What exactly are solid carbide rotary burrs?

A rotary burr is a solid carbide cutting tool employed for removing material from the work piece by rotating at high speeds, usually within 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 for example deburring, stock removal, eliminating sharp edges counter sinking, shaping, grinding and checking a dent. Most burrs are made 100% from solid carbide, however, some larger diameter burrs have a steel shank which has a brazed carbide head. ATA Garryson burrs are made of an assortment of Tungsten Carbide and Cobalt. Cobalt could be the binder holding the carbide grains together. Harder than nearly all metals, the capability to be utilized at high speeds. It has a reduced chance of contamination and could be used on most materials.

What materials can solid carbide burrs supply on?

Carbide burrs can be used on all metals, including steel, stainless-steel, Inconel, aluminium, cast iron, hardened steel and titanium. They can also be used on plastic, rubber, carbon fibre and fibre glass. With respect to the workpiece material, a certain cut type or coating may be needed for optimal performance, by way of example alu-cut burrs feature wider chip pockets plus a single cut geometry to stop the aluminium from taking up the burr, or possibly a coated burr may be required on heat resistant materials such as Inconel or stainless.

What size carbide burrs can be purchased?

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

Is there a good thing about a coated carbide burr?

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

Carbide Burr Cut Types Explained

The most common kind of carbide burr cut type is often a double cut burr, also called a cross cut or diamond cut burr which are ideal for almost all applications. However, there are numerous other geometry burrs from which to choose which can aid performance in numerous applications:

Single cut carbide burrs:

These come with a single right hand spiral flute and they are most often applied to ferrous materials such as certain or non ferrous materials including copper, brass and aluminium. They offer faster cutting with minimal piled up edge, though the disadvantage is because they pull-up in one direction 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 for example carbon and alloy steels or soft stainless steels. The feature nearly everywhere handed cutting angles (cross cut style) and are able to create a good surface finish when compared with single cut burrs. A disadvantage of the double cut burr is built up fringe of 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, such as a milling cutter, which prevents built-up edge and allows for large stock removal. The sharp cutting edges ensure a fantastic surface finish.

Stainless-steel cut (Inox-Cut) carbide burrs

It comes with a high end grinding giving 35 percent more stock removal when compared with conventional burr geometry and reduced heat develop on the cutting edge for max tool life.

Steel cut carbide burrs

A special geometry double cut design specifically 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 cut, which is ideal for most ferrous metals, gives a faster cut with minimal clogging. The one cut incorporates 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.
