The Oma Router Bit B Demi Bullnose in 2 cm and 3 cm sizes offers outstanding lifespan and a smooth finish on marble, granite, quartz, and engineered stone. Here's why OMA position 1 profile bits are worth the investment. Firstly, most router bits today have a diameter of about 2 3/4 inches, but OMA bits are almost 3 1/2 inches in diameter, providing 30% more diamond. This larger diameter changes the surface feet per minute of profiling, allowing for faster cutting. Secondly, these bits are made in Italy by OMA, with full - control over production quality, ensuring they meet 100% optimum performance standards. Thirdly, the pos 1 bits are made of solid brass. They're designed to last for years, and OMA offers replacement segment kits. You can easily replace the segments and get a brand - new bit at 40% of the original cost, with premium quality. Fourthly, the center water feed feature guarantees continuous water on the bits, preventing accidental 'dry cut' and protecting both the bit and the stone. Fifthly, OMA bits don't experience thermic stress from the welding process, resulting in a long life, even wear, and a smooth finish. Sixthly, they leave the stone smooth and chip - free, ready for pos 2 profile bits or hand - polishing. Lastly, due to their quality and longevity, you can save 30% - 50% over a year compared to smaller - diameter contour rim bits on the market. The OMA Prodiam position 2 profile router bits use diamond brazed technology. They can be used as pos 1 on marble, limestone, and travertine, or as pos 2 after Oma Pos 1 on granite and other stones. They're made with a steel core and brazed diamonds, creating a perfect shape and providing a long - lasting position 2. The OMA Extradiam position 3 profile router bits are extra - fine diamond profile wheels that start the polishing process. They're the bridge between profiling and polishing, with a steel core and high - density extra - fine abrasive diamond powder. The recommended RPM is 2500 - 3500, with an optimum of 3000. The OMA True Life polishing wheel uses patented sintered and electroplating processes, offering maximum polishing results and a long life. It matches the metal diamond profile wheels 2 and 3, removes scratches, and can be used on all kinds of stone. The recommended polishing speed is 2500 - 6500 RPM, with optimum results at 3000 RPM. All OMA bits are made in Italy with strict quality control and have the center water feed feature.
Using these OMA router bits is straightforward. For the position 1 bits, just install them on your router as you would with any other bit. Make sure to connect the water supply to take advantage of the center water feed feature. This helps keep the bit cool and prevents dry cutting. When using the position 2 Prodiam bits, you can use them directly on marble, limestone, and travertine as the first step. Or, after using the position 1 bit on granite and other stones, use them to refine the shape. The position 3 Extradiam bits are for starting the polishing process. Set your router to a RPM between 2500 - 3500, with 3000 being the best. And for the True Life polishing wheels, use them at a speed of 2500 - 6500 RPM, aiming for 3000 RPM for the best results. As for maintenance, regularly check the bits for any signs of wear. If the segments on the position 1 bits are worn out, use the replacement segment kits provided by OMA. Simply unscrew the old segments and install the new ones. Always keep the bits clean and dry when not in use. Also, make sure to store them in a safe place to avoid any damage. And remember, always follow the safety guidelines when using power tools.
