Why Choose This Diamond Step Hole Opener?
- Exceptional Cutting Sharpness: High-density brazed diamond grain coating delivers fast, burr-free cutting performance, significantly reducing working time and boosting your construction efficiency on hard surfaces.
- One Tool, Multiple Sizes: The integrated stepped structure supports hole processing across multiple diameters in a single pass — no need to buy or swap out separate hole openers. Save on tool costs and storage space.
- Secure Angle Grinder Compatibility: Built on a high-strength carbon steel base with a standard angle grinder interface, this reamer fits most mainstream angle grinders snugly, providing a stable, shake-free connection even at high speeds.
- Ultra-Long Service Life: An upgraded high-temperature brazing process locks diamond grains firmly to the substrate for outstanding wear and heat resistance — lasting 2–3× longer than conventional electroplated hole openers, reducing how often you need to replace your bit.
- Wide Material Compatibility: The hard diamond cutting layer is engineered for tile, sintered stone, marble, granite, and ceramic — ideal for home renovation, tile laying, countertop installation, and professional stone processing.
