Inverted Cone Carbide Bur Standard Double Cut Carbide Rotary Bits 1/2IN

What is the function of rotating burrs?
Rotating burrs are rotating tools used to remove material. They are designed to rotate at extremely high speeds, allowing them to manipulate the material being processed. When using metal, burrs are very suitable for deburring, shaping and enlarging holes. Tungsten carbide rotary files can be used on all metals, including steel, stainless steel and aluminum. Metal manufacturers and engineers usually use them for tool manufacturing, model engineering, jewelry manufacturing, welding, deburring, grinding and engraving.

Tungsten carbide and high-speed steel
Generally, metal burrs are made of tungsten carbide or high-strength steel (HSS). When working with metals, tungsten carbide burrs are preferred. Due to their extremely high hardness, they can be used for more demanding jobs and will not wear out, unlike HSS. More importantly, HSS has lower heat resistance and will begin to soften at high temperatures. Tungsten carbide burrs will last longer and perform better at higher temperatures.

Why do we recommend tungsten carbide burrs?
High removal rate
Very suitable for deburring, shaping, welding leveling, expanding holes, engraving and finishing
Last longer
Performing in the heat
Ideal for all metals
Where tungsten carbide burrs can be used on any metal, there are different cutting methods suitable for different metals, please see below.

Cutting type
Metal burrs can be single/aluminum cutting or double/diamond cutting. The large single/aluminum cutting carbide file has a single right-cut spiral groove and can be used with cast iron, steel, copper, brass and other iron materials (such as aluminum). Single-edged burrs can provide faster cutting speeds without clogging (aluminum is often clogged), but their polishing effect is not as good as double-edged carbide burrs. Double/diamond cutting has left and right cutting functions, which can provide faster and more refined processing results. These are usually used for steel, stainless steel and other hard metals.
