DUAL-STEP™ 1-3/8″ (35mm) Diamond Core Bit with Beveling Flange (5/8″-11)
Drill and bevel in one seamless motion. The Ioan DUAL-STEP™ is a heavy-duty hybrid tool designed for maximum efficiency. Featuring a premium vacuum-brazed core bit integrated with a coarse diamond beveling flange, it allows you to drill a perfect hole and immediately create a chamfer without changing tools.
-
2-in-1 Design: Simultaneously drills and creates a 45° bevel for a professional finish.
-
Edge Protection: The integrated flange reinforces the hole edge and prevents cracking under stress.
-
Efficiency: Eliminates tool changes, saving time on high-volume installations.
-
Build: High-concentration diamond grit for fast cutting and aggressive material removal.
The Ioan DUAL-STEP™ 35mm Core Bit is engineered for contractors who value speed and precision. This specialized bit is perfect for plumbing and electrical fixtures where a clean, countersunk hole is required. The diamond-coated flange not only creates an aesthetic chamfer but also smooths out micro-chips around the hole, significantly reducing material tension. Designed for dry use on angle grinders, it provides a stable and non-aggressive drilling experience in the hardest porcelain, granite, and marble.
