What exactly are solid carbide rotary burrs?
A rotary burr is often 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 for instance a pencil grinder or possibly a milling machine or machining centre. They can be found in different metalworking applications like deburring, stock removal, removing sharp edges counter sinking, shaping, grinding and examining a dent. Most burrs are created 100% from solid carbide, however some 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, her ability to be applied out high speeds. It features a reduced likelihood of contamination and can be used on most materials.
What materials can solid carbide burrs provide on?
Carbide burrs may be used on all metals, including steel, stainless-steel, Inconel, aluminium, certain, hardened steel and titanium. They may also be used on plastic, rubber, carbon fibre and fibre glass. With respect to the workpiece material, a particular cut type or coating may be required for optimal performance, as an example alu-cut burrs feature wider chip pockets and a single cut geometry to prevent the aluminium from blocking up the burr, or possibly a coated burr are usually necesary on heat resistant materials like Inconel or stainless.
What size carbide burrs can be purchased?
Our array of burrs starts from just 1mm diameter and go all the way up as much as 25mm diameter.
Is there a benefit from a coated carbide burr?
Coated carbide burrs offer longer tool life compared to uncoated burrs, specially in metals which might be hard, heat resistant or abrasive.
Carbide Burr Cut Types Explained
The commonest type 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 to select from which can aid performance in various applications:
Single cut carbide burrs:
These feature a single right-hand spiral flute and so are normally used on ferrous materials such as iron or non ferrous materials like copper, brass and aluminium. They provide faster cutting with minimal accumulated edge, even so the disadvantage is they pullup one way therefore making them harder to use for the operator when compared to a double cut burr.
Double cut carbide burrs
Typically the most popular as well as simple to use geometry for ferrous metals like 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 problem with the double cut burr is built up regarding soft long chipping materials.
Aluminium cut (Alu-Cut) carbide burrs
Solid carbide burrs made 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 enables large stock removal. The sharp cutting edges ensure a good surface finish.
Metal cut (Inox-Cut) carbide burrs
It possesses a high end grinding giving Thirty-five percent more stock removal in comparison to conventional burr geometry and reduced heat increase at the innovative for max 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 varieties of Carbide rotary burr are single cut and double cut.
The one cut, that’s well suited for most ferrous metals, gives a faster cut with minimal clogging. The 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.
