Diamond cutter Dremel 26150662JB

The Dremel diamond cutter 26150662JB is a precision rotary accessory designed for cutting and shaping glass, ceramic, stone and other hard materials. With a small maximum hole diameter of 3.2 mm, this diamond cutter is intended for detailed work where accuracy and a fine cutting edge are required. The accessory is compatible with Dremel rotary tools and is suitable for applications that demand controlled, clean cuts in fragile or brittle materials.

Advantages

The diamond cutting surface provides high wear resistance and maintains cutting performance over repeated use. Its small cutting diameter allows for precise, intricate work and reduces the risk of cracking surrounding material when used with proper technique. The cutter is designed for consistent cutting depth and a stable fit in standard rotary tool collets, supporting reliable results in both hobby and professional projects.

Suitable for

• Creating small holes and openings in glass and glazed ceramics
• Detail work on stone and masonry tiles
• Jewellery making and beadwork involving fragile materials
• Model making and restoration tasks requiring precise cuts

Key specifications

• Cutting material: diamond abrasive surface bonded to a metal shank
• Maximum hole diameter: 3.2 mm
• Intended materials: glass, glazed ceramic, stone, and similar hard brittle materials
• Compatibility: for use with Dremel and comparable rotary tools with matching collet size
• Design focus: precision cutting, small-diameter hole creation, and fine shaping

How to use

Install the diamond cutter into the rotary tool collet according to the tool manufacturer’s instructions, ensuring a secure and concentric fit. Use low to moderate speed settings and apply light, steady pressure to avoid overheating and chipping; for glass or ceramics, coolant or intermittent cutting with water can reduce dust and heat build-up. Move the cutter slowly and make several passes rather than forcing a single deep cut. After use, clean the cutter by rinsing with water and gently removing debris to preserve abrasive performance.

Usage recommendations

For best results, wear appropriate personal protective equipment such as safety glasses and a dust mask, and clamp workpieces securely. When cutting glass or ceramic, keep the cut area wet or pause frequently to allow cooling. Match speed and pressure to the material: lower speeds and light pressure for delicate items, moderate speed for harder stone. Regularly inspect the cutter for wear and replace when the abrasive performance declines to maintain precise cuts.
