Fundamental Info On Solid Carbide Rotary Burrs

Exactly what are solid carbide rotary burrs?

A rotary burr is really a solid carbide cutting tool employed for removing material coming from a work piece by rotating at high speeds, usually inside a pneumatic air tool such as a pencil grinder or maybe a milling machine or machining centre. They may be employed in different metalworking applications like deburring, stock removal, elimination of sharp edges counter sinking, shaping, grinding and checking a dent. Most burrs are created 100% from solid carbide, however some larger diameter burrs come with a steel shank using a brazed carbide head. ATA Garryson burrs are manufactured from a combination of Tungsten Carbide and Cobalt. Cobalt could be the binder holding the carbide grains together. Harder than just about all metals, the nation’s power to be used at high speeds. It has a reduced probability of contamination and can be suited for most materials.

What materials can solid carbide burrs supply on?

Carbide burrs can be used on all metals, including steel, stainless steel, Inconel, aluminium, cast iron, hardened steel and titanium. They may also be used on plastic, rubber, carbon fibre and fibre glass. With regards to the workpiece material, a certain cut type or coating are usually necesary for optimal performance, as an example alu-cut burrs feature wider chip pockets plus a single cut geometry to prevent the aluminium from blocking up the burr, or even a coated burr are usually necessary on heat resistant materials like Inconel or stainless.

What size carbide burrs can be purchased?

Our variety of burrs starts from just 1mm diameter and go completely up to 25mm diameter.

Is there a advantage of a coated carbide burr?

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

Carbide Burr Cut Types Explained

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

Single cut carbide burrs:

These feature a single right-hand spiral flute and are mostly used on ferrous materials including surefire or non ferrous materials such as copper, brass and aluminium. They offer faster cutting with minimal accumulated edge, however the disadvantage is they pullup one way therefore making them harder to use for the operator compared to a double cut burr.

Double cut carbide burrs

The most used as well as simple to make use of geometry for ferrous metals including carbon and alloy steels or soft stainless steels. The feature all over the place handed cutting angles (cross cut style) and can produce a good surface finish compared to single cut burrs. A drawback to the double cut burr is built up regarding soft long chipping materials.

Aluminium cut (Alu-Cut) carbide burrs

Solid carbide burrs created 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 enables large stock removal. The sharp cutting edges ensure a good surface finish.

Stainless Steel cut (Inox-Cut) carbide burrs

It provides a high end grinding giving 35 percent more stock removal in comparison with conventional burr geometry and reduced heat build up with the innovative for best tool life.

Steel cut carbide burrs

An exclusive 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 can be well suited for most ferrous metals, supplies a faster cut with minimal clogging. The only cut features a single right hand spiral flute.

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