Why customers choose TaskHolt Tools

Product overview

Meet the DT-DIATOOL Diamond Beveling Chamfer Bit, a compact 2 inch working length tool designed for use with a 5/8"-11 thread angle grinder. This bit excels at enlarging or shaping predefined holes in porcelain tile, hard ceramic tile, granite, and marble. Built to trim, repair, and refine hole edges, it helps you achieve clean bevels and smooth edges without swapping to multiple tools.

Key capabilities

This bit is purpose-built for manipulating existing holes and edges, not for starting new holes. Its diamond grit provides controlled material removal, enabling gradual enlargement and gentle beveling for a polished look. Ideal for scenarios where you want to maintain precision while preserving surrounding tile integrity.

  • Enlarges or shapes existing holes in tough stone and tile materials
  • Rounds bevels and grinds edges for a refined finish
  • Designed for porcelain tile, hard ceramic tile, granite, and marble
  • Works in tandem with diamond finger milling bits, diamond drill bits, or diamond blades/discs

Why this tool stands out

  • Economical workflow: with one standard core bit plus this finger bit, you can achieve many hole sizes without buying multiple cores
  • Compatibility: 5/8"-11 thread ensures broad compatibility with popular angle grinders and accessory sets
  • Precision-focused design: the 50 mm diameter (2 inch) tooling length and 46 mm usable length help you control depth and edge quality

Usage tips and safety notes

Note that this tool is not designed for drilling new holes. Using it as a drill can dramatically shorten the bit’s life. For best results, pair this bit with appropriate diamond finger milling bits or diamond drill bits/discs, and use steady, controlled passes to maintain edge integrity. Always wear eye protection and follow grinder manufacturer guidelines.

What you gain

  • Better control over hole size and edge appearance on natural and engineered stone
  • Reduced need for multiple tools when working with existing openings
  • A versatile option for trimming, repairing, and finishing around holes in tile and stone surfaces
