High Speed Steel (HSS) Flame Burs, size 28 (7.2 mm), are premium-grade rotary cutting tools engineered for accuracy and long-lasting performance across multiple materials and applications. Manufactured from industrial-quality high-speed steel, these burs deliver exceptional cutting efficiency, heat resistance, and edge retention — even under continuous use in demanding environments.
Key Features & Benefits:
-
Superior Material Quality: Made from premium HSS for enhanced hardness and wear resistance, ensuring a longer tool life compared to standard steel burs.
-
Unique Flame Shape: The tapered flame profile allows for precise shaping, contouring, and smoothing, ideal for detailed work in hard-to-reach areas.
-
Versatile Applications: Suitable for metalworking, woodworking, jewelry making, stone carving, and model engineering, offering excellent performance on steel, aluminum, hardwood, and composite materials.
-
Smooth & Efficient Cutting: Provides clean, burr-free finishes with minimal vibration, ensuring greater control and reduced operator fatigue.
-
Heat & Corrosion Resistance: Maintains sharpness and strength under high temperatures, making it perfect for high-speed rotary tools and die grinders.
-
Professional & DIY Use: Trusted by machinists, artisans, and hobbyists alike for precision shaping, engraving, and surface finishing tasks.
