【Quick and Efficient Drilling with Low Resistance】Designed for handheld drills, these high-strength eccentric twist drill bits provide precise positioning and reduced friction. This significantly minimizes the chances of slipping or deflection during drilling, especially when working on tough surfaces like concrete, brick, and ceramic pots. These bits are engineered to deliver fast drilling performance while maintaining accuracy, making them a must-have for any serious drilling project. For optimal results, use impact mode sparingly on delicate materials.

【Industrial-Strength Cross-Head Tip】Each drill bit features a cross-head tip that enhances cutting power and precision. This professional-grade design ensures that the bit cuts through materials effortlessly, providing cleaner and more accurate holes. When working with harder surfaces such as glass or ceramic, it's recommended to cool the drill with water and control the speed for best performance and longevity of the bit.

【Wide Range of Applications for Multiple Materials】The WOYUOSN drill bits are suitable for a wide variety of materials, including glass, ceramics, tile, mirrors, flower pots, wood, porcelain, brick walls, marble, and thin metal sheets. For harder materials like ceramic tiles, marble, glass, and granite, use water to cool the bit and apply gradual pressure while maintaining a tilted angle that transitions to vertical drilling for precision and safety. This set truly offers versatility for both professional and home-use projects.
