Exactly what are solid carbide rotary burrs?

A rotary burr is a solid carbide cutting tool used for removing material coming from a work piece by rotating at high speeds, usually within a pneumatic air tool like a pencil grinder or maybe a milling machine or machining centre. They could be employed in different metalworking applications including deburring, stock removal, elimination of sharp edges counter sinking, shaping, grinding and opening up a dent. Most burrs are made 100% from solid carbide, however, some larger diameter burrs have a steel shank with a brazed carbide head. ATA Garryson burrs are produced from a combination of Tungsten Carbide and Cobalt. Cobalt will be the binder holding the carbide grains together. Harder than nearly all metals, the nation’s capability to be used at high speeds. It features a reduced likelihood of contamination and can be utilized on most materials.

What materials can solid carbide burrs provide on?

Carbide burrs can be utilized on all metals, including steel, metal, Inconel, aluminium, certain, hardened steel and titanium. They can also be used on plastic, rubber, graphite and fibre glass. Depending on the workpiece material, a specific cut type or coating may be required for optimal performance, for instance alu-cut burrs feature wider chip pockets as well as a single cut geometry to avoid the aluminium from clogging up the burr, or even a coated burr may be needed on heat resistant materials for example Inconel or metal.

How big carbide burrs can be purchased?

Our selection of burrs starts from just 1mm diameter and go all the way approximately 25mm diameter.

Exactly what is the benefit from a coated carbide burr?

Coated carbide burrs offer longer tool life compared to uncoated burrs, specially in metals which can be hard, heat resistant or abrasive.

Carbide Burr Cut Types Explained

The most typical type of carbide burr cut type can be a double cut burr, often known as a cross cut or diamond cut burr which are suited to the vast majority of applications. However, there are lots of other geometry burrs to choose from which may aid performance in various applications:

Single cut carbide burrs:

These have a single right-hand spiral flute and so are mostly used on ferrous materials for example cast iron or non ferrous materials including copper, brass and aluminium. They offer faster cutting with minimal developed edge, even so the disadvantage is because access in one direction therefore making them harder to use for the operator when compared to a double cut burr.

Double cut carbide burrs

The most popular and easy to make use of geometry for ferrous metals such as carbon and alloy steels or soft stainless steels. The feature right and left handed cutting angles (cross cut style) and can produce a good surface finish when compared with single cut burrs. A disadvantage of the double cut burr is built up edge of soft long chipping materials.

Aluminium cut (Alu-Cut) carbide burrs

Solid carbide burrs made for use on soft long chipping materials including aluminium, copper, brass and plastic. They feature sharp cutting edges and deep flute pockets, such as a milling cutter, which prevents built-up edge and enables large stock removal. The sharp cutting edges ensure a good surface finish.

Stainless cut (Inox-Cut) carbide burrs

It comes with a powerful grinding giving Thirty five percent more stock removal compared to conventional burr geometry and reduced heat build-up on the technologically advanced for optimum tool life.

Steel cut carbide burrs

A unique geometry double cut design specifically for high stock removal applications on carbon and alloy steels.

Single Cut vs Double Cut Carbide Rotary Burrs

Two of the most popular varieties of Carbide rotary burr are single cut and double cut.

The only cut, which is ideal for most ferrous metals, provides a faster cut with minimal clogging. The only cut includes a single right hand spiral flute.

The double cut, frequently used on hard metals to supply a finer, cleaner finish. The double cut has both right- and left-handed cutting angles.
