Crain 530 Rubber Base Gouge

This tool for gouging out the back of rubber or vinyl base for tightly-wrapped corners comes with a double-tipped blade. The V-tip makes a sharp V-shaped groove that conforms better to tightly formed sheetrock corners. The U-Tip makes a wider U-shaped groove for fuller corners, or for tougher base where a wider groove must be made. The depth gauge adjusts using a simple set screw.
