Product Overview
This is a tungsten carbide rod with two 30º twisted coolant ducts, designed for use in cutting tools such as drills, end mills, and reamers. The internal ducts provide efficient chip removal and cooling during high-speed machining. The rod is available in various diameters and lengths, with ground or unground finishes. It is made from virgin tungsten carbide material to ensure consistent wear resistance and impact strength.
Key Benefits
- Internal coolant ducts reduce heat buildup during machining, extending tool life
- Twisted ducts improve coolant flow and chip evacuation in deep holes
- Virgin tungsten carbide material ensures consistent hardness and toughness
- Available in multiple sizes and lengths to match tool design requirements
- Ground finish (h6) reduces need for additional grinding, lowering processing cost
Technical Data
Values below come from the product data we publish. Anything not listed is confirmed against your drawing at quotation.

Problems It Solves
- Heat buildup in deep holes causes premature tool failure in stainless steel and nickel alloys
- Chip clogging in narrow flutes leads to poor surface finish and tool breakage
- Inconsistent material quality in blanks results in variable tool performance
- High grinding allowance on unground rods increases processing cost and lead time
- Lack of coolant channels in standard rods reduces tool life in continuous machining
Who It Is For
- Tool manufacturers producing drills, end mills, and reamers
- Mold and die shops requiring high-precision carbide rods for core pins
- Machine tool builders sourcing raw blanks for custom cutting tools
- Industrial equipment makers developing hole-drilling tools for nonferrous metals
- Contract manufacturers producing carbide tools under OEM or ODM terms
Application Scenarios
- Drill bits for aluminum alloy and cast iron where chip clogging is a concern
- End mills for stainless steel and nickel-based alloys requiring effective cooling
- Reamers for refractory alloy steel where heat accumulation causes edge wear
- Core pins and mold punches in high-speed forming operations with tight tolerances
- PCB drilling tools where consistent coolant delivery prevents tool failure
Technical Features
- Two 30º twisted coolant ducts for improved coolant delivery and chip removal
- Available in multiple diameters and lengths to match tool design
- Ground finish (h6) for reduced machining time and tighter tolerance control
- Virgin tungsten carbide material used for consistent physical properties
- Standard pitch and duct dimensions provided in the specification table
Materials and Grades
- 100% virgin tungsten carbide for consistent grain structure and mechanical properties
- Cobalt content adjusted by grade to balance hardness and toughness
- Lower cobalt grades (e.g. YG6) for wear resistance in clean abrasive materials
- Higher cobalt grades (e.g. YG15X) for impact resistance in shock-prone operations
Customisation Options
- Manufactured to customer drawings including non-standard sizes and duct configurations
- Grade selected based on the material being machined and service conditions
- Custom finish (e.g. h6, H6, h5) available on request
- Samples produced for pre-testing before bulk release
- Multiple duct types and pitch variations available upon request

Dimensional and physical property inspection
Packing and shipping
Quality Control
- Physical properties, shape and tolerance are checked before shipping
- Every order is tested before bulk production is released
- Inspection photographs of the finished order are sent for confirmation before delivery
Use Guide
- Specify the material to be machined, cutting speed, and depth of cut when requesting a quote
- Use higher cobalt grades (e.g. YG15X) for applications with impact or vibration
- Ensure ducts are not blocked during grinding or assembly to maintain coolant flow
- Match duct pitch and diameter to the tool design to avoid flow restriction
- Keep a sample from the first batch for comparison in future orders
How It Compares With The Alternatives
| Alternative | Trade-off |
|---|---|
| Solid carbide rod without coolant ducts | No internal cooling reduces tool life in high-speed or deep-hole machining; ducts improve chip removal and heat dissipation |
| Steel rod with coolant channels | Steel wears quickly in abrasive materials; carbide maintains edge integrity over longer runs |
| Ceramic rod with ducts | Ceramic is brittle and prone to chipping under impact; carbide tolerates shock better in interrupted cutting |
Two 30º Twisted Coolant Ducts Rod FAQ
Are you a trade company or a manufacturer?
A manufacturer. The company has produced tungsten carbide parts for over 15 years and takes on design and processing of carbide products with technical support.
Where is your factory located?
Zhuzhou City, Hunan Province, China, which is the country's tungsten carbide production base.
Can you produce the products according to my own drawing?
Yes. OEM and ODM to customer drawings is standard for this product, including non-standard sizes and duct configurations.
Can I get a sample before placing a bulk order?
Yes. Samples are available for pre-testing. Send the drawing and service conditions and a sample can be quoted.
How long does an order take?
Stock items are shipped 3-5 days after payment is received. Customised items are given a delivery time in the quotation.
How do I know the parts were checked before they shipped?
Physical properties, shape and tolerance are inspected before shipping, and detailed inspection photographs of the order are sent for confirmation before delivery.
Which grade should I choose?
It depends on the material being machined. Lower cobalt grades such as YG6 offer better wear resistance in clean abrasive materials; higher cobalt grades such as YG15X tolerate impact better in shock-prone operations. Send the service conditions and a grade will be recommended.
