What exactly are solid carbide rotary burrs?

A rotary burr is really a solid carbide cutting tool employed for removing material from your work piece by rotating at high speeds, usually in the pneumatic air tool like a pencil grinder or even a milling machine or machining centre. They can be used in different metalworking applications for example deburring, stock removal, elimination of sharp edges counter sinking, shaping, grinding and examining a hole. Most burrs are produced 100% from solid carbide, however, some larger diameter burrs feature a steel shank with 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 just about all metals, the power to be applied out high speeds. It possesses a reduced risk of contamination and can be utilized on most materials.


What materials can solid carbide burrs be used on?

Carbide burrs can be utilized on all metals, including steel, metal, Inconel, aluminium, cast iron, hardened steel and titanium. They doubles on plastic, rubber, carbon fibre and fibre glass. Based on the workpiece material, a particular cut type or coating may be required for optimal performance, for instance alu-cut burrs feature wider chip pockets plus a single cut geometry to avoid the aluminium from obstructing the burr, or even a coated burr may be required on heat resistant materials such as Inconel or metal.

The size of carbide burrs can be obtained?

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

What’s the good thing about 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 commonest form of carbide burr cut type can be a double cut burr, often known as a cross cut or diamond cut burr which are suitable for most applications. However, there are many other geometry burrs from which to choose which might aid performance in several applications:

Single cut carbide burrs:

These include a single right hand spiral flute and therefore are normally suited for ferrous materials such as cast iron or non ferrous materials for example copper, brass and aluminium. They feature faster cutting with minimal accumulated edge, nevertheless the disadvantage is that they access one way therefore causing them to be harder to use for the operator than a double cut burr.

Double cut carbide burrs

The most popular as well as simple to use geometry for ferrous metals such as carbon and alloy steels or soft stainless steels. The feature nearly everywhere handed cutting angles (cross cut style) and are able to develop a good surface finish in comparison to single cut burrs. A problem with the double cut burr is created up regarding soft long chipping materials.

Aluminium cut (Alu-Cut) carbide burrs

Solid carbide burrs created 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 good surface finish.

Stainless-steel cut (Inox-Cut) carbide burrs

It comes with a top rated grinding giving Thirty five percent more stock removal when compared with conventional burr geometry and reduced heat increase in the innovative for max tool life.

Steel cut carbide burrs

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

Single Cut vs Double Cut Carbide Rotary Burrs

The two most popular varieties of Carbide rotary burr are single cut and double cut.

The single cut, which can be ideal for most ferrous metals, supplies a faster cut with minimal clogging. The one cut features a single right-hand spiral flute.

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