinding machines at a maximum peripheral speed of 80 m/s. They are distinguished by high durability, lower noise levels, smoother operation, simple use and high grinding efficiency.
They are used for basic grinding, fine grinding of welds, polishing, finish machining of edges, surface machining and cleaning of alloys.
A class discs (with abrasive fabric containing aluminium oxide grit) are intended for machining aluminium, softer alloys, low-alloy steels, plastics and wood.
Z class discs (with abrasive fabric containing zirconium and aluminium oxide grit) are intended for machining alloys, tough non-ferrous metals, high-alloy and temperature resistant and thermally hardened steels.
Three quality levels are available:
- ECONOM for nonprofessional tasks,
- STANDARD for general applications in industry and in home workshops,
- TOP for professional jobs.

Grinding wheels and grinding wheels with shaft
Grinding wheels
Grinding wheels are intended for manual and machine grinding.
A class grinding wheels enable the grinding of all types of low alloy steels, colour metals, alloys, wood and plastics.
Z class high-quality grinding wheels enable the grinding of high alloy steels, tough colour metals, heat resistant, stainless and thermally hardened steels.

Grinding wheels with shaft
Grinding wheels with shaft are intended for grinding using linear manual grinding machines.
A class grinding wheels with shaft enable the grinding of all types of low alloy steels, non-ferrous metals, alloys, wood and plastics.
Z class high-quality grinding wheels with shaft enable the grinding of high alloy steels, tough non-ferrous metals, heat resistant, stainless and thermally hardened steels with linear manual grinding machines.

Rolls of abrasives
Rolls of abrasives for manual grinding are used primarily for grinding painted and varnished surfaces, wood, non-ferrous metals, alloys and steel.
Abrasive rolls (PDF 0,2 MB)
Sheets of abrasives
Sheets of abrasives for manual grinding and grinding with manual grinding machines are intended for grinding painted and varnished surfaces, wood, non-ferrous metals, alloys and steel.

Vitrified bonded grinding tools
Vitrified bonded grinding tools are distinguished by their resistance to chemical influences and storage time. They hold shape very well and are useful in all types of grinding (from very coarse to the finest grinding). Large abrasive grit is intended for coarse grinding in which large material removal rates are required, while fine grit is used to achieve smooth surfaces and small material removal rates.
The hardness range of vitrified bonded grinding tools is very wide. A general rule for determining grinding tool hardness states that softer grinding tools should be used for grinding harder materials and vice versa.
Applications:
- ironworks,
- foundries,
- shipbuilding,
- machine construction,
- automotive industry,
- tool making,
- construction,
- agriculture,
- food industry,
- glass making,
- stone cutting,
- arts and crafts.

Diamond and CBN product range
Compared to standard abrasives, grinding tools with superabrasive powders (diamond and CBN powders) are distinguished by greater hardness, better temperature conductivity and less wear.
The proportion of use of grinding tools with superabrasive powders is increasing due to the increasing use of difficult-to-machine materials, as well as greater requirements for dimensional accuracy and the quality of machined surfaces.
COMET's grinding tools contain superabrasive powders of the most reputable world manufacturers.
Grinding tools with diamond and CBN powders are useful in many machining applications. However, correct selection of the grinding tool is very important, because it affects both the effectiveness and cost-efficiency of grinding.

Magnesite and synthetic grinding tools
Magnesite and synthetic bonded grinding tools are intended for the machining of granite, marble, concrete, terrazzo, ceramics and artificial stone.
They should be stored in a dry area at a temperature of between 5 and 25° C and at a relative humidity between 40 and 60 %.
In magnesite bonded grinding tools it is necessary to observe the shelf life, which is typically one month or at most one year from the date of manufacture, while synthetic grinding tools have an unlimited shelf life.

Dressing tools with diamond grit
Dressing tools are intended for the dressing and profiling of grinding tools. Vitrified bonded grinding tools need to be restored i.e. dressed once the sharp edges of the tool's cutting surface become worn out: the normal force FN increases and the grinding tool becomes louder and no longer cuts.
For the dressing of grinding wheels COMET produces various dressing tools for both manual and machine dressing.
