Difference Between Carbide Burs
What is the Difference Between Carbide Burs?
The right carbide bur for your deburring, milling, cleaning and finishing applications depends on several factors. The size, shape, fluting style, and application all play a role, as does the material you’re cutting.
Solid carbide burs can handle most jobs, with long-shank carbide burs ideal for hard-to-reach areas and midget burs for the utmost accuracy.
Different Fluting Styles
The most common fluting style is double cut. With superb operator control and more cutting edges, double cut carbide burs remove material faster and create small chips, leading to a smoother finish. Perfect for steel as well as soft metals (ferrous and nonferrous) and non-metal materials, double cut flutes are the most popular for just about any application.
Single cut carbide burs use one flute to remove material quickly. Good for milling, deburring, cleaning and removing heavy stock, single cut carbide burs produce long chips and are reliable for a number of different materials, predominantly steel.
Diamond cut is specifically for heat-treated and tough alloy steels, when you need complete control, generating a powder-like chip and excellent finish.
For soft ferrous materials, coarse cut aggressively removes material using a large flute area.
When working with hard materials requiring a fine finish, a fine cut carbide bur is right for your application.
Available Sizes – When and Why to Use Them
Falcon solid carbide burs come in 1/8” and 1/4” shank options to fit your pneumatic tool, with multiple available lengths. A standard 1.5” length is good for most applications, but for hard-to-reach or tight areas, you may need to step up to 2”, 3”, or even an extra-long shank.
Falcon midget carbide burs have a 3/32” shank with a 1.75” length to maximize control and efficiency as you work on projects that demand precision and accuracy.
Carbide burs are also available in many different shapes to handle any grinding application. No matter what your task, there’s a size and shape combination to get the job done.
Pieces of Equipment to Use with Various Carbide Burs
Carbide burs work best in pneumatic tools. Die grinders, high-speed engravers, rotary tools — any type of air tool you can control reliably. That is, a tool that won’t wobble and likely has a handpiece for stability.
