Description Technical Specs
 

Our High Speed Steel (HSS) Cylinder Bur #16 (4mm) is precision-engineered from superior quality M2 High Speed Steel, ensuring exceptional durability, performance, and longevity. Designed for professional jewelers, metalworkers, and precision craftsmen, this bur delivers smooth, accurate cutting action and maintains its sharp edge even under heavy use.

Features & Benefits:

  • Premium M2 High Speed Steel: Provides superior wear resistance and longer lifespan compared to Tungsten, Vanadium, or Carbon Steel burs.

  • Spiral-Cut Flutes: Efficiently channel away debris, reduce loading, and deliver smoother cutting and grinding performance.

  • Cylinder Shape: Ideal for flat-surface work, enlarging holes, refining edges, and removing material from inside ring shanks.

  • Versatile Applications: Perfect for use on metals, carving wax, wood, plastics, and other jewelry materials. Commonly used in wax ring model carving, jewelry resizing, and precision detailing.

  • Standard 3/32" (2.35mm) Shank: Compatible with most flex shaft handpieces and rotary tools using adjustable chucks or collets.

Features
  • Premium High Speed Steel (HSS) Construction: Crafted from industrial-grade M2 High Speed Steel for superior hardness, durability, and resistance to wear and heat buildup — ensuring consistent performance over time.

  • Sharp, Precision-Cut Flutes: The cross-cut cylinder head provides exceptional cutting control, fast material removal, and smooth finishes on a wide range of materials including metal, wax, wood, and plastics.

  • Sharp, Pointed Cutting Edges: Designed with precision-ground cutting edges for detailed engraving, shaping, and refining work — ideal for jewelers and fine metal artisans.

  • Cylinder Shape for Versatility: The flat-end cylinder profile is perfect for grinding, flattening surfaces, enlarging holes, and reshaping inner curves such as ring shanks and cavities.

  • 3/32" (2.35mm) Standard Shank: Universally compatible with most rotary tools, micromotors, and flex shaft handpieces used in jewelry making, metalworking, dental labs, and crafts.

  • Cross-Cut Pattern for Efficiency: Features a double cross-cut flute design that minimizes clogging, enhances chip evacuation, and provides superior control even at high speeds.

  • High-Speed Performance: Operates effectively at speeds up to 50,000 RPM, maintaining stability and precision under demanding conditions.

  • Long-Lasting Durability: Engineered for extended tool life — resists dulling and deformation, even during continuous use on tough materials.

  • Precision Balanced for Smooth Operation: Each bur is centrically balanced to minimize vibration, reduce operator fatigue, and deliver a cleaner, more accurate cut.

  • Multipurpose Use: Ideal for engraving, shaping, deburring, texturing, and refining work on gold, silver, platinum, brass, steel, wax models, and more.

  • Corrosion & Heat Resistant: The HSS material provides high thermal stability and oxidation resistance, ensuring reliable performance during prolonged use.

  • Professional-Grade Quality: Trusted by jewelers, dental technicians, model makers, and precision craftsmen for consistent, high-quality results.
