Tyrolit tungsten carbide burrs are manufactured from tried-and-tested, high-quality tungsten carbide using state-of-the-art CNC grinding machines. As a result, our extensive assortment can be used on hand-guided, pneumatic and electric machines, as well as on industrial robots, and is suitable for machining a variety of materials such as steel, stainless steel, aluminium and cast iron.
Tyrolit tungsten carbide burrs are made from tried-and-tested, high-quality tungsten carbide and are manufactured on state-of-the-art CNC grinding machines. The result is an efficient precision tool that delivers both maximum standing time and aggressive material removal — even in hard-to-reach areas. The assortment covers a wide spectrum of materials: from various grades of steel and stainless steel, through aluminium and nonferrous metals such as copper, bronze and brass, right through to cast iron and HSS, numerous materials can be machined reliably. A specially developed cutting edge geometry consistently ensures reduced generation of heat — this protects both the tool and the workpiece and reliably prevents surface tarnishing when machining stainless steel. The components of the tungsten carbide burrs are soldered; a copper alloy between the head and the point gives the tool a certain degree of impact tolerance, which increases safety during use and enhances performance.
The right choice depends on the material. Tyrolit offers material-specific ranges of tungsten carbide burrs, each tailored to the cutting behaviour, generation of heat and chip transport of the respective material.
A dedicated product range is available for steel, designed for demanding applications on various steel grades — with a cutting edge geometry that delivers high material removal rates whilst minimising heat build-up. Stainless steel is particularly susceptible to discolouration caused by heat: the corresponding stainless steel range consistently keeps heat build-up to a minimum, reliably preventing surface tarnishing. For aluminium and nonferrous metals — including aluminium bronze, aluminium base alloys, copper, bronze, brass, nickel silver and titanium — a dedicated range is available with cutting edge geometries tailored to these materials, which effectively prevent the soft material from sticking to the cutting edge. The range for cast iron, steel and stainless steel covers the widest range of materials: it is suitable for universal grinding tasks on high alloyed steels, rust-, acid- and thermal-resistant castings, as well as cast steel and welding seams, and is available in several cutting edge geometries — including a chip-breaker and a fine-diamond variant. Those requiring the highest power class should opt for the PREMIUM HPC (High Performance Coating) tungsten carbide burrs, which achieve up to twice the material removal rate on cast iron, steel and stainless steel compared to other premium tungsten carbide burrs.
Tyrolit tungsten carbide burrs are available in more than 15 different profiles, designed for varying levels of accessibility, geometries and machining tasks. The cylindrical round shape (52WRC) is the most versatile and is suitable for flat surfaces, welding seams and general removal work. Cylindrical designs (52ZYA) are used wherever straight walls or flat surfaces are required — the version with face teeth (52ZYA-S) also allows for planar penetration. Ball cutters (52KUD) enable the machining of internal radii and convex faces. For conical transitions and hard-to-reach angular areas, round cones (52KEL), pointed cones (52SKM) and the angle milling cutter variants (52WKN, 52KUD-N) are available. Special shapes such as deseaming (52FLH), teardrop (52TRE) and bullet (52SPG) are designed for machining roundings, shaped surfaces and chamfers. The groove milling cutter shape (52RND) enables the machining and rework of flutes. In addition to the workpiece geometry, accessibility to the machining area is also a decisive factor in selecting the shape: the more restricted the access, the more compact the cutter profile should be.
The head diameter is the most important selection criterion, as it directly influences material removal and accessibility. In the Tyrolit assortment, it ranges from 3 mm for precision work in confined geometries to 25 mm for large-area material removal. Depending on the design, the shaft diameter is 3 mm (consumables and miniature shapes), 6 mm (standard for straight grinders) or 8 mm (larger milling heads from approx. 12–16 mm head diameter). Overall lengths vary from 38 mm for consumables to 78 mm for larger designs. Dimensions are specified in the format: head diameter × cutting length – shank × overall length, for example 10 × 19 – 6 × 65. Sets contain the most common shapes and dimensions combined in a single kit — practical for initial set-up or for specialist retailers.
Tyrolit tungsten carbide burrs are designed for use on hand-guided pneumatic and electric machines as well as on industrial robots. In the hand-guided sector, the straight grinder is the typical machine — it enables precise work even in hard-to-reach places and is used in the metal industry for deburring, smoothing and shaping work. Pneumatic variants are particularly suitable for high-performance straight grinders and the associated more intensive use in mass production. The shaft diameter is crucial for machine compatibility: 6 mm is the standard for hand-guided straight grinders, whilst 8 mm is used for larger designs and stationary or robot-assisted applications. For automated use on industrial robots, the cutters are sufficiently impact-resistant even under higher process forces, thanks to their brazed construction using a copper alloy. Those performing machining on composite materials such as glass fibre or carbon fibre will find the optimised assortment on the composites industry page.
The PREMIUM HPC (High Performance Coating) tungsten carbide burrs are Tyrolit’s most powerful tungsten carbide burrs for cast iron, steel and stainless steel. They are based on a completely newly developed cutting edge geometry, combined with state-of-the-art coating technology. This coating makes the cutter head even more hard and produces a smoother surface — together, these factors significantly improve chip transport and increase material removal rates by up to twice that of other premium-class tungsten carbide burrs. The HPC cutters are recognisable by their unique colour combination, which is exclusive to Tyrolit. The HPC range is available in the following shapes: cylindrical (52WRC), tree-shaped (52RBF) and cylinder with face teeth (52ZYA-S), in head sizes from 6 to 12 mm — either individually or as a set comprising the three most popular shapes in 12 × 25 mm. The additional cost compared with the standard PREMIUM range is well worth it wherever tight deadlines, intensive series production or particularly hard materials demand maximum tool life and material removal rates.
Tyrolit has been developing and manufacturing tungsten carbide burrs for over 100 years as part of a global abrasives range comprising more than 80,000 products. The burr range is not developed in isolation, but as part of a comprehensive systems approach: The same manufacturing expertise that goes into precision grinding wheels for the automotive industry or diamond tools for the construction sector also shapes the development of tungsten carbide burrs — from cutting edge geometry and coating technology right through to material selection. With production and sales sites in over 140 countries, Tyrolit guarantees consistent availability and reliable on-time delivery. Technical support from experienced application engineers — on-site, at the machine — complements the product range with practical process expertise. The highest quality standards and a strong commitment to innovation, evidenced by over 500 patents, make Tyrolit a reliable partner for demanding milling tasks in the metalworking industry.
