6-Piece Eccentric Bit Set, 4/5/6/8/10/12mm Carbide Tip Bits, High Hardness Angled Head Drill Bits, Four-Flute Serrated Drill Bits, for Wood, Masonry, Tiles

【High-Quality Materials】This random orbital drill bit with four flutes and saw teeth is made of high-performance, ultra-hard alloy, offering excellent hardness and strength. It is finely polished and rust-resistant to ensure precise, burr-free drilling. 【Multiple Sizes】You will receive six random orbital drill bits with angled heads in different sizes: 4/5/6/8/10/12 mm. The random orbital drill bits adapt to various opening diameters and applications, allowing you to easily complete all your tasks. 【Unique Design】This random orbital drill bit features four reinforced cutting edges that automatically adjust the cutting angle to increase drilling speed and ensure a long service life. Its unique threading ensures a precise and clean cut. 【Easy Drilling】The eccentric design of this tile drill bit reduces the force required to drill through hard materials, ensures smooth operation, and minimizes wear on both the bit and the material, while providing excellent accuracy for consistent drilling and tapping results. 【Wide Application】The tungsten carbide drill bit is suitable for a variety of materials, including tile, ceramic, glass, marble, concrete, and stainless steel. For harder materials such as tile, marble, glass, and granite, use water to cool the drill bit and apply gradual pressure while maintaining the bevel and transitioning to vertical drilling to ensure accuracy and safety.
