What are solid carbide rotary burrs?
A rotary burr is often a solid carbide cutting tool useful for removing material from the work piece by rotating at high speeds, usually in a pneumatic air tool for instance a pencil grinder or possibly a milling machine or machining centre. They can be utilized in different metalworking applications for example deburring, stock removal, removal of sharp edges counter sinking, shaping, grinding and opening a dent. Most burrs are made 100% from solid carbide, however some larger diameter burrs feature a steel shank using a brazed carbide head. ATA Garryson burrs are manufactured from an assortment of Tungsten Carbide and Cobalt. Cobalt is the binder holding the carbide grains together. Harder than almost all metals, her capability to be applied out high speeds. It features a reduced risk of contamination and is applied to most materials.
What materials can solid carbide burrs be used on?
Carbide burrs can be utilized on all metals, including steel, metal, Inconel, aluminium, surefire, hardened steel and titanium. They may also be used on plastic, rubber, graphite and fibre glass. With respect to the workpiece material, a specific cut type or coating may be needed for optimal performance, for instance alu-cut burrs feature wider chip pockets as well as a single cut geometry to prevent the aluminium from blocking up the burr, or a coated burr are usually necessary on heat resistant materials including Inconel or stainless steel.
How big a carbide burrs can be obtained?
Our array of burrs starts from just 1mm diameter and go all the way approximately 25mm diameter.
Is there a advantage of 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 really a double cut burr, often known as a cross cut or diamond cut burr that happen to be well suited for most applications. However, there are several other geometry burrs to select from which can aid performance in different applications:
Single cut carbide burrs:
These come with a single right-hand spiral flute and are most commonly suited for ferrous materials like iron or non ferrous materials including copper, brass and aluminium. They feature faster cutting with minimal piled up edge, even so the disadvantage is because pull up in one direction therefore causing them to be harder to use for the operator than a double cut burr.
Double cut carbide burrs
Typically the most popular and straightforward to make use of 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 can develop a good surface finish when compared with single cut burrs. A downside of the double cut burr was made up regarding 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, such as a milling cutter, which prevents built-up edge and allows for large stock removal. The sharp cutting edges ensure a good surface finish.
Stainless Steel cut (Inox-Cut) carbide burrs
It comes with a high end grinding giving 35 % more stock removal in comparison with conventional burr geometry and reduced heat build-up at the leading edge for maximum tool life.
Steel cut carbide burrs
A special geometry double cut design particularly 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 suitable for most ferrous metals, provides 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 produce a finer, cleaner finish. The double cut has both right- and left-handed cutting angles.
