For finishing and touch ups. This Bronze bound grinding tool is perfect to knock the sharp edges off a newly drilled hole so a cord or chain travels smoothly without bitting. It comes in the standard F-connection and fits the Multidrill, Gunther Hobby, and Gunther TBH II Professional systems.

The standard size is 8.0 mm X 5.0 mm/90°/D54, but we can make a custom size upon request. It has a built in water cooling system to be used with all Gunther drilling systems.

We typically keep several standard size grinding tools in stock and we anticipate a two-day turnaround for delivery. For custom orders, we should be able to deliver in 4 - 6 weeks.
