Important Knowledge About Solid Carbide Rotary Burrs

What are solid carbide rotary burrs?

A rotary burr is a solid carbide cutting tool useful for removing material from the work piece by rotating at high speeds, usually within a pneumatic air tool such as a pencil grinder or even a milling machine or machining centre. They can be utilized in different metalworking applications like deburring, stock removal, removing sharp edges counter sinking, shaping, grinding and examining a hole. Most burrs are manufactured 100% from solid carbide, although some people might larger diameter burrs come with a steel shank using a brazed carbide head. ATA Garryson burrs are made from a mixture of Tungsten Carbide and Cobalt. Cobalt will be the binder holding the carbide grains together. Harder than nearly all metals, the nation’s capacity to be utilized at high speeds. It features a reduced probability of contamination and could be utilized on most materials.

What materials can solid carbide burrs supply on?

Carbide burrs works extremely well on all metals, including steel, stainless-steel, Inconel, aluminium, iron, hardened steel and titanium. They doubles on plastic, rubber, carbon fibre and fibre glass. With respect to the workpiece material, a certain cut type or coating are usually necesary for optimal performance, as an example alu-cut burrs feature wider chip pockets as well as a single cut geometry to stop the aluminium from clogging up the burr, or a coated burr are usually necesary on heat resistant materials for example Inconel or metal.

What size carbide burrs can be obtained?

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

What is the advantage of a coated carbide burr?

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

Carbide Burr Cut Types Explained

The most frequent kind of carbide burr cut type is really a double cut burr, often known as a cross cut or diamond cut burr that happen to be suited to almost all applications. However, there are lots of other geometry burrs from which to choose which may aid performance in several applications:

Single cut carbide burrs:

These have a single right-hand spiral flute and so are most often used on ferrous materials like surefire or non ferrous materials for example copper, brass and aluminium. They offer faster cutting with minimal built up edge, however the disadvantage is they pullup in one direction therefore making them harder to use for the operator compared to a double cut burr.

Double cut carbide burrs

The most popular and easy to use geometry for ferrous metals for example carbon and alloy steels or soft stainless steels. The feature all over the place handed cutting angles (cross cut style) and are able to make a good surface finish in comparison with single cut burrs. A problem with the double cut burr is created up edge of soft long chipping materials.

Aluminium cut (Alu-Cut) carbide burrs

Solid carbide burrs designed for experience soft long chipping materials including aluminium, copper, brass and plastic. They feature sharp cutting edges and deep flute pockets, much like a milling cutter, which prevents built-up edge and provides for large stock removal. The sharp cutting edges ensure a good surface finish.

Stainless cut (Inox-Cut) carbide burrs

It features a top rated grinding giving 35 percent more stock removal in comparison to conventional burr geometry and reduced heat increase with the innovative for max tool life.

Steel cut carbide burrs

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

Single Cut vs Double Cut Carbide Rotary Burrs

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

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

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