SJ-5 60° Countersink Premium Tungsten Carbide Burr

Carbide Countersink Burrs

I have a homebased machine shop and I felt these items would be very useful for countersinking and also deburring machined holes in steel. The carbide construction should keep these sharp for a long time.

Worked Great!

Better than expected. Held up to over 20 holes in 3/8 hardened plate and still cutting. Will purchase again.

Good quality and a low price

Used it a couple times already and works great and seems like will last.
