Delphi Tools QTOD-M14/68 Diamond Hole Saw 68mm M14

The Delphi Tools QTOD-M14/68 is a professional-grade 68mm diamond hole saw engineered for high-precision drilling in demanding materials. Featuring a standard M14 mounting thread, this tool integrates seamlessly with most angle grinders, providing a stable and efficient solution for creating clean, circular openings. The high-quality diamond-coated edge is specifically designed to withstand the rigors of heavy-duty construction and renovation work, ensuring consistent performance and a long operational lifespan.

Advantages

This diamond hole saw offers exceptional durability due to its robust construction and high-density diamond grit, which allows for rapid material removal without compromising the integrity of the workpiece. The M14 thread connection ensures a secure fit on standard power tools, minimizing vibrations and enhancing control during the drilling process. Its design facilitates smooth operation, resulting in precise edges that require minimal post-drilling finishing, making it an essential tool for achieving professional results in various hard surface applications.

Suitable for

• Drilling holes in ceramic and porcelain tiles
• Working with natural stone surfaces
• Renovation projects requiring precise electrical box cutouts
• Professional construction and interior finishing tasks

When it may not be suitable

This tool is not intended for drilling through metal, wood, or soft plastics, as these materials can clog the diamond segments and cause overheating. It is also not suitable for use with standard drills that lack an M14 spindle unless a specific adapter is utilized.

Key specifications

• Diameter: 68mm
• Mounting type: M14 thread
• Cutting material: Diamond coating
• Compatibility: Angle grinders

How to use

To use the hole saw, securely mount it onto the M14 spindle of your angle grinder. Begin the drilling process at a slight angle to establish a starting groove, then gradually straighten the tool to a perpendicular position while maintaining steady pressure. It is recommended to use a circular motion during drilling to improve dust extraction and cooling. Ensure the angle grinder is set to the appropriate speed for the material being processed.

What to consider before purchase

• Verify that your angle grinder supports the M14 mounting thread
• Ensure the 68mm diameter meets your specific project requirements
• Confirm the material hardness is compatible with diamond-coated tools

Usage recommendations

For optimal performance and to extend the life of the diamond segments, allow the tool to cool periodically during extended use and avoid applying excessive force. Using a template or guide can help maintain precision when starting the hole.
