High-Cobalt Alloy for Superior Durability

Made of high-grade cobalt alloy, our carbide drill bits outperform traditional YG6X alloy bits in overall quality. The premium material greatly enhances wear resistance and effectively extends the service lifespan. Even after repeated use on hard materials, the drill bits maintain stable cutting performance, saving your cost on frequent replacements and bringing excellent long-term value.

Serrated Design for Accurate & Smooth Drilling

Each tile drill bit is engineered with a unique serrated structure, which optimizes chip removal during operation and prevents debris from blocking the bit. Combined with the anti-slip design, the drill stays steady while working. You can effortlessly create clean, neat and highly accurate holes without deviation, greatly improving your working efficiency and drilling results.

Wide Application & Professional Operation Tips

Our multi-functional drill bits are suitable for a wide range of materials, including glass, ceramic, tile, mirror, plant pots, wood, porcelain, brick wall, marble and thin iron plates. For drilling hard glass and tiles, we recommend operating at a constant speed of 400-600 RPM without water cooling. If you add water for lubrication and cooling, adjust the rotational speed to 500-800 RPM to achieve the best drilling effect and protect both the drill bits and workpieces.

Combining complete sizes, durable materials, precise cutting performance and universal compatibility, our 10pcs serrated carbide drill bit set is a practical essential for every toolbox. No matter for professional construction jobs or household DIY tasks, these masonry and tile drill bits will always be your trustworthy partner.
