Engineered with a 40° spiral angle, our two helix holes carbide rod is developed specifically for the high-performance machining demands of the European and North American markets. Compared to traditional 30° designs, this structure improves coolant flow rate by 25%, effectively addressing the heat dissipation challenges of high-speed cutting and difficult-to-machine materials—significantly extending tool life.

Product Features:

• Optimized 40° Spiral Angle
Refined through hydrodynamic simulations, the 40° angle enhances coolant velocity and promotes vortex formation for more efficient cooling—an essential feature in any carbide rod with coolant hole.

• High-Efficiency Heat Dissipation
The dual-channel spiral design creates forced convection within the rod, efficiently lowering the temperature in the cutting zone—making this two helix holes carbide rod ideal for demanding thermal conditions.

•Enhanced Chip Evacuation
The steep spiral generates stronger negative pressure suction, enabling rapid chip removal and reducing the risk of secondary cutting or surface damage.

• Optimized for High-Speed Machining
Tailored for modern CNC operations, this carbide rod with coolant hole supports stable, high-RPM cutting while maintaining accuracy and tool integrity.

• Wear-Resistant Construction
Internal coolant passages are surface-treated to resist wear and deformation, ensuring long-term dimensional stability and reliable performance.

•Precision Manufacturing Process
Produced using advanced deep-hole drilling and spiral milling techniques, each rod guarantees consistent helix angle and hole diameter precision across all batches.
