Key Details About Solid Carbide Rotary Burrs

Precisely what are solid carbide rotary burrs?

A rotary burr is a solid carbide cutting tool utilized for removing material coming from a work piece by rotating at high speeds, usually in a pneumatic air tool like a pencil grinder or even a milling machine or machining centre. They are often utilized in different metalworking applications including deburring, stock removal, removal of sharp edges counter sinking, shaping, grinding and checking a hole. Most burrs are produced 100% from solid carbide, however some larger diameter burrs feature a steel shank which has a brazed carbide head. ATA Garryson burrs are produced from a combination of Tungsten Carbide and Cobalt. Cobalt may be the binder holding the carbide grains together. Harder than just about all metals, the power to be utilized at high speeds. It has a reduced probability of contamination and could be used on most materials.

What materials can solid carbide burrs supply on?

Carbide burrs may be used on all metals, including steel, stainless steel, Inconel, aluminium, cast iron, hardened steel and titanium. They doubles 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 stop the aluminium from obstructing the burr, or possibly a coated burr are usually necesary on heat resistant materials like Inconel or stainless.

The size of carbide burrs are available?

Our array of burrs starts from just 1mm diameter and go entirely approximately 25mm diameter.

Is there a 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 typical form of carbide burr cut type is often a double cut burr, often known as a cross cut or diamond cut burr which are well suited for most applications. However, there are numerous other geometry burrs to pick from which may aid performance in various applications:

Single cut carbide burrs:

These feature a single right-hand spiral flute and so are most commonly utilized on ferrous materials including cast iron or non ferrous materials including copper, brass and aluminium. They feature faster cutting with minimal built up edge, however the disadvantage is that they pull up in one direction therefore driving them to harder for the operator than a double cut burr.

Double cut carbide burrs

The most used and straightforward to use geometry for ferrous metals like carbon and alloy steels or soft stainless steels. The feature right and left handed cutting angles (cross cut style) and can produce a good surface finish compared to single cut burrs. A downside of the double cut burr is created up fringe 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.

Stainless cut (Inox-Cut) carbide burrs

It provides a powerful grinding giving Thirty-five percent more stock removal when compared with conventional burr geometry and reduced heat develop in the innovative 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 varieties of Carbide rotary burr are single cut and double cut.

The cut, that’s ideal for most ferrous metals, offers a faster cut with minimal clogging. The only cut incorporates a single right hand spiral flute.

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