1 Competence with Tungsten Carbide Milling Burrs. Efficiency and individual solutions are our standard.

2 Competence Sustainable solutions are created when experience meets practical know-how. The expertise from many heads is embodied in every RHODIUS burr, namely that of our qualified work force in customer service, development and production, but above all, the application demands and application diversity of our customers. They repeatedly present us with new challenges and give us the impetus for innovative top efficiency. This practical slant, paired with our production know-how, is what makes it possible to deliver clever product solutions which achieve top results, increase the productivity of your machining processes and also provide maximum comfort during their implementation. Innovation Performance and ease of use for professionals. The demands on professional tools are the same as the demands professionals require from themselves: Face new challenges daily, deliver maximum performance under the severest of ambient conditions and demonstrate stamina. As a professional, you must be able to rely on your tools. Downtimes are just as unacceptable as performance and quality fluctuations. After collaborating with professionals for decades, we know what is important. Using this practical know-how with regard to material, machinery and machining processes, we develop tools that simplify your work by professionals for professionals. 2

3 Individuality RHODIUS is right at home where custom solutions are the standard. The bandwidth for various workpiece specifications is enormous. So are the requirements for their machining. Every product geometry and workpiece type requires special head shapes and serrations to achieve top results and a high level of efficiency in the machining process. RHODIUS always focuses on both of these. A solution is only considered to be an ideal solution once the material quality, parts geometry, machine and milling burrs are perfectly adapted to one another. We are happy to analyse your particular application on-site, individually develop the best milling burr for your requirements and also advise you on their ideal handling and how to improve efficiency. With more than 60 years of experience and a multitude of optimum solutions behind us, we no longer need to reinvent the wheel with every requirement. RHODIUS already has a diversified assortment of burrs available for various metal machining applications. Standard items are delivered in the shortest time. Individual, comfortable, quick: Customised, customer-specific product solution Flexible application support, competent on-site advice Short development time Fast availability of wide assortment of standard products What challenge do you have for us?

4 Tungsten carbide burrs Fine precision Precision is the key performance criteria for carbide burrs. This is why Rhodius carbide burrs are manufactured on the most modern CNC machines. The outstanding accuracy of these machines guarantees the constant high quality of the tool. Our carbide burrs are characterised by a high concentricity and perfectly matched cutting shape. For spoton working results. The right cut The following basic rule applies: the harder the material to be processed, the finer the cut. Cut Type of cut Preferred application Recommended working speed [m/min] unalloyed steels/cast steel Z 6 Double cut for a high stock removal with steel, cast iron and stainless steel alloyed steels, tool steels rust and acid-profeed steels cast iron unalloyed steels/cast steel Z 3 Single cut for a good surface finish with steel, cast iron and stainless steel alloyed steels, tool steels rust and acid-profeed steels cast iron for a high stock removal Z ALU with aluminium and Aluminium soft aluminium alloys, cut light metals, non-ferrous Non-ferrous metals metals and plastics Custom models We are happy to produce custom models in close collaboration with you. We also deliver various dimensions, serrations and shaft lengths in accordance with your requirements. Please do not hesitate to call us at if you require any additional information. 4

5 The recommended operating speed In order to achieve optimum working results and long lifetimes, the choice of an optimum speed is also of decisive importance. If the speeds are too low, this leads to erratic running and cavities. The consequenze is premature wear of the carbide burr. Knocking and chattering of the carbide burr also greatly reduces the lifetime. This is why you should only use truerunning chucks. Choosing the correct tool: Revolutions (rpm) Z Alu Z 3 + Z Head diameter (mm) Safety tips concerning long-shanked tungsten carbide burrs When working with long-shanked tungsten carbide burrs, please remember to insert the die into the workpiece before beginning the operation (borehole, notch, channel) and remove it again afterwards. Contact with the workpiece must be ensured while operation is ongoing. The maximum operating speeds with workpiece contact must be reduced considerably compared with the speeds recommended for tungsten carbide burrs with standard shaft lengths due to safety considerations. Non-observance can mean there is a danger of the burr snapping off, causing an increased danger of an accident industry@rhodius.de 5

6 The correct head shape is decisive The right tool for every application The choice of head shape is determined by the machining that must be done and the workpiece geometry. The most common machining processes are burr removal, milling for surface welding, re-working of welded seams, cleaning of castings and the machining of contours. It is necessary to select the milling head suitable for the contour that is to be machined, its accessibility and characteristics. The overview can assist you with selecting the suitable head shape: Milling cutter name: HF C 8 x 19 x 6 Z 6 Carbide burr shape C Form A: Cylinder without end cut ZYA Carbide burr shape Head diameter (mm) Head length (mm) Shaft diameter (mm) Cut Head diameter (mm) 8 Shaft diameter (mm) 6 19 Head length (mm) Form B: Cylinder with end cut Form C: Ball nosed cylinder Form D: Ball Form E: Oval ZYAS WRC KUD TRE Form F: Ball nosed tree Form G: Tree Form H: Flame Form J: Countersink 60 deg.
