• High hardness, wear resistance, and intensity; anti-bending
• Symmetrical cutting blades help with high-effective cutting, avoiding drilling offset.
• Sharp cutting edge, reduce cutting force, lower breaking rate, and improve the quality of the hole wall.
• Precision machining by high-accurate equipment, with good milling and cutting performance, ensures high efficiency.
• To remove chips with big space and small resistance, smooth chip removal, less heating value, and to reduce pollution
