What exactly are solid carbide rotary burrs?

A rotary burr is really a solid carbide cutting tool employed 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 are often utilized in different metalworking applications for example deburring, stock removal, removal of sharp edges counter sinking, shaping, grinding and opening 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 manufactured from an assortment of Tungsten Carbide and Cobalt. Cobalt may be the binder holding the carbide grains together. Harder than virtually all metals, the power to be used at high speeds. It has a reduced chance of contamination and can be used on most materials.

What materials can solid carbide burrs be used on?

Carbide burrs can be used on all metals, including steel, stainless steel, Inconel, aluminium, iron, hardened steel and titanium. They may also be used on plastic, rubber, carbon fibre and fibre glass. With regards to the workpiece material, a particular cut type or coating are usually necessary for optimal performance, as an example alu-cut burrs feature wider chip pockets plus a single cut geometry to stop the aluminium from clogging up the burr, or perhaps a coated burr are usually necesary on heat resistant materials such as Inconel or metal.

How big a carbide burrs can be obtained?

Our selection of burrs starts from just 1mm diameter and go completely up to 25mm diameter.

What is the advantage of a coated carbide burr?

Coated carbide burrs offer longer tool life when compared with uncoated burrs, specifically in metals which can be hard, heat resistant or abrasive.

Carbide Burr Cut Types Explained

The most typical way of carbide burr cut type is often a double cut burr, also known as a cross cut or diamond cut burr which can be suited to most applications. However, there are several other geometry burrs to choose from which might aid performance in several applications:

Single cut carbide burrs:

These have a single right-hand spiral flute and they are most commonly applied to ferrous materials like certain or non ferrous materials for example copper, brass and aluminium. They feature faster cutting with minimal built up edge, though the disadvantage is that they pull up one way therefore which makes them harder to use for the operator than the usual double cut burr.

Double cut carbide burrs

The most used as well as 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 make a good surface finish when compared with single cut burrs. A disadvantage of the double cut burr is built up regarding 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, similar to a milling cutter, which prevents built-up edge and allows for large stock removal. The sharp cutting edges ensure an excellent surface finish.

Stainless Steel cut (Inox-Cut) carbide burrs

It provides a high performance grinding giving Thirty-five percent more stock removal in comparison to conventional burr geometry and reduced heat build-up in the leading edge for maximum tool life.

Steel cut carbide burrs

A unique 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 forms of Carbide rotary burr are single cut and double cut.

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

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