Grewin Golden Bull – Type G Rotary Burr · Ultra-Precision Long Taper Tool
The Type G Rotary Burr from Gwei Golden Bull features a long, sharp taper design, making it the most specialized model for machining sharp corners and small-radius internal fillets. It can penetrate millimeter-scale gaps and narrow spaces where other rotary burrs cannot reach, delivering micron-level precision machining. Known as the “ultimate weapon” for fine detail work.
Key Features:
- Carbide Material: Exceptional hardness and wear resistance, ensuring the slender tip remains sharp and durable without breaking easily.
- Wide Application Range: Suitable for metals with hardness ≤ HRC55 (carbon steel, alloy steel, stainless steel, etc.).
- Double-Cut Taper Design: Slender taper shape with cross-cut fluting, offering outstanding penetration and ultra-high precision.
- Professional Performance: Ideal for fine machining, sharp-corner detailing, and high-precision repairs. Widely used in mold making, precision instrument maintenance, aerospace, medical devices, and the electronics industry.
- Premium Qualities: Sharp cutting edges, burr-free finish, wear and heat resistance, and support for non-standard customization.
Usage & Maintenance Guidelines:
- Safety Protection: Wear safety goggles and cut-resistant gloves to avoid debris injury.
- Regular Cleaning: Remove debris frequently to maintain optimal cutting performance.
- Moderate Force: Avoid excessive pressure to prevent overheating or premature wear; reduce RPM when using extended shank burrs.
- Speed Control: Designed for high-speed operation; adjust RPM according to the material and use cooling where necessary.
Application Case | Improved Efficiency in Aerospace Component Repair
- Customer Background: An aerospace maintenance facility needed to deburr turbine blades (nickel-based alloy). Conventional burrs wore out quickly and required frequent replacement.
- Optimized Solution: Recommended Ultra-fine Grain Carbide K-Series (taper type) Rotary Burr with coating, adjusted to 25,000 RPM with minimal lubrication cooling.
- Customer Feedback: Tool life extended by 3×! A single burr processed 50 blades, achieving a surface finish of Ra0.8 μm, eliminating the need for additional polishing.
