What is a Carbide Burr?

A carbide burr is a rotating tool made of tungsten carbide, a hard material that's resistant to wear and high temperatures. These tools are used for cutting, shaping, grinding, and removing sharp edges or excess material from various substances, including metal, wood, plastic, and ceramics.

Choosing the Best Carbide Burrs Set

Material Quality

The material of the carbide burr is crucial for its performance and durability. Look for sets that feature high-quality tungsten carbide. This material is incredibly hard, resistant to wear, and can withstand high temperatures, making it ideal for heavy-duty applications.

Burr Shape

Different shapes of burrs serve different purposes:

  • Cylinder burrs are perfect for removing flat surfaces and contouring.
  • Ball burrs are ideal for round edge removal and creating concave cuts.
  • Tree burrs are used for rounding edges and making concave cuts in inaccessible places.
  • Flame burrs work well for contouring and round edge removal.
  • Cone burrs are used to smooth and shape hard-to-reach areas.

A set with a variety of shapes will provide greater versatility for different projects.

Cutting Edge

The cut of the burr refers to the pattern of the grooves or teeth on the burr's surface. There are primarily two types: single cut and double cut:

  • Single cut burrs have right-hand spiral flutes, suitable for use with ferrous and non-ferrous metals, producing long chips.
  • Double cut burrs have left and right-hand flutes, ideal for machining softer materials like aluminium or plastic, producing smaller chips and a smoother finish.

Shank Size

The shank size refers to the diameter of the burr's stem, which is inserted into the power tool. Common sizes are 1/8 inch and 1/4 inch. Ensure the shank size of the burr matches the collet size of your power tool.

Number of Pieces

The number of pieces in the set impacts its versatility. More pieces usually mean a variety of shapes and sizes, which can be beneficial for tackling different tasks.

What can our Carbide Burr Tools be used for?

Our carbide burrs are used in air tools such as die grinders, pneumatic rotary tools and high speed engravers. Micro Motors, Pendant Drills, Flexible Shafts, and hobby rotary tools such as a Dremel.

Carbide burrs are widely used for metalworking, tool making, engineering, model engineering, wood carving, jewelry making, welding, chamferring, casting, deburring, grinding, cylinder head porting and sculpting. Carbide burrs are used in the aerospace, automotive, dentistry, stone and metalsmith industries.

What Carbide Burr Tool RPM speed should you use?

The speed at which you use your carbide burr in your rotary tool will depend on the material you’re using it on and the contour being produced but it’s safe to say you do not need more than 35,000 RPM. If the burs are chipping easily this could be due to the speed being too slow. It’s ideal to start the bur off slow, increasing the speed as you go along. High speeds will prevent clogging in the flutes of your carbide burs.

As with all drill bits and burrs, let the burr do the work and apply only a little pressure, otherwise the cutting edges of the flutes will chip away or become smooth too quickly, reducing the life of your burr.

Our carbide burrs we manufacture are machine ground from a specially chosen grade of carbide. Due to the extreme hardness of the tungsten carbide, they can be used on much more demanding jobs than HSS (High Speed Steel). Carbide Burrs also perform better at higher temperatures than HSS, so you can run them hotter, and for longer. HSS burrs will start to soften at higher temperatures, so carbide is always a better choice for long term performance.

Double the Cut, Double your Output

Designed to work as long as you do, M3Tools double-cut carbide burrs withstand the most demanding production runs due to the hardness of their tungsten carbide substrate, plus their stronger tooth formulation. Get ready to achieve better stock removal and granular chip break when you pair these carbide burrs with our Norton pneumatic die grinder or use them in your automated CNC machine.

What Are The Advantages of Tungsten Carbide Burrs?

  • Long life
  • Use for long production runs
  • High stock removal
  • Ideal for using on many hard and tough materials
  • Ideal for Deburring, finishing, carving, shaping and smoothing welds, moulds, dies and forgings

Carbide Tipped vs. Solid Carbide

When choosing the right carbide cutting tools, you can either pick between those that are tipped in the substance (either tungsten or titanium), or you can get a tool that is made entirely of this material.

For our money, we believe that carbide tipped cutting tools are much better overall. The reason for this is that these tools still use steel for the core components, which is stronger and more reliable than solid carbide.

The issue with solid carbide tools is that they are prone to fracturing. While the metal is resilient and keeps a clean cutting edge (more on that later), when it’s all there is, it loses a lot of its strength. Overall, you can get a lot more mileage out of tools with carbide tips, making them the better choice for most manufacturers.
