FAQ

What is the difference between double cut and non-ferrous carbide burrs?
Double cut burrs cut on steel, stainless and cast iron and leave smaller chips and a smoother finish. Non-ferrous (aluminum cut) burrs have fewer, wider flutes that clear soft metals such as aluminum, brass and copper without loading up.

When should I use a mounted point instead of a carbide burr?
Abrasive mounted points grind and blend rather than cut, so they are better for finishing welds, smoothing castings and working hardened material. Carbide burrs remove material faster and keep a sharper profile.

What speed should I run a carbide burr at?
Most 1/4 inch shank carbide burrs run well between 15,000 and 30,000 RPM on a die grinder; larger head diameters need lower speeds. Never exceed the maximum RPM marked on the package.

Why use a 6 inch long shank burr?
Long shank burrs reach deep into castings, pipe and assemblies where a standard 2 inch shank cannot, while the die grinder body stays clear of the part.
