Offset Tile Drill Bits: These drill bits feature two cutting edges on one side and only one on the other, creating an offset design. As the drill rotates, the two edges alternately cut the tile surface, combining the stability of a Phillips head drill with the sharpness of a single-edged drill. Dry Concrete Drill Bits: Designed for low-speed drilling, these bits utilize tungsten carbide tips for better heat dissipation and durability. They provide efficient and precise drilling when drilling above water is inconvenient. New Masonry Drill Bit Set: This set includes five sizes of drill bits: 1/4 inch, 5/16 inch, 3/8 inch, 1/2 inch, and 9/16 inch (6 mm, 8 mm, 10 mm, 12 mm, and 14 mm). The total length is 3.5 inches/88 mm, with a maximum drilling depth of 2 inches/50 mm. Carbide Drill Bit Set: This multi-purpose drill bit is ideal for drilling into a variety of hard materials, including marble, porcelain, ceramics, slate, concrete, and red brick. When working with hard materials, water cooling is essential to extend the drill bit's lifespan and maintain its sharpness. Wide Compatibility: The 1/4-inch hexagonal shank at the end of the drill bit is compatible with common tools such as hand drills, bench drills, and impact drills. Use with drills operating below 24V is not recommended. The optimal drilling speed is 500 rpm, which can be adjusted as needed. When drilling into concrete walls, be careful of reinforcing steel to prevent the drill bit from getting stuck or breaking.
