Overview

Enhance your stained glass projects with Ecarke Diamond Grinder Bit Head Tools. Built for precision, these bits pair a chrome-plated, hardened drill tip with a brass core to reduce shaft binding and keep your grinder running smoothly. The diamond-coated surface is double plated for strength, delivering clean, consistent cuts as you work through glass, ceramic tile, and other hard materials.

What’s included

• Four diamond grinding bits in sizes 1 inch, 3/4 inch, 1/4 inch, and 1/8 inch
• Four matching Allen wrenches to fit most glass grinders

Design, materials, and durability

The bits use a standard frosted design for predictable cutting results, with a brass core that minimizes shaft binding and prevents sticking to the grinder shaft. The drill tips are chrome-plated and hardened for long-lasting performance, while the diamond abrasive coating is double plated to resist wear and maintain edge integrity throughout use. The bore measures 8 mm (0.31 in), supporting a steady, controlled grind across a range of tasks.
