Ecarke Diamond Grinder Bit Head Set for Stained Glass – 4 Sizes with Brass Core

Overview

The Ecarke Diamond Grinder Bit Head Set brings four precision grinding bits designed for glass and tile work. Each bit combines a chrome-plated, hardened surface with a durable diamond bonding layer, all centered on a brass core to minimize shaft binding and deliver smoother, consistent cuts.

What’s in the box

• Four diamond bits in sizes 1 inch, 3/4 inch, 1/4 inch, and 1/8 inch
• Hole diameter: 8 mm (0.31 in) for compatibility with standard tool accessories
• Four matching Allen wrenches for quick, tool-free bit changes

Key benefits and capabilities

• Versatile for forming and edging hard materials such as ceramic tiles, glass, colored glass, and stone
• Brass core design reduces shaft binding and prevents sticking to the grinder
• Chrome-plated, hardened construction with double-plated diamond bonding for improved durability and long life
