Description [Meet all your needs]: The package includes 1 set of drill bits (3mm, 4mm, 5mm, 6mm, 8mm, 10mm, and 12mm). Tile drill bits in 7 sizes meet your needs for various drilling applications. They help with drilling by starting with the smallest bit and progressing to the required size. [Durable material]: Our carbon steel + YG8C alloy drill bit kit is made of an improved, thickened, hard, and durable alloy with anti-rust treatment, providing a long service life and higher hardness than ordinary drill bits. Chips and drill bits are also combined, and the pointed tip design is more convenient to use, saving time and enabling fast drilling. [Crosshead design]: Thanks to the sharp drill bit and crosshead design, cutting resistance is low and the opening speed is fast. Easy to position. With the tile drill bit, all drill holes are highly precise and smooth. The thread helps the drill bit effectively remove debris during high-speed rotation. [Sharp and wear-resistant]: The triangle drill bit is sharp and wear-resistant, making it ideal for drilling mounting holes on bathroom tiles or wall mirrors. [Widely used]: The drill bit set is ideal for drilling in all types of materials, including ceramic tiles, concrete, tiles, brick, wood, plastic, glass, masonry, and much more. Note: When drilling hard materials (glass, porcelain tiles, marble, or granite), please use water for lubrication.
