What exactly are solid carbide rotary burrs?
A rotary burr can be 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 such as a pencil grinder or possibly a milling machine or machining centre. They may be employed in different metalworking applications such as deburring, stock removal, eliminating sharp edges counter sinking, shaping, grinding and examining a hole. Most burrs are made 100% from solid carbide, but a majority of larger diameter burrs include a steel shank which has a brazed carbide head. ATA Garryson burrs are manufactured from a mixture of Tungsten Carbide and Cobalt. Cobalt could be the binder holding the carbide grains together. Harder than virtually all metals, the ability to be utilized at high speeds. It possesses a reduced chance of contamination and is suited for most materials.
What materials can solid carbide burrs be used on?
Carbide burrs can be used on all metals, including steel, metal, Inconel, aluminium, iron, hardened steel and titanium. They doubles on plastic, rubber, carbon fibre and fibre glass. Based on the workpiece material, a unique cut type or coating are usually necesary for optimal performance, as an example alu-cut burrs feature wider chip pockets and a single cut geometry to avoid the aluminium from obstructing the burr, or a coated burr may be required on heat resistant materials such as Inconel or stainless.
How big a carbide burrs can be purchased?
Our selection of burrs starts from just 1mm diameter and go entirely approximately 25mm diameter.
What is the benefit of a coated carbide burr?
Coated carbide burrs offer longer tool life in comparison to uncoated burrs, specially in metals that are hard, heat resistant or abrasive.
Carbide Burr Cut Types Explained
The most typical 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 the vast majority of applications. However, there are numerous other geometry burrs to pick from which might aid performance in numerous applications:
Single cut carbide burrs:
These include a single right hand spiral flute and are normally applied to ferrous materials like cast iron or non ferrous materials for example copper, brass and aluminium. They offer faster cutting with minimal piled up edge, even so the disadvantage is 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 famous and easy to use geometry for ferrous metals like carbon and alloy steels or soft stainless steels. The feature left and right handed cutting angles (cross cut style) and can make a good surface finish in comparison with single cut burrs. A disadvantage of the double cut burr is made up regarding soft long chipping materials.
Aluminium cut (Alu-Cut) carbide burrs
Solid carbide burrs created 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 permits large stock removal. The sharp cutting edges ensure an excellent surface finish.
Stainless cut (Inox-Cut) carbide burrs
It comes with a high performance grinding giving 35 % more stock removal in comparison with conventional burr geometry and reduced heat build up on the leading edge for optimum tool life.
Steel cut carbide burrs
An exclusive 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 only cut, that’s suited to most ferrous metals, offers a faster cut with minimal clogging. The single cut features a single right hand spiral flute.
The double cut, widely used on hard metals to produce a finer, cleaner finish. The double cut has both right- and left-handed cutting angles.
