Fundamental Information Regarding Solid Carbide Rotary Burrs



What exactly are solid carbide rotary burrs?

A rotary burr is often a solid carbide cutting tool useful for removing material from your work piece by rotating at high speeds, usually inside a pneumatic air tool such as a pencil grinder or maybe a milling machine or machining centre. They can be used in different metalworking applications for example deburring, stock removal, removal of sharp edges counter sinking, shaping, grinding and opening an opening. Most burrs are produced 100% from solid carbide, although some people might larger diameter burrs feature a steel shank which has a brazed carbide head. ATA Garryson burrs are made from an assortment of Tungsten Carbide and Cobalt. Cobalt is the binder holding the carbide grains together. Harder than just about all metals, the nation's capacity to be used at high speeds. It has a reduced risk 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, stainless, Inconel, aluminium, surefire, hardened steel and titanium. They doubles on plastic, rubber, graphite and fibre glass. With respect to the workpiece material, a specific cut type or coating may be needed for optimal performance, for instance alu-cut burrs feature wider chip pockets as well as a single cut geometry to stop the aluminium from blocking up the burr, or perhaps a coated burr are usually necessary on heat resistant materials such as Inconel or stainless.

How big carbide burrs can be obtained?

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

What's the benefit from a coated carbide burr?

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

Carbide Burr Cut Types Explained

The commonest kind of carbide burr cut type is a double cut burr, also known as a cross cut or diamond cut burr that are ideal for the vast majority of applications. However, there are numerous other geometry burrs to pick from that might aid performance in numerous applications:

Single cut carbide burrs:

These come with a single right-hand spiral flute and they are normally utilized on ferrous materials including iron or non ferrous materials like copper, brass and aluminium. They feature faster cutting with minimal accumulated edge, though the disadvantage is because pull up one way therefore which makes them harder to use for the operator than the usual double cut burr.

Double cut carbide burrs

The most used as well as simple to use geometry for ferrous metals for example carbon and alloy steels or soft stainless steels. The feature right and left handed cutting angles (cross cut style) and can make a good surface finish when compared with single cut burrs. A problem with the double cut burr was made up regarding soft long chipping materials.

Aluminium cut (Alu-Cut) carbide burrs

Solid carbide burrs suitable 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 enables large stock removal. The sharp cutting edges ensure a fantastic surface finish.

Stainless-steel cut (Inox-Cut) carbide burrs

It possesses a high performance grinding giving 35 % more stock removal when compared with conventional burr geometry and reduced heat build-up at the cutting edge for best tool life.

Steel cut carbide burrs

A particular geometry double cut design especially 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 single cut, which is suitable for most ferrous metals, offers a faster cut with minimal clogging. The cut features 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.
