Hard materials can be cut, shaped, ground, and chamfered using tools called carbide burrs. Different carbide burr cuts will work well with various materials.
Air tools like die grinders, pneumatic rotary tools, high-speed engravers, Micro Motors, Pendant Drills, Flexible Shafts, and hobby rotary tools like a Dremel all make use of carbide burs.
Below we have mentioned 6 tips you must know about carbide burr.
Carbide Burrs Can be Used on Many Materials
Die grinder bits can be used on a wide range of materials, including acrylic, fiberglass, plastic, all types of wood, steel, aluminum, and cast iron. Additionally ideal for working on softer metals like gold, platinum, and silver, carbide burrs last a very long time without cracking or fracturing.
Who Uses Carbide Burrs?
Metalworking, tool building, engineering, model engineering, wood carving, jewellery making, welding, chamfering, casting, deburring, grinding, cylinder head porting, and sculpting all make extensive use of carbide burrs.
The aerospace, automotive, dental, metal sculpting, and metal smithing industries are just a few that use them.
There are typically two cuts of carbide burrs: single cut and double cut
Right-handed (Up cut) spiral flutes are present in single cut (one flute) carbide burrs. These are frequently used with ferrous metals, stainless steel, hardened steel, copper, and cast iron, and they remove debris swiftly. Use for milling, deburring, cleaning, and removing heavy stock.
The Different Shapes of Carbide Burrs and Their Use
What profile or cut you want to create will determine what shape you should employ. These variously shaped burs will fit into numerous crevices and provide some eye-catching profiles.
Carbide Ball Burrs
To cut your material concavely or to shape and hollow out a space, use a ball- or spherical-shaped carbide burr. For intricate carving jobs, little carbide ball burrs as small as 0.5mm in diameter are appropriate. These carbide carving burrs are frequently used in a hobby drill, a micro motor, or a high speed handpiece by wood carvers, stone carvers, and metal engravers. Use a handpiece that runs true, that is, without wobble, as we previously advised.
Carbide Tree Burrs
Use to create concave cuts and to round off edges. For cutting in difficult-to-reach places and along acute angled curves, use the pointed end.
4 What Speed or RPM should you use your Carbide Burrs?
It’s reasonable to say that you shouldn’t need to go faster than 35,000 RPM when using a carbide burr in a rotary tool or die grinder, but the speed you use will depend on the material you’re using it on and the contour you’re producing.
Important information: If the burs are chipping readily, it may be because the speed is too slow. It’s best to begin the cutting slowly and pick up speed as you go, though. High speeds will avoid clogging in your burrs’ flutes.
Don’t exert excessive pressure
As with all drill bits and burrs, let the burr do the work and exert little pressure; otherwise, the flutes’ cutting edges will chip off or smooth out too rapidly, shortening the burr’s lifespan.
Carbide Burrs are Harder than HSS Burrs
Good calibre Machines are used to machine-grind a specific grade of carbide into carbide burrs. Tungsten Carbide can be utilised on far more difficult applications than HSS because of its exceptional toughness (High Speed Steel).
You can run carbide burrs hotter and longer than HSS because they work better at higher temperatures. Carbide is usually a better option for long-term performance because HSS burrs will start to soften at higher temperatures.
