The Double Straight Holes Rod features a symmetrical through-hole cooling design, developed specifically for the balanced cutting tool market in Europe and North America. Compared to single-hole designs, this carbide rod with two straight holes improves cooling uniformity by up to 50%, effectively addressing thermal deformation and uneven tool life caused by off-center coolant flow.
Product Features:
• Symmetrical Cooling Layout
Two holes placed 180° apart eliminate thermal stress and deformation from one-sided cooling.
• Balanced Heat Dissipation
Dual channels deliver coolant evenly, ensuring uniform temperature across the tool section.
• Structural Strength Optimization
Symmetry maintains rod balance, preventing structural weakening from eccentric design.
• Standardized Manufacturing
Mature straight-hole technology ensures consistent quality in batch production.
• Cost Efficiency
Easier to process than spiral holes, the two straight holes carbide rod offers both performance and economy.
• Easy Maintenance
The straight-through structure allows for easy cleaning and unclogging, minimizing production downtime.
