Precisely what are solid carbide rotary burrs?
A rotary burr is often a solid carbide cutting tool employed for removing material from your work piece by rotating at high speeds, usually within a pneumatic air tool such as a pencil grinder or possibly a milling machine or machining centre. They could be used in different metalworking applications including deburring, stock removal, eliminating sharp edges counter sinking, shaping, grinding and opening up a dent. Most burrs are created 100% from solid carbide, however some larger diameter burrs come with a steel shank having a brazed carbide head. ATA Garryson burrs are made from a mixture of Tungsten Carbide and Cobalt. Cobalt may be the binder holding the carbide grains together. Harder than just about all metals, it has the capability to be applied out high speeds. It provides a reduced likelihood of contamination and is suited for most materials.
What materials can solid carbide burrs supply on?
Carbide burrs may be used on all metals, including steel, metal, Inconel, aluminium, certain, hardened steel and titanium. They can also be used on plastic, rubber, carbon fibre and fibre glass. Depending on the workpiece material, a specific cut type or coating are usually necessary for optimal performance, for example alu-cut burrs feature wider chip pockets along with a single cut geometry to stop the aluminium from blocking up the burr, or a coated burr are usually necesary on heat resistant materials including Inconel or stainless-steel.
What size carbide burrs are available?
Our variety of burrs starts from just 1mm diameter and go all the way up as much as 25mm diameter.
What’s the good thing about a coated carbide burr?
Coated carbide burrs offer longer tool life in comparison with uncoated burrs, particularly in metals which might be hard, heat resistant or abrasive.
Carbide Burr Cut Types Explained
The commonest form of carbide burr cut type is a double cut burr, also referred to as a cross cut or diamond cut burr which can be suited to almost all applications. However, there are many other geometry burrs to select from that might aid performance in different applications:
Single cut carbide burrs:
These feature a single right hand spiral flute and are normally used on ferrous materials for example cast iron or non ferrous materials such as copper, brass and aluminium. They provide faster cutting with minimal developed edge, though the disadvantage is they pullup in one direction therefore causing them to be harder to use for the operator than a double cut burr.
Double cut carbide burrs
The most popular and simple to work with geometry for ferrous metals for example carbon and alloy steels or soft stainless steels. The feature left and right handed cutting angles (cross cut style) and are able to create a good surface finish in comparison with single cut burrs. A drawback to the double cut burr is made up regarding soft long chipping materials.
Aluminium cut (Alu-Cut) carbide burrs
Solid carbide burrs made for experience soft long chipping materials including aluminium, copper, brass and plastic. They feature sharp cutting edges and deep flute pockets, much like a milling cutter, which prevents built-up edge and provides for large stock removal. The sharp cutting edges ensure a great surface finish.
Stainless cut (Inox-Cut) carbide burrs
It features a powerful grinding giving 35 percent more stock removal in comparison with conventional burr geometry and reduced heat develop at 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 only cut, that’s well suited for 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 provide a finer, cleaner finish. The double cut has both right- and left-handed cutting angles.
