What are solid carbide rotary burrs?
A rotary burr is often a solid carbide cutting tool utilized for removing material from your work piece by rotating at high speeds, usually within a pneumatic air tool for instance a pencil grinder or possibly a milling machine or machining centre. They may be employed in different metalworking applications like deburring, stock removal, eliminating sharp edges counter sinking, shaping, grinding and opening a hole. Most burrs are created 100% from solid carbide, however, some larger diameter burrs have a steel shank having a brazed carbide head. ATA Garryson burrs are produced from an assortment of Tungsten Carbide and Cobalt. Cobalt could be the binder holding the carbide grains together. Harder than almost all metals, the ability to be applied out high speeds. It features a reduced likelihood of contamination and could be suited for most materials.
What materials can solid carbide burrs supply on?
Carbide burrs can be utilized on all metals, including steel, stainless, Inconel, aluminium, iron, hardened steel and titanium. They can 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 needed for optimal performance, for instance alu-cut burrs feature wider chip pockets along with a single cut geometry to stop the aluminium from taking up the burr, or a coated burr may be needed on heat resistant materials such as Inconel or stainless-steel.
The size of carbide burrs are available?
Our range of burrs starts from just 1mm diameter and go all the way 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, particularly in metals which can be hard, heat resistant or abrasive.
Carbide Burr Cut Types Explained
The most frequent form of carbide burr cut type is often a double cut burr, also referred to as a cross cut or diamond cut burr which can be suited to most applications. However, there are lots of other geometry burrs to pick from which can aid performance in different applications:
Single cut carbide burrs:
These come with a single right hand spiral flute and therefore are mostly used on ferrous materials like cast iron or non ferrous materials including copper, brass and aluminium. They offer faster cutting with minimal developed edge, nevertheless the disadvantage is because access one way therefore making them harder for the operator than a double cut burr.
Double cut carbide burrs
Typically the most popular and easy to utilize 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 create a good surface finish in comparison with single cut burrs. A disadvantage of the double cut burr was made up edge of soft long chipping materials.
Aluminium cut (Alu-Cut) carbide burrs
Solid carbide burrs made 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 great surface finish.
Metal cut (Inox-Cut) carbide burrs
It provides a powerful grinding giving 35 percent more stock removal in comparison to conventional burr geometry and reduced heat build-up on the leading edge for best tool life.
Steel cut carbide burrs
A special geometry double cut design specifically for high stock removal applications on carbon and alloy steels.
Single Cut vs Double Cut Carbide Rotary Burrs
Two of the most popular forms of Carbide rotary burr are single cut and double cut.
The one cut, that’s well suited for most ferrous metals, supplies a faster cut with minimal clogging. The cut comes with a single right-hand spiral flute.
The double cut, commonly used on hard metals to produce a finer, cleaner finish. The double cut has both right- and left-handed cutting angles.
