Product Overview
This is a cemented carbide rotary burr, also known as a high-speed assorted milling cutter or die milling cutter. It is used with handheld electric or pneumatic tools to perform finishing, deburring, chamfering, grooving, and polishing tasks on metal and non-metal materials. The burr is designed for precision work in mold cavities, casting cleanup, and internal surface finishing.
Key Benefits
- Processes all types of metal including hardened steel and non-metal materials such as marble, jade, and bone
- Longer service life than high-speed steel cutters and small grinding wheels
- High finish quality with consistent precision on mold cavities and internal surfaces
- No dust pollution compared to grinding wheels, improving workplace safety
- Reduces labor intensity and improves working conditions with simple, safe operation

Problems It Solves
- High-speed steel cutters wear out quickly when machining hardened steel or abrasive materials
- Grinding wheels produce dust, requiring ventilation and protective gear
- Manual finishing with files or sandpaper is slow and inconsistent for complex shapes
- Inconsistent surface finish leads to rework or rejection in precision parts
- Frequent tool changes increase downtime and processing cost
Who It Is For
- Mold and die shops requiring precision finishing of complex cavities
- Automotive and machinery manufacturers needing consistent deburring and chamfering
- Shipyard and foundry maintenance teams cleaning castings and welds
- Repair shops handling internal surface finishing and pipe cleaning
- Artisans and craft producers working with hard non-metal materials
Application Scenarios
- Finishing mold cavities in shoe molds and other metal dies
- Removing flash, burrs, and welds from cast, forged, and welded parts in automotive and shipbuilding factories
- Chamfering and grooving mechanical components in machine shops and repair workshops
- Polishing impeller passages in automobile engine manufacturing
- Craft carving and gift making using marble, jade, or bone
Technical Features
- Made from cemented tungsten carbide (WC-Co) with controlled cobalt content
- Available in multiple shapes and sizes for different applications
- Operates at 6000–50000 rpm with high-speed electric or pneumatic tools
- Fine grain structure ensures sharp cutting edges and high durability
- Consistent geometry from pressing and sintering for repeatable results
Materials and Grades
- WC-Co cemented carbide with cobalt content selected for hardness and toughness balance
- Lower cobalt grades like YG6 for wear resistance in clean abrasive applications
- Higher cobalt grades like YG15 for impact resistance in high-vibration environments
Customisation Options
- Manufactured to customer drawings including non-standard shapes and sizes
- Grade selected based on material being processed and service conditions
- Samples produced for pre-testing before bulk release
- Custom packaging available upon request

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
- Use only with tools operating between 6000–50000 rpm to avoid tool failure
- Select the grade based on the material: YG6 for clean abrasives, YG15 for impact-heavy tasks
- Apply light, consistent pressure to avoid overheating and premature wear
- Do not force the burr into hard spots; let the tool cut naturally
- Keep the tool clean and store it in a dry place to prevent damage
How It Compares With The Alternatives
| Alternative | Trade-off |
|---|---|
| High-speed steel cutter | HSS wears faster in hardened steel and abrasive materials; carbide lasts longer and maintains edge sharpness |
| Small grinding wheel | Grinding wheels produce dust, require ventilation, and wear unevenly; carbide burrs are dust-free and more durable |
| Ceramic burr | Ceramic is harder but more brittle; carbide tolerates impact and vibration better in handheld tools |
Tungsten Carbide Rotary Burr 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 make carbide burrs to my own drawing?
Yes. OEM and ODM to customer drawings is standard. We can produce non-standard shapes and sizes based on your specifications.
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 and load. Lower cobalt grades like YG6 offer better wear resistance in clean abrasive service; higher cobalt grades like YG15 handle impact and vibration better. Send the operating conditions and a grade will be recommended.
