• [Precision-Ground Cutting Edges]：CNC-machined triple-flute design with 90° chamfer angle delivers razor-sharp cutting performance. Titanium nitride coating enhances hardness to HRC 62-65 for extended tool life.
• [Enhanced Material Compatibility]：M35 cobalt steel construction withstands temperatures up to 600°C. Processes stainless steel, carbon steel, non-ferrous metals, and composite materials with hardness up to HRC 35.
• [Vibration-Reduced Operation]：Five-flute geometry with spiral chip channels minimizes chatter during operation. 1/4" hex shank ensures secure grip in all standard chucks with ±0.1mm runout tolerance.
• [Comprehensive Size Range]：Six most-used sizes from 1/4" to 3/4" cover 90% of common applications. Laser-etched markings maintain permanent size identification despite heavy use.
• [Usage Advisory]：Apply cutting fluid when processing hardened metals. Maintain 1500-3000 RPM for optimal performance. Store in original case to prevent edge damage. Replace when cutting resistance increases significantly.
