Which clamp is a deep-throated tool useful when other clamps are too small, particularly on the drill press?

• A. Quick Clamp
• B. Pipe Clamp
• C. Pocket Hole Jig
• D. Large C Clamp

Answer: (D)

When you need to clamp something in a space where other clamps won’t reach, the key is a deep throat—the distance from the screw to the body of the clamp. A large C clamp has a long screw and a roomy throat, so it can reach over the drill press table or around the column and still press the workpiece firmly against the surface. This makes it ideal for holding parts in place while you drill or position blocks near the drill press.

Quick clamps are handy but have a short throat, so they can’t reach deep around edges or around the drill press. Pipe clamps can reach far, but they’re bulkier and slower to set up. A pocket hole jig isn’t a clamp at all. So the large C clamp provides the necessary depth and holding power for these situations.
