Review on Raizi Diamond Finger Milling Bits For Enlarging Shaping Holes On Porcelain Tile Marble Granite Milling Tools 2 Pcs (10Mm(3/8 Inch)) by David Golden

The diamond coating on the bits makes them durable and long-lasting, but it also means they can be a bit aggressive on softer materials, such as ceramic tiles. Additionally, the bits can generate a lot of heat, so it's important to use them at a slow speed and with plenty of water for cooling. Overall, the Raizi Diamond Finger Milling Bits are a decent choice for professionals or DIY enthusiasts, but they may not be the best fit for every project. It's important to take care when using them to avoid damaging your materials and to ensure the longevity of the bits themselves.
