What are the types of carbide rotary burrs?
Carbide rotary burrs are tools used to remove burrs from hard materials such as ceramics, stone, steel, aluminum, plastics and hardwood. They provide precision and can also be used for cutting, shaping, grinding and chamfering hard materials. Tungsten carbide, historically known as Wolfram, after its discoverer, Peter Wilf, is commonly referred to simply as tungsten carbide; It is also known as hard alloy, solid hard alloy, hard metal, and sometimes tungsten. Tools made of carbides, such as burrs, can withstand higher temperatures and keep cutting edges sharper than high-strength steel. There are different kinds of carbide rotary burrs for different tasks, including 13 common burr shapes and 7 common burr flute styles. The shank is a burr mounted on a rotary tool, grinder, etc.
Carbide rotary burrs (cutters) are used to remove burrs (finish and smooth rough edges) from most hard materials such as ceramics, stone, steel, aluminum, plastics and hardwood. They provide precision. Commonly referred to simply as carbide tools, such as burr, carbide rotary burrs are made from carbides that can withstand higher temperatures and maintain a sharper cutting edge than high-strength steel. Carbide burrs are used for cutting, shaping, grinding and removing sharp edges, burrs and excess material (deburring). The decision to use what shape will depend on the outline or cut you want to achieve.
Carbide rotary burrs are usually available in three standard flute styles: single, double, and colored. However, there are several other varieties of flute styles, including fine, rough, diamond, crusher, cast cutting, omega cutting and more.
Single carbide rotary burr is mainly used for groove making, milling and cleaning. Single cut burr produces long chips and is ideal for heavy duty removal.
Double-slotted carbide rotary burr produces small chips and good finish, and effectively removes stock in hard materials. Additional flutes reduce pull and increase operator control. It is most suitable for medium to light removal. It can be used at a slower than normal speed.
Nonferrous flaut-style carbide rotary burr, sometimes called rapid mill cutting, is designed for rapid inventory removal with minimal chip loading, and is primarily used in plastics, zinc, and aluminum.
Fine-cut flute-shaped carbide rotary burrs are commonly used and create an excellent finish of hard material.
Rough-slotted burrs remove quickly and provide large groove areas on softer black and non-ferrous materials.
Crumb groove carbide rotary burrs are designed for rapid burr removal and provide better control, reduced sliver size, but slightly reduced surface finish.
Diamond cutting flute carbide rotary burr is mainly used to provide superior controlled heat treatment and tough alloy steel, and to produce powdered chips. Fiberglass burrs are a seed type of diamond cut burrs designed to remove medium stocks of fiberglass, composites, and carbon. Some manufacturers use double cutting and diamond cutting alternately.
Omega cutting groove type carbide rotary burrs, sometimes referred to as deep double incisions, have negative front angles for aggressive cutting, and have stronger teeth that provide longer life and less damage during HD work.
