See The Difference Of Imitation Vs. Professional Carbide Burrs

When looking for a set of carbide burrs, you met with more options and price points today than ever. However, there is no cheap way to sinter, forge, machine and precision grind 100% raw virgin tungsten carbide burrs and shanks. When used as intended, professional carbide burrs can last a lifetime - see the difference.

Double Cut Design For Steel, Stainless, Iron & More

From soft mild steel to extra hard stainless welds and cast iron, the Astro 2181's tugsten carbide is designed to grind through it all.

Popular For Performance Gains

Increase the CFM & flow of iron cylinder heads, manifolds and more to unlock the breathing potential of your engine.

Chip Resistant Tooth Design

Astro uses a unique tooth angle and design that helps to avoid chipping, the cause of failure on extremely high hardness tungsten carbide.

Exactly like described.
5 Stars
Exactly like described.
Well balanced, cuts effortlessly in steel, iron and most other metals. Yes, even aluminum. Better surface finish on aluminum than aluminum specific carbide. If they ever load with aluminum or zinc, just clean with ammonia.The case is a little weak and the burrs may rattle out. These will live in my work truck which isn't exactly smooth riding. And often off road. But if they will live in your tool cabinet or bench, they are fine. To prevent the burrs from falling out and hitting each other, I put a single layer of double sided foam tape on the lid. This prevents the burrs from falling out when the lid is closed. Yes, the lid snaps closed securely. All is well now.
