Precisely what are solid carbide rotary burrs?
A rotary burr can be a solid carbide cutting tool employed 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 maybe a milling machine or machining centre. They are often used in different metalworking applications such as deburring, stock removal, eliminating sharp edges counter sinking, shaping, grinding and opening an opening. Most burrs are manufactured 100% from solid carbide, but a majority of larger diameter burrs have a steel shank using 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, the power to be used at high speeds. It provides a reduced likelihood of contamination and is applied to most materials.
What materials can solid carbide burrs be used on?
Carbide burrs can be used on all metals, including steel, metal, Inconel, aluminium, certain, hardened steel and titanium. They could also be used on plastic, rubber, graphite and fibre glass. With regards to the workpiece material, a unique cut type or coating may be needed for optimal performance, as an example alu-cut burrs feature wider chip pockets and a single cut geometry to prevent the aluminium from taking up the burr, or a coated burr are usually necessary on heat resistant materials such as Inconel or stainless.
The size of carbide burrs can be purchased?
Our range of burrs starts from just 1mm diameter and go all the way up as much as 25mm diameter.
Exactly what is the benefit from a coated carbide burr?
Coated carbide burrs offer longer tool life when compared with uncoated burrs, especially in metals that are hard, heat resistant or abrasive.
Carbide Burr Cut Types Explained
The most common form of carbide burr cut type is a double cut burr, also known as a cross cut or diamond cut burr that are ideal for most applications. However, there are several other geometry burrs from which to choose which may aid performance in different applications:
Single cut carbide burrs:
These feature a single right-hand spiral flute and therefore are most often applied to ferrous materials like surefire or non ferrous materials like copper, brass and aluminium. They feature faster cutting with minimal piled up edge, nevertheless the disadvantage is they access in one direction therefore causing them to be harder for the operator when compared to a double cut burr.
Double cut carbide burrs
The most popular as well as simple to use geometry for ferrous metals for example carbon and alloy steels or soft stainless steels. The feature right and left handed cutting angles (cross cut style) and are able to produce a good surface finish in comparison with single cut burrs. A disadvantage of the double cut burr is built up fringe of soft long chipping materials.
Aluminium cut (Alu-Cut) carbide burrs
Solid carbide burrs created 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 great surface finish.
Metal cut (Inox-Cut) carbide burrs
It features a high end grinding giving 35 percent more stock removal compared to conventional burr geometry and reduced heat develop with the technologically advanced for optimum 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
The two most popular varieties of Carbide rotary burr are single cut and double cut.
The one cut, which can be ideal for most ferrous metals, gives a faster cut with minimal clogging. The cut incorporates a single right hand spiral flute.
The double cut, widely used on hard metals to deliver a finer, cleaner finish. The double cut has both right- and left-handed cutting angles.
