Product Description
★
Basic info.
1. The tungsten solid carbide rods is press molded by molding or extrusion.
2. The tungsten solid carbide rods is sintered by a low-pressure sintering integrated furnace, thus the overall performance is high.
3. The rough tungsten-cobalt carbide round bar, or the outer diameter of the round bar can be refined and polished according to any tolerance. The common tolerances are h5,h6, -0.005, etc., and the carbide rods end chamfer can also be processed.
4. Carbide rods is suitable for the processing of general steel, cast iron, stainless steel, heat resistant steel, nickel base and titanium alloy. Recommended for general purpose carbide tool materials such as twist drills, end mills, taps, and gun drills.

Frequently Asked Questions
Q What manufacturing processes are used for your tungsten solid carbide rods?
The rods are press-molded through specialized molding or extrusion techniques and subsequently sintered using an advanced low-pressure sintering integrated furnace to ensure high performance and structural integrity.
Q What custom tolerances can be achieved on the outer diameter?
We can refine and polish the outer diameter to match precision customer tolerances, commonly achieving h5, h6, and -0.005 mm limits, alongside custom end chamfering.
Q Which materials are best suited for cutting tools made from these carbide rods?
Our carbide rods are engineered for processing general steel, cast iron, stainless steel, heat-resistant alloys, nickel-based metals, and titanium alloys, making them ideal for twist drills, end mills, and reamers.
Q Are coolant hole configurations available for advanced drilling operations?
Yes, we provide standard carbide rods featuring either one straight coolant hole or two straight coolant holes in various outer diameters and internal hole dimensions.
Q How do you ensure product quality and safe international transit?
Every batch undergoes rigorous checks via our dedicated Quality Control Center, from raw materials to post-finish inspection. Finished items are safeguarded in specially designed packing boxes and protective tubes suitable for air, sea, or express delivery.
