Our range of high-quality grinding wheels for angle grinders and straight grinders offers a wide variety of specifications for various applications and materials.
The Tyrolit range of grinding discs comprehensively covers the most common materials used in metalworking: steel, stainless steel, non-ferrous metals such as aluminium, copper and brass, as well as cast iron. The discs are designed for use with angle grinders and straight grinders and are suitable for rough grinding, surface grinding, edge grinding and the removal of weld seams. The range extends from robust standard discs for everyday use to high-performance ranges such as CERABOND X for particularly hard steel grades or demanding stainless steel applications. Users select the appropriate disc based on the material, machine type and required removal rate – the Tyrolit range offers a tested solution for each of these combinations.
The right disc depends primarily on the material. For Steel discs with a bonding system tailored to steel are used – the colour code on the label is blue. For Stainless steel (INOX) a special bonding system is required to prevent corrosion and pitting; these discs are marked in red and are chemically pure. For Non-ferrous metals For materials such as aluminium, copper, zinc, brass and bronze, discs marked in orange are used, which are designed for these softer materials. Cast iron also requires its own specification – there are discs marked in purple for this purpose. Those who machine both steel and stainless steel can opt for the 2-in-1 variants, which cover both materials without the need to change the disc.
Every Tyrolit grinding wheel bears a standardised specification designation that allows all the tool’s key characteristics to be seen at a glance. Example: A 24 Q-BFX means: A = abrasives (aluminium oxide; alternatively C = silicon carbide, ZA = zirconia corundum, CA = ceramic), 24 = Grit size specification (mesh size; 14–36 = coarse, 46–60 = medium, 80–220 = fine), Q = Hardness designation (N = soft, T = hard), B = Binders (resin-bonded; V = ceramic, E = elastic, G = electroplated), F = Fibre reinforcement using glass fibre fabric, X = Tyrolit internal designation.
In addition, the product label shows the maximum operating speed, the EN safety standards, the OSA safety guidelines, the permissible speed and the expiry date.
The colour code The information on the label immediately indicates the suitability of the material, without having to read the specification code.
A safe grinding wheel is identified by recognised test marks and standards, which are visible on the product label. Tyrolit grinding wheels comply with the applicable EN safety standards and bear the OSA safety symbols (Organisation for the Safety of Abrasives), known worldwide as proof of quality and safety applies to grinding wheels. The label also specifies the maximum working speed in m/s, the maximum permissible rotational speed and the expiry date – all three details must be checked before use. An expired expiry date or exceeding the specified rotational speed jeopardises safety at work. Application and safety pictograms on the label indicate the permissible scope of use. Anyone who is familiar with and checks these markings can safely assess and use grinding wheels from different manufacturers.
The service life of a grinding wheel depends largely on the quality of the abrasive grain and the bond. With conventional discs, the grains detach from the bond in their entirety – the disc becomes blunt quickly and needs to be replaced sooner. Tyrolit CERABOND X roughing discs use a self-sharpening ceramic grain: the grain breaks off in a controlled manner, forming new, sharp edges in the process, so that the cutting performance remains constant throughout the entire service life. The result is significantly longer service life and therefore fewer disc changes per shift. Other factors include: the correct contact pressure (excessive pressure increases wear), working within the specified speed limits, and selecting the correct disc for the specific material. For stainless steel applications, the chemical purity of the PREMIUM stainless steel discs also extends service life, as no corrosion reaction weakens the abrasive grain.
Prolonged exposure to high levels of vibration during grinding can cause musculoskeletal damage, neurological disorders and circulatory problems. Tyrolit addresses this issue with its patented VIBSTAR technology: PREMIUM VIBSTAR roughing discs reduce vibration exposure for the operator and the machine by up to 50% compared with a standard roughing disc. For working situations where noise is the greater concern, these offer PREMIUM SILENTIO roughing discs A 10-decibel reduction in noise levels – equivalent to halving the perceived volume. Both product ranges are equipped with ‘Comfort Start’ technology, which ensures that new discs deliver their full potential from the very first cut, without any jerky start-up. For businesses that must comply with health and safety regulations and actively prevent occupational illnesses, these product lines represent a directly effective measure.
CERABOND X roughing discs combine high-performance ceramic grain with an innovative bonding structure to ensure consistent grinding performance from start to finish. Available for steel, stainless steel and cast iron – also as CERABOND X COMFORT for applications requiring low contact pressure.
PREMIUM VIBSTAR roughing discs reduce vibration loads by up to 50% through patented vibration damping, thereby extending the service life of the machinery.
PREMIUM SILENTIO roughing discs reduce noise levels by 10 decibels, thereby providing long-term protection for users’ health.
Tyrolit has been developing and manufacturing grinding wheels since 1919 and is now one of the world’s leading manufacturers of abrasives. Its range of roughing wheels covers a wide spectrum of materials, machine types and requirements – from standard wheels to patented high-performance solutions. In-house technological developments such as CERABOND X, VIBSTAR and SILENTIO are the result of internal research and are protected by over 500 patents. All Tyrolit grinding wheels comply with the applicable EN safety standards and are OSA-certified. The company is represented in over 140 countries and, in addition to its product range, offers application advice and technical support for metalworking businesses.
