Significant Understanding Of Solid Carbide Rotary Burrs

What are solid carbide rotary burrs?

A rotary burr is really a solid carbide cutting tool used for removing material from your work piece by rotating at high speeds, usually inside a pneumatic air tool like a pencil grinder or even a milling machine or machining centre. They are often found in different metalworking applications for example deburring, stock removal, removal of sharp edges counter sinking, shaping, grinding and examining a hole. Most burrs are created 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 a combination of Tungsten Carbide and Cobalt. Cobalt could be the binder holding the carbide grains together. Harder than virtually all metals, her capability to be used at high speeds. It provides a reduced likelihood of contamination and could be utilized on most materials.

What materials can solid carbide burrs provide on?

Carbide burrs may be used on all metals, including steel, stainless, Inconel, aluminium, surefire, hardened steel and titanium. They can also be used on plastic, rubber, carbon fibre and fibre glass. Based on the workpiece material, a certain cut type or coating may be required for optimal performance, for instance alu-cut burrs feature wider chip pockets and a single cut geometry to stop the aluminium from clogging up the burr, or even a coated burr may be needed on heat resistant materials for example Inconel or stainless.

The size of carbide burrs can be purchased?

Our range of burrs starts from just 1mm diameter and go entirely as much as 25mm diameter.

What’s the good thing about a coated carbide burr?

Coated carbide burrs offer longer tool life in comparison with uncoated burrs, especially in metals that are hard, heat resistant or abrasive.

Carbide Burr Cut Types Explained

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

Single cut carbide burrs:

These come with a single right hand spiral flute and are most often suited for ferrous materials such as iron or non ferrous materials including copper, brass and aluminium. They provide faster cutting with minimal built up edge, even so the disadvantage is because pullup one way therefore causing them to be harder to use for the operator compared to a double cut burr.

Double cut carbide burrs

The most used and straightforward to make use of 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 are able to make a good surface finish compared to single cut burrs. A disadvantage of the double cut burr is created 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, similar to 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 provides a top rated grinding giving 35 % more stock removal in comparison to conventional burr geometry and reduced heat build up on the leading 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 kinds of Carbide rotary burr are single cut and double cut.

The only cut, that’s well suited for most ferrous metals, supplies a faster cut with minimal clogging. The one cut incorporates a single right-hand spiral flute.

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