Feature:

1. Wide Applications: This highly wear-resistant drill bit is designed for expanding, chamfering, and smoothing holes in hard materials like marble, granite, quartz, tile, and concrete.
2. Three Hole Sizes: The drill bit features a multi-layered tip and three-stage reaming design. It includes three different sizes (20mm, 35mm, and 50mm) to cover a wide range of applications. You'll have the right size for the job.
3. Unmatched Durability: Made from high-manganese steel with superior toughness and resistance to deformation and particles for long-lasting performance. This multi-layer brazed hole opener maintains its shape and functionality even under heavy use.
4. Dry and Wet Operation: Designed for both dry and wet cutting. Dry cutting is ideal for quick tasks and indoor projects, while wet cutting helps reduce dust and heat, extending the life of the tool and ensuring a smoother finish.
5. Attachment to 100mm Angle Grinder: Our hole opener features an extended thread interface that is specifically designed to fit 100mm angle grinders. It can also work with hand drills, and a transfer rod is needed.
