Dremel 662DR 1/8-Inch Glass Drilling Bit

The Dremel 662DR is a diamond-impregnated bit designed specifically for glass. Its cutting edge is formed by diamond particles that provide long life and exceptional performance when drilling through both flat and contoured glass surfaces. The diamond grit wrapped around the circumference sustains rasping action, which can help create a larger hole if you need to widen a gap without switching tools. Ideal for hobbyists and professionals who prioritize precise, clean holes with minimal breakout. Compatible with standard 1/8-inch shank rotary tools, it delivers consistent results in glass cutting projects.
Durability is a key feature here: the diamond-impregnated design reduces wear and maintains sharpness over multiple uses. This bit is particularly useful for projects like installing glass hardware, making pilot holes for decorative inlays, or creating openings for cabling. For best results, maintain steady motion and a gentle feed rate to minimize heat buildup and cracking. This bit excels when used with a quality cutting fluid or water source to prolong tool life and edge quality.
Diamond Burr Set for Dremel Rotary Tool (32pc)

This diamond burr set from HOMEIDOL offers a versatile collection for glass, tile, and stone work. Each burr is engineered with diamond particles for precision grinding, carving, and internal shaping on hard materials. The kit includes a universal shank (0.118 inches / 3 mm) that fits most rotary tools and two mandrels that stabilize blades for more controlled carving. The bits are robust and designed for fine detail work, making them a great choice for jewelry engraving, tile work, or decorative glass embellishments. The set’s durability helps sustain sharpness during prolonged sessions.
Users should expect reliable performance across a range of tasks—from sculpting small glass accents to routing precise grooves in ceramic tile. The included burr shapes cover multiple angles and profiles, enabling intricate detailing without constantly changing bits. Careful handling and proper cooling during operation will extend bit life, especially when working with dense or tempered glass. This kit is well-suited for hobbyists who want a broad selection of burrs without purchasing individual pieces.
Dremel 735-01 Glass Etching Rotary Tool Accessories Kit

The 735-01 kit bundles Dremel’s most popular carving, etching, grinding, cleaning, and polishing accessories into an eight-piece set. It emphasizes carving and engraving with diamond wheel points that excel at fine, detailed work on glass, wood, ceramic, and hardened steels. The package also includes grinding stones for deburring and general material removal, helping to prepare glass surfaces before etching or engraving. This kit is a strong option for artists and DIYers who want a single, cohesive bundle for creative glass projects and surface preparation.
With a focus on versatility, the 735-01 enables both decorative etching and practical shaping. Diamond wheel points deliver crisp lines, while grinding stones support broader shaping tasks. When used with care, the kit produces professional-looking results on glass and other hard materials. Proper storage in the included carry case helps maintain organization and readiness for your next project. It’s particularly suitable for beginners who want reliable tools that cover multiple steps in the glass finishing process.
Dremel 729-01 Engraving Kit

The 729-01 kit turns a Dremel into a compact carving and engraving machine. This 11-piece collection includes a variety of engraving bits in multiple thicknesses and shapes, plus two diamond wheel points for precision detailing. The kit is designed for use on several materials, including glass, wood, plastic, and metal, making it ideal for artists who want to experiment with glass etching, monograms, or decorative motifs. A reusable storage case helps keep parts organized and accessible during long sessions.
Carving and engraving tokens in glass requires steady control and a light touch. The included bits are optimized for fine lines and delicate shading, while the diamond wheel points provide long-lasting performance on hard surfaces. The kit’s breadth makes it a good long-term investment for makers who regularly explore decorative glass work and mixed-media projects. Always observe safety guidelines and maintain cool cutting conditions to preserve both bit life and glass integrity.
120Grit Diamond Grinding Bits For Glass

This 120-grit set from YURINWOO features diamond grinding bits designed for fast material removal with glass, ceramic, stone, and jewelry-grade work. The full-diamond-coated edges offer sharp, consistent cuts, while breathing holes help dissipate heat and debris to extend tool life. The kit comes with a 32-piece assortment and an upgraded organizer to keep each bit in its place, which reduces search time during projects. It is well suited for precise slotting, engraving, or shaping details in hard materials where a clean, smooth finish is required.
In practice, the 120-grit bits provide a balance between material removal and control, making them suitable for a range of glass-related tasks—from cleaning up edges to creating intricate grooves. The varied shapes within the set cover multiple angles and profiles, enabling more versatility without needing to swap bits constantly. For best results, work slowly, apply even pressure, and keep the workpiece cool to avoid thermal stress that can crack glass.
Buying Guide
Key purchase considerations
- Project type: Decide whether your priority is drilling holes, engraving, etching, or general shaping. Some kits blend these tasks, while others focus on a single function.
- Bit material: For glass, diamond bits typically outperform carbide or steel. Diamond offers longer life and cleaner edges on hard surfaces.
- Grit and edge design: Fine grits (like 60–120) are ideal for detail work and smooth finishes, while coarser grits remove material faster but require more control.
- Shank size and compatibility: Most Dremel tools use a 1/8″ shank. Confirm that the bit fits your rotary tool and any adapters you plan to use.
- Heat management: Glass tasks generate heat. Look for bits with good heat dissipation (vented discs, water cooling options, or diamond edges designed to stay cool).
- Included accessories: Sets with mandrels, storage cases, or multiple bit shapes offer value and versatility for varied projects.
- Safety and maintenance: Wear eye protection and a mask for dust; clean bits after use and store them properly to maintain performance.
