Precisely what are solid carbide rotary burrs?

A rotary burr is a solid carbide cutting tool employed for removing material coming from a work piece by rotating at high speeds, usually in a pneumatic air tool such as a pencil grinder or possibly a milling machine or machining centre. They are often used in different metalworking applications such as deburring, stock removal, removal of sharp edges counter sinking, shaping, grinding and opening an opening. Most burrs are created 100% from solid carbide, although some people might larger diameter burrs come with a steel shank having a brazed carbide head. ATA Garryson burrs are made from a mixture of Tungsten Carbide and Cobalt. Cobalt could be the binder holding the carbide grains together. Harder than virtually all metals, the nation’s ability to be utilized at high speeds. It possesses a reduced chance of contamination and is used on most materials.


What materials can solid carbide burrs provide on?

Carbide burrs can be used on all metals, including steel, metal, Inconel, aluminium, iron, hardened steel and titanium. They could also be used on plastic, rubber, carbon fibre and fibre glass. Based on the workpiece material, a unique cut type or coating are usually necesary 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 perhaps a coated burr may be required on heat resistant materials including Inconel or stainless.

How big a carbide burrs are available?

Our range of burrs starts from just 1mm diameter and go all the way as much as 25mm diameter.

Exactly what is the benefit from a coated carbide burr?

Coated carbide burrs offer longer tool life in comparison with uncoated burrs, especially in metals that are hard, heat resistant or abrasive.

Carbide Burr Cut Types Explained

The most frequent type of carbide burr cut type is a double cut burr, also called a cross cut or diamond cut burr which can be suited to nearly all applications. However, there are several other geometry burrs from which to choose which might aid performance in numerous applications:

Single cut carbide burrs:

These come with a single right-hand spiral flute and are most often utilized on ferrous materials including surefire or non ferrous materials such as copper, brass and aluminium. They supply faster cutting with minimal piled up edge, however the disadvantage is they pull-up one way therefore driving them to harder for the operator compared to a double cut burr.

Double cut carbide burrs

The most popular and straightforward to use geometry for ferrous metals like carbon and alloy steels or soft stainless steels. The feature all over the place handed cutting angles (cross cut style) and can make a good surface finish in comparison with single cut burrs. A disadvantage of the double cut burr is made up regarding 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, similar to a milling cutter, which prevents built-up edge and allows for large stock removal. The sharp cutting edges ensure a fantastic surface finish.

Stainless cut (Inox-Cut) carbide burrs

It possesses a high performance grinding giving 35 % more stock removal compared to conventional burr geometry and reduced heat increase on the innovative for best tool life.

Steel cut carbide burrs

An exclusive 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 kinds of Carbide rotary burr are single cut and double cut.

The one cut, that’s ideal for most ferrous metals, gives a faster cut with minimal clogging. The single cut includes a single right hand spiral flute.

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