Dremel 7134 Rotary Tool Bit

The Dremel 7134 rotary tool bit is a diamond-coated precision bit designed for fine detail work, cutting, engraving, carving, touch-up and finishing on hard materials. With a shank diameter of 3.2 mm, an overall length of 46 mm and a working diameter of 2 mm, this bit supports high-speed use up to 25,000 RPM. The pack contains 2 pieces suitable for hobbyists and professionals who require accurate, durable bits for small-scale tasks.

Advantages

Diamond particle coating provides long-lasting cutting and grinding performance on hard surfaces. The 3.2 mm shank fits standard rotary tools and allows stable, precise operation. Compact 2 mm diameter enables detailed work and fine lines, while the 46 mm length offers reach and control. Supplied as a two-piece pack for replacement or multiple operations.

Suitable for

• Precision cutting and fine detail engraving
• Carving and shaping hard materials such as wood, jade and ceramics
• Touch-up and finishing on glass, semi-precious stones and hardened steel

How to use

Install the Dremel 7134 bit into the collet of a compatible rotary tool with a 3.2 mm chuck or collet. Secure the bit, set an appropriate speed (up to 25,000 RPM depending on material and tool recommendations) and perform light, controlled passes. Apply minimal pressure—let the diamond coating do the work—to avoid overheating or premature wear. Use proper fixtures or clamps for small workpieces to maintain accuracy and safety.

Recommendations

Wear eye and respiratory protection when cutting or grinding hard materials. For best results on glass, ceramics and stones use moderate speeds and steady feed; for hardened steel reduce speed and use light, incremental passes to prevent heat buildup. Replace the bit when cutting performance visibly declines.
