This the wedge part of the right angle cylindrical tool adapter / carrier I made for the Dremel 220 Drill Press. This carrier needs the other parts (Mandrel, Lock Bar & Carrier) to function as per design.
Like most wedges it can also be used for jamming doors & propping things up. However its not good for separating objects as it has a blunt nose and grip surface.
When used as a back-to-back pair it locks on itself due to the design of the grip surface (this is how it locks the Dremel tool carrier mandrel in the carrier).
The Dremel 220-225 adapter is at the following link.
The wedge is 80mm long x 35mm wide. The thin end is 2mm high, the thick end is 6mm high.
