Carbide Steel Rods With Two Helical Coolant Holes are manufactured using 30° spiral angle deep hole technology, specifically designed for the European and American deep hole drill bit and long blade tool markets. The spiral channels create a vortex cooling effect, significantly improving chip evacuation efficiency and heat dissipation performance, resolving the issues of uneven cooling and blockages in traditional straight holes and extending tool life.

Triple-helical cooling hole cemented carbide bars feature a three-channel design with a 30° helix angle, specifically engineered for the North American large-diameter deep hole cutting tool market. The 120° equidistant layout enables 360° full-coverage cooling, delivering 40% higher efficiency than dual-channel designs and resolving insufficient heat dissipation issues in heavy-duty deep hole machining for the aerospace and automotive industries.

The 40° two helix holes carbide rod features an optimized spiral angle design, specifically engineered for high-speed cutting and machining of difficult materials. Compared to traditional 30° configurations, it increases coolant flow rate by 25%, effectively addressing heat dissipation challenges when processing titanium alloys, stainless steel, and other heat-sensitive materials. This enhanced cooling performance significantly extends tool life, making the carbide rod with coolant hole an ideal solution for modern high-efficiency machining applications.

The 40° carbide rod with three helix holes features a triple-channel helical design tailored for heavy-duty deep-hole machining. Compared to traditional two-hole designs, this three helix holes carbide rod offers a 60% improvement in heat dissipation efficiency. Its 120° evenly spaced layout ensures comprehensive cooling coverage, effectively addressing overheating issues during high-speed machining of large-diameter tools. Engineered to meet the demanding requirements of industries such as oil drilling and nuclear power equipment manufacturing, these carbide helical coolant hole rods deliver stable performance under extreme conditions. As part of our wholesale carbide helix rods offering, they provide reliable solutions for high-performance industrial applications.

The Single Straight Central Hole Rod is designed with a central through-hole for basic cooling, tailored to the needs of cost-sensitive, traditional cutting tool production. Compared to spiral-hole designs, this structure reduces manufacturing costs by up to 30%.With standardized hole sizes, the carbide rod with one straight hole meets the essential cooling requirements of drills, end mills, and other general purpose carbide rods, making it ideal for high-volume, economical production.

The Double Straight Holes Rod uses a 180° symmetrical cooling design, improving cooling uniformity by 50% over single-hole rods. This carbide rod with two straight holes minimizes thermal deformation and lowers production costs, making the two straight holes carbide rod ideal for end mills and drills. As a reliable carbide rod manufacturer, we ensure consistent quality and performance.
