Intro: Drill a hole lengthwise through a dowel. I am working on a project that requires that a through-hole be drilled lengthwise through a dowel. (The resulting tube will be used as a cam collar for ... 1. Step 1: Build a jig. Take a piece of scrap board, and a few inches from one end drill a hole the size of your dowel. (3/4 in my case.) Use a drill press if available, to ensure the hole is drilled perpendicular to the board. Saw a slot about 1/4 wide from one end of the board up to the hole. (I used a table saw to do so.)
The counterbore tool is typically a specialized drill bit that creates the hole for the body of the fastener and the larger sized cavity for its head, both at the same time. Usually, the fastener chosen is a flat-bottomed screw such as a round head or a pan head screw.sually, a socket wrench is used for the purpose, which means enough space must be available around the screw head to insert the socket wrench and allow it to grip the head of the fastener. For this, the counterbore cavity is drilled to a diameter larger than that necessary to accommodate the socket wrench.
