Powerhouse for the toughest jobs and maximum chip removal – the V4 Purple Power lamellar flap disc from the LUKAS-ERZETT iQ series.

The demands placed on industrial grinding processes have increased enormously in recent years – and this is precisely where the iQ series from LUKAS-ERZETT comes in. With more than 85 years’ experience in developing and producing high-quality tools and special solutions for milling, grinding, polishing, cutting, drilling and cleaning, LUKAS-ERZETT now provides its customers with a tool that sets standards in terms of removal rates and tool life with the V4 Purple Power lamellar flap disc.
The new lamellar flap disc is a member of the high-performance iQ tool family, which is characterised by top quality, extreme resilience and ergonomic advantages.
Developed for maximum removal rates, its outstanding features are the arrangement of the lamellar flaps, the flap shape with abrasive grain made of high-performance ceramic and the optimum grain dispersion. This flap disc grinds materials such as steel, stainless steel, cast material and titanium at effortless speed and the highest level. The LUKAS V4 Purple Power lamellar flap disc not only offers extremely high removal rates, but is also very quiet and safe to work with – even at high speeds on high-performance power tools, as well as on robotic grinders and automatic grinding machines.
Like all tools from the iQ series, the V4 Purple Power flap disc meets the most stringent quality standards and is regularly tested.
This results in fewer tool changes, consistent performance and less wear. The sturdy design prevents grain shedding – even during prolonged use or on hard materials.
In short: the LUKAS V4 Purple Power lamellar flap disc is impressive in every respect. It delivers greater productivity, lower tool costs and a huge increase in efficiency.
Technology that makes the difference and ensures extremely high removal rates. The V4 Purple Power lamellar flap disc from LUKAS-ERZETT.
Behind the impressive performance of the LUKAS V4 Purple Power lamellar flap disc is much more than just aggressive abrasive grain made from high-performance ceramic. The decisive factor is the clever tool architecture specifically designed for maximum tool life and efficiency. The key here is the original LUKAS sickle-shaped flap. Every single flap is arranged and bonded so that it adapts perfectly to the workpiece, wears evenly and continuously exposes new abrasive grains. This guarantees a constant, extremely high removal rate – even on the most demanding materials and during prolonged work.

Another advantage is that the abrasive coating has multiple layers, which means that fresh abrasive material is automatically exposed under the worn flaps as the work progresses. The LUKAS V4 Purple Power lamellar flap disc therefore remains as sharp as the first time it was used throughout its entire tool life. In everyday use, this means fewer tool changes and downtimes, resulting in lower costs and greater productivity.
The V4 Purple Power is based on a robust steel backing plate developed exclusively by LUKAS which offers maximum stability. That makes this LUKAS flap disc especially suitable for use on robots, automatic grinders and powerful angle grinders. The special resin bonding of the lamellar flaps ensures absolute process reliability even at high temperatures and speeds. The design is complemented by a ceramic abrasive grain of the latest generation. The self-sharpening, high-performance ceramic grain is particularly hard-cutting and hard-wearing. During grinding work, single particles systematically break off and expose new, sharp cutting edges – keeping the removal performance at a consistently high level. Combined with the open grain dispersion and optimised heat dissipation, the result is cool, low-vibration grinding with outstanding surface results.
In other words, the technical design of the LUKAS V4 Purple Power lamellar flap disc was conceived down to the last detail for maximum efficiency and removal rates – resulting in a high-performance tool that sets standards. Whether on titanium, stainless steel, cast material or hardened surfaces, the LUKAS V4 Purple Power lamellar flap disc lets users master even the toughest jobs with ease. And with consistently high performance throughout the entire tool life.
Record-breaking removal rates in record times – how the LUKAS V4 Purple Power lamellar flap discs perform in practice.

Users who want to achieve maximum productivity with industrial grinding applications cannot do without a tool like the V4 Purple Power lamellar grinding disc from LUKAS-ERZETT. Its impressive performance is not only reflected in the technical data – but above all in practice. One example: in documented use on a robot, more than 23 kilograms of steel were removed in just five and a half hours using a single LUKAS V4 Purple Power lamellar flap disc with a diameter of 125 mm. This corresponds to a continuous removal rate of more than four kilograms of steel per hour over an extremely long period of use, which is significantly better than the performance of conventional tools. This is combined with significantly lower noise levels, less vibration and lower heat generation.
What makes the LUKAS V4 Purple Power flap disc so special is the combination of a clever flap architecture, the original LUKAS sickle-shaped flaps, the self-sharpening capability, high-performance ceramic grain and the robust steel backing, which does not give way even under extreme loads.
The grinding flaps are arranged to maximise the number of abrasive grains in the outer area where the material is being removed. At the same time, the abrasive coating remains constantly sharp thanks to the multi-layer structure. As soon as a flap wears down, fresh grain on the underlying flaps is automatically exposed. This principle ensures extremely high and consistent removal rates.
The LUKAS V4 Purple Power lamellar flap disc also displays its full strength on challenging materials such as hardened steel, titanium, reinforced weld seams or hard coatings. Thanks to its high thermal load capacity and optimised heat dissipation, the tool works reliably, safely and efficiently even at high speeds or in automated grinding processes. In short: users who want to remove more steel more quickly should choose the V4 Purple Power lamellar flap disc from LUKAS-ERZETT. In terms of removal performance, it is practically unrivalled in its class.
