Precisely what are solid carbide rotary burrs?

A rotary burr can be a solid carbide cutting tool employed for removing material from your work piece by rotating at high speeds, usually in the pneumatic air tool say for example a pencil grinder or even a milling machine or machining centre. They can be employed in different metalworking applications for example deburring, stock removal, eliminating 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 feature a steel shank having a brazed carbide head. ATA Garryson burrs are made from a combination of Tungsten Carbide and Cobalt. Cobalt could be the binder holding the carbide grains together. Harder than almost all metals, her capacity to be used at high speeds. It possesses a reduced likelihood of contamination and could be suited for most materials.

What materials can solid carbide burrs be utilized on?

Carbide burrs can be used on all metals, including steel, stainless-steel, Inconel, aluminium, certain, hardened steel and titanium. They doubles on plastic, rubber, carbon fibre and fibre glass. With regards to the workpiece material, a certain cut type or coating are usually necessary for optimal performance, for instance alu-cut burrs feature wider chip pockets along with a single cut geometry to prevent the aluminium from clogging up the burr, or perhaps a coated burr are usually necessary on heat resistant materials like Inconel or stainless.

What size carbide burrs can be found?

Our selection of burrs starts from just 1mm diameter and go all the way approximately 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 can be hard, heat resistant or abrasive.

Carbide Burr Cut Types Explained

The most typical form of carbide burr cut type is a double cut burr, often known as a cross cut or diamond cut burr that are suitable for the vast majority of applications. However, there are many other geometry burrs to choose from which can aid performance in different applications:

Single cut carbide burrs:

These come with a single right hand spiral flute and they are mostly utilized on ferrous materials like iron or non ferrous materials like copper, brass and aluminium. They feature faster cutting with minimal built up edge, nevertheless the disadvantage is that they access in one direction therefore which makes them harder for the operator than a double cut burr.

Double cut carbide burrs

The most famous and simple to work with geometry for ferrous metals such as carbon and alloy steels or soft stainless steels. The feature left and right handed cutting angles (cross cut style) and can make a good surface finish in comparison with single cut burrs. A drawback to the double cut burr is made up side 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, much like 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 provides a top rated grinding giving 35 % more stock removal compared to conventional burr geometry and reduced heat build up with the technologically advanced for best tool life.

Steel cut carbide burrs

A unique geometry double cut design specifically 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, that’s suited to most ferrous metals, gives 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 provide a finer, cleaner finish. The double cut has both right- and left-handed cutting angles.
