Precisely what are solid carbide rotary burrs?
A rotary burr is a solid carbide cutting tool useful for removing material coming from a work piece by rotating at high speeds, usually inside a pneumatic air tool like a pencil grinder or possibly a milling machine or machining centre. They could be used in different metalworking applications for example deburring, stock removal, eliminating sharp edges counter sinking, shaping, grinding and opening an opening. 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 variety of Tungsten Carbide and Cobalt. Cobalt is the binder holding the carbide grains together. Harder than almost all metals, the ability to be used at high speeds. It provides a reduced probability of contamination and can be utilized on most materials.
What materials can solid carbide burrs be utilized on?
Carbide burrs can be used on all metals, including steel, metal, Inconel, aluminium, cast iron, hardened steel and titanium. They could also be used on plastic, rubber, carbon fibre and fibre glass. With regards to the workpiece material, a unique cut type or coating may be required for optimal performance, as an example alu-cut burrs feature wider chip pockets as well as a single cut geometry to prevent the aluminium from obstructing the burr, or perhaps a coated burr may be needed on heat resistant materials including Inconel or stainless-steel.
How big a carbide burrs are available?
Our array of burrs starts from just 1mm diameter and go all the way up as much as 25mm diameter.
Exactly what is the benefit from a coated carbide burr?
Coated carbide burrs offer longer tool life in comparison with uncoated burrs, specifically in metals which can be hard, heat resistant or abrasive.
Carbide Burr Cut Types Explained
The most common form of carbide burr cut type is often a double cut burr, also known as a cross cut or diamond cut burr which can be ideal for most applications. However, there are numerous other geometry burrs to select from which can aid performance in various applications:
Single cut carbide burrs:
These have a single right-hand spiral flute and therefore are most commonly utilized on ferrous materials including surefire or non ferrous materials such as copper, brass and aluminium. They provide faster cutting with minimal developed edge, even so the disadvantage is that they pull-up in one direction therefore making them harder for the operator than a double cut burr.
Double cut carbide burrs
The most used and simple to work with geometry for ferrous metals including carbon and alloy steels or soft stainless steels. The feature left and right handed cutting angles (cross cut style) and can produce a good surface finish in comparison to single cut burrs. A problem with the double cut burr is created up side of soft long chipping materials.
Aluminium cut (Alu-Cut) carbide burrs
Solid carbide burrs suitable 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 enables large stock removal. The sharp cutting edges ensure a good surface finish.
Stainless-steel cut (Inox-Cut) carbide burrs
It features a high end grinding giving 35 percent more stock removal in comparison to conventional burr geometry and reduced heat build up at the technologically advanced for maximum 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
Two of the most popular varieties of Carbide rotary burr are single cut and double cut.
The cut, which is well suited for most ferrous metals, offers a faster cut with minimal clogging. The single cut incorporates a single right-hand spiral flute.
The double cut, popular on hard metals to deliver a finer, cleaner finish. The double cut has both right- and left-handed cutting angles.
