What exactly are solid carbide rotary burrs?

A rotary burr is really a solid carbide cutting tool used for removing material from your work piece by rotating at high speeds, usually inside a pneumatic air tool say for example a pencil grinder or maybe a milling machine or machining centre. They could be used in different metalworking applications like deburring, stock removal, removal of sharp edges counter sinking, shaping, grinding and opening an opening. Most burrs are manufactured 100% from solid carbide, although some people might larger diameter burrs have a steel shank which has a brazed carbide head. ATA Garryson burrs are manufactured from a mixture of Tungsten Carbide and Cobalt. Cobalt will be the binder holding the carbide grains together. Harder than almost all metals, her capacity to be applied out high speeds. It has a reduced probability of contamination and can be utilized on most materials.

What materials can solid carbide burrs provide on?

Carbide burrs can be used on all metals, including steel, stainless steel, Inconel, aluminium, 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 particular cut type or coating may be required for optimal performance, by way of 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 required on heat resistant materials such as Inconel or stainless steel.

What size carbide burrs are available?

Our variety of burrs starts from just 1mm diameter and go entirely around 25mm diameter.

Exactly what is the advantage of a coated carbide burr?

Coated carbide burrs offer longer tool life compared to uncoated burrs, especially in metals which are hard, heat resistant or abrasive.

Carbide Burr Cut Types Explained

The most frequent way of carbide burr cut type is often a double cut burr, also known as a cross cut or diamond cut burr which are suited to nearly all applications. However, there are lots of other geometry burrs to choose from which may aid performance in several applications:

Single cut carbide burrs:

These feature a single right-hand spiral flute and therefore are most commonly utilized on ferrous materials for example surefire or non ferrous materials like copper, brass and aluminium. They provide faster cutting with minimal built up edge, though the disadvantage is they pullup one way therefore making them harder to use for the operator than a double cut burr.

Double cut carbide burrs

The most popular and straightforward to utilize 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 create a good surface finish when compared with single cut burrs. A disadvantage of the double cut burr is built up side 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 permits large stock removal. The sharp cutting edges ensure a great surface finish.

Metal cut (Inox-Cut) carbide burrs

It comes with a high performance grinding giving 35 % more stock removal compared to conventional burr geometry and reduced heat build up at the leading edge for max tool life.

Steel cut carbide burrs

A special 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 single cut, that’s suitable for most ferrous metals, supplies a faster cut with minimal clogging. The one cut comes with a single right-hand spiral flute.

The double cut, widely used on hard metals to produce a finer, cleaner finish. The double cut has both right- and left-handed cutting angles.
