Key Specifics About Solid Carbide Rotary Burrs

Precisely what are solid carbide rotary burrs?

A rotary burr is a solid carbide cutting tool useful for removing material coming from a work piece by rotating at high speeds, usually in the pneumatic air tool like a pencil grinder or even a milling machine or machining centre. They may be utilized in different metalworking applications including deburring, stock removal, removal of sharp edges counter sinking, shaping, grinding and examining a dent. Most burrs are manufactured 100% from solid carbide, however, some larger diameter burrs include a steel shank having a brazed carbide head. ATA Garryson burrs are manufactured from a combination of Tungsten Carbide and Cobalt. Cobalt is the binder holding the carbide grains together. Harder than almost all metals, it has the capacity to be used at high speeds. It has a reduced risk of contamination and could be applied to most materials.

What materials can solid carbide burrs supply on?

Carbide burrs may be used on all metals, including steel, stainless steel, Inconel, aluminium, iron, hardened steel and titanium. They could also be used on plastic, rubber, carbon fibre and fibre glass. Depending on the workpiece material, a unique cut type or coating may be required for optimal performance, as an example alu-cut burrs feature wider chip pockets plus a single cut geometry to stop the aluminium from blocking up the burr, or possibly a coated burr are usually necessary on heat resistant materials like Inconel or stainless.

How big carbide burrs can be found?

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

Exactly what is the good thing about 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 commonest form of carbide burr cut type is really a double cut burr, also known as a cross cut or diamond cut burr which are suitable for nearly all applications. However, there are several other geometry burrs to select from which may aid performance in numerous applications:

Single cut carbide burrs:

These have a single right hand spiral flute and so are most commonly applied to ferrous materials like cast iron or non ferrous materials including copper, brass and aluminium. They supply faster cutting with minimal built up edge, nevertheless the disadvantage is that they pull up one way therefore making them harder to use for the operator than a double cut burr.

Double cut carbide burrs

The most used and simple to utilize geometry for ferrous metals including carbon and alloy steels or soft stainless steels. The feature all over the place handed cutting angles (cross cut style) and are able to develop a good surface finish when compared with single cut burrs. A downside of the double cut burr was made up fringe of soft long chipping materials.

Aluminium cut (Alu-Cut) carbide burrs

Solid carbide burrs suitable for experience 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 provides for large stock removal. The sharp cutting edges ensure an excellent surface finish.

Stainless cut (Inox-Cut) carbide burrs

It features a powerful grinding giving 35 percent more stock removal when compared with conventional burr geometry and reduced heat develop with the innovative for maximum 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

Two of the most popular types of Carbide rotary burr are single cut and double cut.

The cut, which can be suitable for most ferrous metals, supplies a faster cut with minimal clogging. The one cut features a single right-hand spiral flute.

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