What exactly are solid carbide rotary burrs?
A rotary burr can be a solid carbide cutting tool useful for removing material from a work piece by rotating at high speeds, usually within a pneumatic air tool like a pencil grinder or maybe a milling machine or machining centre. They could be found in different metalworking applications like deburring, stock removal, eliminating sharp edges counter sinking, shaping, grinding and examining a hole. Most burrs are created 100% from solid carbide, however, some larger diameter burrs feature a steel shank which has a brazed carbide head. ATA Garryson burrs are produced from a variety of Tungsten Carbide and Cobalt. Cobalt is the binder holding the carbide grains together. Harder than just about all metals, her ability to be used at high speeds. It has a reduced likelihood of contamination and can be utilized on most materials.
What materials can solid carbide burrs be utilized on?
Carbide burrs works extremely well on all metals, including steel, metal, Inconel, aluminium, surefire, hardened steel and titanium. They may also be used on plastic, rubber, carbon fibre and fibre glass. With regards to the workpiece material, a specific cut type or coating may be required for optimal performance, for example alu-cut burrs feature wider chip pockets and a single cut geometry to stop the aluminium from clogging up the burr, or even a coated burr may be required on heat resistant materials like Inconel or metal.
What size carbide burrs can be found?
Our variety of burrs starts from just 1mm diameter and go entirely up to 25mm diameter.
Is there a good thing about a coated carbide burr?
Coated carbide burrs offer longer tool life in comparison with uncoated burrs, specially in metals which are hard, heat resistant or abrasive.
Carbide Burr Cut Types Explained
The commonest form of carbide burr cut type can be a double cut burr, often known as a cross cut or diamond cut burr which are ideal for most applications. However, there are numerous other geometry burrs to pick from which can aid performance in various applications:
Single cut carbide burrs:
These come with a single right-hand spiral flute and they are most often used on ferrous materials like iron or non ferrous materials such as copper, brass and aluminium. They supply faster cutting with minimal built up edge, nevertheless the disadvantage is they pull up in one direction therefore making them harder for the operator than a double cut burr.
Double cut carbide burrs
Typically the most popular and straightforward to use geometry for ferrous metals such as carbon and alloy steels or soft stainless steels. The feature right and left handed cutting angles (cross cut style) and are able to develop a good surface finish compared to single cut burrs. A downside of the double cut burr is made up fringe of 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 enables large stock removal. The sharp cutting edges ensure a fantastic surface finish.
Stainless Steel cut (Inox-Cut) carbide burrs
It features a powerful grinding giving 35 % more stock removal in comparison with conventional burr geometry and reduced heat build-up on the cutting edge for best 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 forms of Carbide rotary burr are single cut and double cut.
The one cut, that is ideal for most ferrous metals, gives a faster cut with minimal clogging. The only cut includes a single right hand spiral flute.
The double cut, commonly used on hard metals to deliver a finer, cleaner finish. The double cut has both right- and left-handed cutting angles.
