What exactly are solid carbide rotary burrs?
A rotary burr is often a solid carbide cutting tool used for removing material from a work piece by rotating at high speeds, usually in a pneumatic air tool say for example a pencil grinder or possibly a milling machine or machining centre. They may be utilized in different metalworking applications for example deburring, stock removal, eliminating sharp edges counter sinking, shaping, grinding and checking a dent. Most burrs are manufactured 100% from solid carbide, however, some larger diameter burrs include a steel shank with a brazed carbide head. ATA Garryson burrs are produced from a mixture of Tungsten Carbide and Cobalt. Cobalt will be the binder holding the carbide grains together. Harder than almost all metals, her power to be used at high speeds. It has a reduced risk of contamination and can be suited for most materials.
What materials can solid carbide burrs supply on?
Carbide burrs can be utilized on all metals, including steel, stainless steel, Inconel, aluminium, cast iron, hardened steel and titanium. They could also be used on plastic, rubber, graphite and fibre glass. Based on the workpiece material, a specific cut type or coating are usually necessary for optimal performance, by way of example alu-cut burrs feature wider chip pockets along with a single cut geometry to avoid the aluminium from clogging up the burr, or possibly a coated burr are usually necesary on heat resistant materials including Inconel or stainless steel.
How big a carbide burrs can be found?
Our range of burrs starts from just 1mm diameter and go all the way up to 25mm diameter.
Is there a benefit of a coated carbide burr?
Coated carbide burrs offer longer tool life compared to uncoated burrs, particularly in metals which can be hard, heat resistant or abrasive.
Carbide Burr Cut Types Explained
The most common form 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 the vast majority of applications. However, there are numerous other geometry burrs from which to choose which may aid performance in various applications:
Single cut carbide burrs:
These come with a single right-hand spiral flute and therefore are normally utilized on ferrous materials such as certain or non ferrous materials such as copper, brass and aluminium. They provide faster cutting with minimal built up edge, though the disadvantage is because they pull up one way therefore driving them to harder for the operator than a double cut burr.
Double cut carbide burrs
Typically the most popular as well as simple to use geometry for ferrous metals including carbon and alloy steels or soft stainless steels. The feature nearly everywhere handed cutting angles (cross cut style) and are able to create a good surface finish in comparison with single cut burrs. A disadvantage of the double cut burr is built 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, such as a milling cutter, which prevents built-up edge and permits large stock removal. The sharp cutting edges ensure an excellent surface finish.
Metal cut (Inox-Cut) carbide burrs
It features a high end grinding giving 35 % more stock removal when compared with conventional burr geometry and reduced heat build-up at the innovative for maximum tool life.
Steel cut carbide burrs
A unique 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 types of Carbide rotary burr are single cut and double cut.
The single cut, which can be well suited for most ferrous metals, gives a faster cut with minimal clogging. The single cut comes with a single right-hand spiral flute.
The double cut, popular on hard metals to provide a finer, cleaner finish. The double cut has both right- and left-handed cutting angles.
