Carbide burrs are rotary cutting tools used for shaping, grinding, and removing material. Here are 12 different shapes of carbide burrs:

1. Cylinder: Cylinder carbide burrs have a cylindrical shape and are used for shaping and contouring edges and surfaces.

2. Ball: Ball carbide burrs have a rounded shape and are used for grinding and shaping concave surfaces, such as holes and grooves.

3. Cone: Cone carbide burrs have a conical shape and are used for deburring and chamfering edges, as well as grinding and shaping internal surfaces.

4. Flame: Flame carbide burrs have a flame-like shape and are used for shaping and grinding curved surfaces, such as contours and fillets.

5. Tree: Tree carbide burrs have a tree-like shape and are used for shaping and grinding irregular surfaces, such as channels and curved edges.

6. Inverted Cone: Inverted cone carbide burrs have a conical shape that is inverted, with the wider end at the tip. They are used for grinding and shaping inside surfaces, such as holes and cavities.

7. Oval: Oval carbide burrs have an oval shape and are used for grinding and shaping curved surfaces, such as contours and fillets.

8. Taper: Taper carbide burrs have a tapered shape and are used for deburring and chamfering edges, as well as grinding and shaping internal surfaces.

9. Egg: Egg-shaped carbide burrs have an oval shape with a rounded end and are used for grinding and shaping concave and convex surfaces.

10. Double Cut: Double cut carbide burrs have two sets of teeth that cut in opposite directions, producing a finer finish. They are used for deburring, shaping, and finishing.

11. Diamond Cut: Diamond cut carbide burrs have diamond-shaped teeth that cut aggressively and are used for grinding and shaping hard materials, such as glass and ceramics.

12. Chip Breaker: Chip breaker carbide burrs have a unique shape with wavy teeth that break up material and prevent clogging. They are used for grinding and shaping soft materials, such as aluminum and brass.

When selecting the best carbide burr for your project, it is important to consider the shape of the burr, the size of the burr required, the type of material you will be working with, and the type of cut you need to make. By selecting the right carbide burr for the job, you can achieve precise and professional results.
