This Tungsten Rod Sharpener / Grinder is a great tool to quickly and repeatedly cut-off and sharpen Tungsten Rods for TIG Welding. This attached to a Dremel 4000 (and other compatible versions) via screwing on to the Dremel's removal tip as shown.

It can sharpen angles of 15, 30, 45, and 60 degrees.

The four removable and interchangeable setscrews will be one of each for the following sizes, unless one requests differently at checkout. For those who only use one diameter rod, four identical screws can be provided, to remove the need to swap screw for different angles.
