Diamond cutter Dremel 26150663JB

The Dremel 26150663JB diamond cutter is a precision rotary accessory designed for clean, accurate cutting in glass, ceramic, stone and similar hard materials. With a compact cutting head and diamond-coated edge it enables controlled material removal and reliable hole-making up to a maximum diameter of 6.4 mm. The cutter is intended for use with compatible Dremel rotary tools and offers consistent performance for both DIY projects and professional tasks that require fine, repeatable cuts.

Advantages

This diamond cutter delivers high wear resistance and long life thanks to its diamond-coated cutting surface, keeping cutting performance stable over multiple uses. Its small cutting diameter provides precise control for detailed work and reduces chipping on brittle materials. The accessory is simple to mount on standard rotary tool collets, and its balanced design helps maintain smooth rotation and accurate hole placement.

Suitable for

• Making small-diameter holes in glass and glassware
• Cutting and shaping ceramic tiles and porcelain
• Detail work in stone, marble and similar hard materials
• Model making and DIY craft projects requiring precise holes

Key specifications

• Cutting material: diamond-coated cutting edge
• Maximum hole diameter: 6.4 mm
• Compatible with rotary tools using standard collet mounts
• Intended materials: glass, ceramic, stone and similar hard substrates

How to use

Install the diamond cutter into the rotary tool following the tool manufacturer’s instructions, ensuring the bit is securely tightened in the collet. Select an appropriate rotational speed for the material—moderate speeds are generally recommended for glass and ceramic to reduce heat build-up. Use steady, light pressure and keep the workpiece supported and stable. For through-holes or deep cuts, work progressively and avoid forcing the cutter; periodic cooling with water or a cutting fluid can extend tool life and reduce chipping.

Recommendations

Wear appropriate eye and hand protection and ensure the work area is well ventilated. For best results on brittle materials, consider using a guide or jig to maintain perpendicular alignment, apply light consistent pressure, and periodically cool the cutting zone with water. Verify compatibility with your rotary tool and use the recommended collet size to secure the cutter.
