SC-5 Tungsten Carbide Burr Rotary File Cylindrical Shape with Radius End Double Cut with 1/4''Shank for Die Grinder Drill Bit

I use it to help clean up burls for epoxy pours prior to turning. Works great. Value is perfect. Seems that the sharpness is long lasting and cuts quickly.I will probably buy a couple other models so I can have a variety of these. Great purchase for me.

Appears to be carbide as described. Used to bore a channel through fire brick to run heating element for a heat-treat oven. The nature of that material would very quickly destroy anything other than carbide; the bit did its job efficiently.

Unlike the burrs available at the discount box stores, this burr seems a lot tougher. I haven't used it on metal, but I suspect it will last a while if not abused.

I BOUGHT THIS FOR A SPECIFIC JOB AND IT WORKED GREAT.

Definitely worth the money for the price , a little chewed up after the first use but did it’s job

Works great takes metal off like it should. Just dont get it to hot

Works as designed for a fraction of the cost of a known brand. Can’t say I use it all the time but has worked for me every time I’ve needed it.

Looks great right out of the package. I use it every day since I got it and it still cuts quickly and cleanly. Decent value, I'll definitely reorder when the necessity arises.
