Facts About Tungsten Carbide Rotary Burrs

What are Tungsten Carbide Rotary Burrs?
ZhuZhou Apple Carbide Produced Tungsten Carbide Rotary Burrs, often referred to as rotary files or die grinder bits are used for cutting, shaping, and grinding, and for the removal of sharp edges, burrs and excess material (deburring).

What Materials could be used for Carbide Burrs ?
Tungsten Carbide Rotary Burrs can be used on a multitude of materials: metals including steel, aluminum and cast iron, all types of wood, acrylics, fibreglass and plastics. Carbide burrs are also perfect for working on softer metals such as gold, platinum and silver as they last a long time with no chipping or breaking.

Carbide Burrs Commonly Come in Two Cuts; Single Cut and Double Cut
Single cut (one flute) carbide burrs have a right handed (Up cut) spiral flute. These tend to be used with stainless steel, hardened steel, copper, cast iron, and ferrous metals and will remove material quickly. Use for heavy stock removal, milling, deburring and cleaning.

Double cut carbide burrs tend to be used on ferrous and non ferrous metals, aluminium, soft steel and also for all non-metal materials such as plastics and wood. They have more cutting edges and will remove material faster. These are the most popular cut and will see you through most applications.

Carbide Burrs are Harder than HSS Burrs
Good quality Carbide Burrs are machine ground from a specially chosen grade of carbide. Due to the extreme hardness of the Tungsten Carbide they can be used on much more demanding jobs than HSS (High Speed Steel).
Carbide Burrs also perform better at higher temperatures than HSS so you can run them hotter, for longer.
