These carbide rods with two helical coolant holes are manufactured using advanced deep-hole drilling technology and feature a 30° helical angle design. Developed specifically for the European and North American markets, they address the limitations of traditional straight-hole rods by significantly improving coolant flow and chip evacuation, thereby enhancing tool life and machining efficiency.

Product Features:

• Dual Helical Coolant Channels
The 30° spiral angle creates a vortex effect, increasing coolant coverage by over 50% compared to straight-hole designs. This ensures better thermal control during high-speed operations.

• Enhanced Chip Evacuation
The helical coolant paths generate a negative-pressure suction effect that effectively removes chips from the cutting zone, minimizing clogging and tool wear.

• Precision Hole Geometry
The position and diameter of the coolant holes are tightly controlled, ensuring uniform coolant distribution throughout the carbide steel rod and maximizing cutting stability.

• Optimized for Deep Hole Machining
Purpose-built for deep-hole drilling and extended-reach milling applications, these carbide rods with two helical coolant holes deliver consistent performance even under demanding conditions.

• High-Pressure Resistant Design
Special treatment of the internal hole walls ensures the carbide steel rod maintains structural integrity under high-pressure coolant delivery, preventing deformation or cracking.

• Reliable Mass Production
A mature and refined manufacturing process guarantees stable, high-volume output with consistent quality, making these rods ideal for industrial-scale tool production.

Applications:

• Deep Hole Drill Manufacturing
Ideal for producing deep hole drills ranging from φ3mm to φ20mm. The dual helical coolant channels significantly improve chip evacuation and heat dissipation during high-performance drilling.

• Long-Flute End Mills
Designed for end mills with cutting length-to-diameter ratios over 4:1. These carbide rods with two helical coolant holes ensure uniform cooling along the entire cutting edge, solving the uneven coolant distribution often seen with traditional rods.

• Automotive Engine Machining
Specialized for machining deep holes in engine blocks and similar components. The enhanced coolant flow and reliability of the carbide steel rod meet the needs of efficient, high-volume production environments.

• Aerospace Structural Part Machining
Suitable for deep-hole processing of titanium and nickel-based alloys. The improved cooling performance helps extend tool life under the extreme demands of aerospace materials.

• Mold Cavity Finishing
Used in the production of finishing tools for deep-cavity mold machining. The stable coolant supply through the helical holes helps achieve superior surface finish and dimensional precision.
