FAQ for tungsten carbide rods with coolant holes:
Q1: What are tungsten carbide rods with coolant holes?

A: Tungsten carbide rods with coolant holes, also known as internal coolant carbide blanks, are solid cemented carbide blanks with precision axial through holes. They are specially engineered for manufacturing coolant-fed cutting tools, including solid carbide drills, end mills, reamers, and boring bars. The coolant passages allow cutting fluid to reach the cutting edges directly, delivering effective cooling, lubrication, and efficient chip removal during high-precision and deep-hole machining operations.

 

Q2: What are the common coolant hole structures for tungsten carbide rods?

A: We supply three mainstream coolant hole configurations to match different tool designs and machining requirements:
Single straight hole: Ideal for standard carbide drills and short-flute end mills, a cost-effective choice for general machining applications.
Twin straight holes: Suitable for deep-hole drilling and high-feed milling, delivering balanced coolant flow and stable cutting performance.
Helical coolant holes (30°/40°/45°): Perfect for spiral flute cutters. The swirling coolant flow improves cooling efficiency and chip evacuation, enhancing tool stability and service life.
Custom hole diameters, offset holes, and multi-hole layouts are available upon request.

 

Q3: What cutting tools are manufactured from your coolant hole carbide rods?

A: Our precision coolant hole carbide blanks are widely used to produce internal-coolant solid carbide drills, deep hole drills, high-feed end mills, reamers, boring bars, and custom forming tools for the automotive, aerospace, mold, and precision machinery industries.

 

Q4: Can you customize grain size and cobalt content?

A: Yes. We support full OEM and ODM customization, including tailored cobalt content, grain size (0.2–3μm), and chemical composition to meet special machining requirements and specific tool performance targets.

 

Q5: Are your tungsten carbide rods with coolant holes cryogenically treated?

A: Yes, cryogenic treatment is included as standard for all our tungsten carbide rods with coolant holes, with no extra charge for standard specifications.
This controlled deep-freeze process relieves residual sintering stress, stabilizes the cobalt binder phase and refines the carbide microstructure. For internal coolant carbide blanks, it improves wear resistance and dimensional stability, and reduces microcracking risk at coolant hole edges during tool grinding and heavy-duty machining.
It extends the service life of finished coolant-fed carbide tools such as deep hole drills, high-feed end mills and precision reamers. Custom treatment parameters for special carbide grades are available upon request.

 

Q6: What standard sizes are available from stock?

A: Our standard stock outer diameter ranges from 3mm to 32mm, with standard lengths of 100mm, 150mm, 200mm, and 330mm. The coolant hole inner diameter ranges from 1.0mm to 6mm, proportionally matched to the rod outer diameter. All stock rods are precision ground to h6 tolerance and a mirror surface finish.

 

Q7: Do you support non-standard custom specifications?

A: Absolutely. As an experienced manufacturer of tungsten carbide rods with coolant holes, we offer full one-stop customization services, including special outer diameters, custom lengths, offset holes, three-hole layouts, custom helix angles, double-end chamfers, flat surfaces, and step rods. You can send us your technical drawings for an accurate quotation and tailored production planning.

 

Q8: What is your minimum order quantity (MOQ) for tungsten carbide rods with coolant holes?

A: The MOQ for standard in-stock carbide rods is 10 pieces. The MOQ for non-standard customized products is 50–100 pieces, depending on product complexity.

 

Q9: What is your lead time?

A: In-stock items can be shipped within 2–3 days. New non-standard customized orders take 15–30 working days, subject to processing complexity.
