Carbide burr are tools used to remove material. To be more specific, they are used for deburring, cleaning, finishing, smoothing, shaping, and carving many types of materials. Basically, the very high-speed carbide bur operates at makes it easy to shape the material it comes in contact with. Carbide burs come in different types based on the jobs can do. Hence the type of carbide you need largely depends on what you want to use it for.
In this article, we will talk about a type of carbide burr called the Aluma cut carbide burrs and tips on how to use it effectively.
Aluma Cut Carbide burrs is a special kind of carbide burr designed to clean a wide range of materials including wood, plastics, stainless steel, and other metals. It is an abrasive tool that helps remove materials in plastic, wood, metals and steel.
Aluma Cut Carbide burrs can also work on soft metals like brass, aluminium, other non-ferrous metals and non-brittle plastics. Carbide burrs come with open face aids; this indicates that swarf removal is easy on non-ferrous metals. They have a geometry designed to remove stock from non-ferrous and plastic materials.
Where Do You Put Aluma Cut Carbide Burrs?
Aluma carbide burrs are used in Air Tools, Die grinders, Micro Motors, Pneumatic rotary tools and high-speed engravers, Flexible Shafts, hobby rotary tools and Pendant Drills such as a Dremel.
Who Uses Aluma Cut Carbide Burrs?
Aluma Cut Carbide burrs are used in metalwork, engineering, toolmaking, wood carving, welding, deburring, grinding, sculpting, jewellery making and casting. Hence they are used in most industries including automotive, aerospace, metal making and dental industries.

Advantages of Carbide Burrs Aluminum Cut
- It is very efficient in removing stock.
- They have large chips
- Material adhesion is low.
- Extremely long tool life
- It can get to speeds as high as 1,100 m/min
- It is sharper and this is what makes it efficient.
- They cut cleaner than the rest. A clean-cut allows wood joints to glue better and tighter.
- They are suited for milling
- They have a controlled cutting action
- Highly-improved surface finish
- It has a high performance.
Tips of Carbide Burrs Aluminium Cut
Here are some useful tips that can guide you on how to use Carbide Burrs Aluminium cut effectively.
1. Run Them At Very High Speed.
This reduces tooth loading and this in turn, helps to minimise chipping while increasing the tooth life. The burrs must be kept running at high speeds in die grinders. Pistol drills should be avoided as they are quite slow and will cause the burr to chirp and chatter. Hence to maximize the effect of burrs, you need to use it with high rotational speeds
2. Apply Constant Pressure And Move It In A Clockwise Direction.
The carbide burr aluminium cut has to contact the job from a right to left direction. Do not add excessive pressure as it can cause tooth loading or damage. Light pressure also helps to prevent overheating. You should keep only 30% of the burr’s circumference with the job. A contact of over 30% will only cause damage and reduce the life of your burr.
3. Both sides of the burr must not contact at the same time.
There is a higher chance that the burr gets jammed or chipped if you use both sides to contact the job at a time. Also, note that burrs must not contact hard materials when not in motion. Doing this will damage the tooth of the burr. Even dropping the burr on a steel or concrete surface will make them chip.
4. Always use Drives with Elastic Mounted Spindle
Use your burrs on powerful drives that come with elastically mounted spindles. The elastic spindles help to avoid unnecessary vibration.
5. Signs of Misuse
a. There are times the head comes off the shaft. Overheating and excessive pressure is responsible for this.
Signs include:
- Melted brazing
- Colour change of Tungsten head to yellow/black/blue
b. Burr jammed in a hole.
- Marks present on the shank
- The tooth is chipped
c. Burr is chipped probably due to burr being dropped.
Signs include:
- No other damage to the burr
- plenty of little chipping at the end of the burr
- Lots of residues in the burr teeth.
d. Burr runs slowly
Signs include:
- Chipping of burr
6. You Can Use Carbide Burrs Aluminium Cut on Many Materials
The Carbide Burrs Aluminium Cut tool works on lots of materials: metals including aluminium, cast iron, plastic, acrylics and fibreglass. They can also work on soft metals like gold, platinum and silver as they have a long tool life devoid of chipping or breaking.
- Cast Iron
- Bronze
- Copper
- Titanium alloys
- Aluminium
- Titanium
- Thermoplastics
- Fibreglass
- Plastic, Carbon Fiber Reinforced Plastic (CRP), Glass Fibre Reinforced Plastic (GRP)
- Brass, Copper & Bronze
- Zinc
- Wood
7. Carbide Aluminium Cut Burrs are Harder than HSS Burrs
Quality carbide aluminium cut burrs are usually very hard especially due to the hardness of Tungsten carbide where they are made from. For this reason, they can be used on jobs stronger than HSS (High-Speed Steel).
They can also perform at very high temperatures than HSS. You can use them in hotter temperatures for a long time. Unlike the HSS burrs that starts to soften when temperatures get high, carbide does not do well long term.
8. Start With Low Speeds
The effective speed of the burr is usually dependent on 3 factors
- The type of die grinder used.
- The size of the bur.
- The material removed.
The speed used in your rotary tool is dependent on the material you are applying it on and the shape being produced. However, you should not go more than 35,000 RPM. A chipping burr is a sign of slow speed. Hence it is advisable to start at a lower speed and gradually increase to a speed that will give the most effective results. High speeds also prevent your carbide burrs flutes from clogging.
9. Make Sure The Bur Is Inserted And Fitted Into The Collect.
It is important to note that when placing the carbide burr aluminium cut into the air motor, it should be inserted and well fitted into the collet. Do this in a bid to reduce overhang. The bur should touch the cut lightly as this helps to avoid digging into the material.
10. Use Lubricants To Prevent Loading
When using Carbide burr Aluminum cut in magnesium and aluminium, you should consider using a lubricant, tallow or wax. Doing this will help prevent the flutes from packing or loading.
Also, remember to follow these safety tips when using your Carbide Burr Aluminium Cut:
- Make sure you insert your burr shank into its collet and clamp it tightly.
- Wear a glove
- Do not snag or jam your burr into your job
- You should wear eye protection or for better face protection, wear a full face shield
Conclusion
With the above tips, I hope you are now better informed on how you should use your carbide burrs Aluminium cut, why you should use them and what you can use them on.
