SN-4 Inverted Cone Premium Tungsten Carbide Burr

Love these for casting clean up!

These bits are a no brainer.

Like everything else they sell. . . A no brainer. Bits are fair priced and wear well. I have several and pleased with them all

Surprisingly awesome!

so.. in the past, burrs with hard, sharp edges (especially those with deeper angles than 90) have not kept their shape very long. The sharp edge chips, and then the burr is either dull, or overly aggressive. I've been pretty gentle with this edge, trying not to chip it, but I use it more and more in my metal sculpture to get deep into detailed troughs and to make lines. I've even bought another 45 degree pneumatic die grinder for it, so it has a permanent home. Its still pretty new, but holding up well, and really useful for my detail work! --- in fact, Ive been waiting long for a quality burr, with this inverted shape, to be produced. When I kill it, I'll buy another. Thank you BenchMark. You are becoming my primary go to. Jacob Dean Metal Sculptor. I love the ceramic cutoff wheels too!
