Precisely what are solid carbide rotary burrs?

A rotary burr can be a solid carbide cutting tool useful for removing material from the work piece by rotating at high speeds, usually in a pneumatic air tool for instance a pencil grinder or perhaps a milling machine or machining centre. They could be used in different metalworking applications including deburring, stock removal, removing sharp edges counter sinking, shaping, grinding and examining an opening. Most burrs are made 100% from solid carbide, although some people might larger diameter burrs include a steel shank having a brazed carbide head. ATA Garryson burrs are produced 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 nation’s capacity to be applied out high speeds. It possesses a reduced likelihood of contamination and could be utilized on most materials.

What materials can solid carbide burrs be utilized on?

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

How big carbide burrs are available?

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

Exactly what is the advantage of a coated carbide burr?

Coated carbide burrs offer longer tool life when compared with uncoated burrs, particularly 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 that are ideal for the vast majority of applications. However, there are lots of other geometry burrs to select from which can aid performance in various applications:

Single cut carbide burrs:

These include a single right hand spiral flute and so are most commonly used on ferrous materials for example surefire or non ferrous materials like copper, brass and aluminium. They feature faster cutting with minimal developed edge, even so the disadvantage is that they pullup one way therefore which makes them harder to use for the operator than a double cut burr.

Double cut carbide burrs

The most used and easy to use geometry for ferrous metals for example carbon and alloy steels or soft stainless steels. The feature nearly everywhere handed cutting angles (cross cut style) and can produce a good surface finish in comparison with single cut burrs. A downside of the double cut burr is built up fringe 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, similar to a milling cutter, which prevents built-up edge and allows for large stock removal. The sharp cutting edges ensure a great surface finish.

Stainless Steel cut (Inox-Cut) carbide burrs

It features a high end grinding giving Thirty-five percent more stock removal when compared with conventional burr geometry and reduced heat develop at the technologically advanced for best tool life.

Steel cut carbide burrs

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

Single Cut vs Double Cut Carbide Rotary Burrs

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

The one cut, which can be suited to most ferrous metals, gives a faster cut with minimal clogging. The single cut comes with a single right hand spiral flute.

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