15PCS Diamond Drill Bit Set 6mm-50mm Tile Marble Glass Ceramic Hole Saw Drilling

This set includes 15 diamond-coated drill bits designed for precise drilling in various materials such as glass, tile, marble, ceramic, and stone. Made from high-strength carbon steel with a smooth nickel-plated surface, these bits offer reduced resistance and enhanced durability. They are suitable for creating clean, accurate holes with water lubrication to improve performance and lifespan.

• Diamond drill bits start diagonally, form a round weave, and then drill straight. Water is required for lubrication during drilling.
• Ideal for drilling holes in glass, tiles, bottles, blocks, jars, fiberglass, porcelain, ceramics, slate, marble, and light stone.
• Each drill bit features a smooth, accurate finish that reduces cutting resistance and increases sharpness, especially when used with water lubrication.
