What is the wedge device that holds a router bit in place called?

• A. Base plate
• B. Shank
• C. Collet
• D. Fixture

Answer: (C)

The thing that actually grips and holds a router bit in place is the collet. It’s a tapered, slotted sleeve inside the router’s chuck that surrounds the bit’s shank. When you tighten the collet nut, the collet contracts around the bit, gripping it firmly and preventing any pullout or rotation. The bit’s shank is just the part that fits into the collet, not the gripping mechanism itself. Base plate is the router’s bottom plate used for guiding and stability; a fixture is any device used to hold work or tools, not the tool that grips the bit. Collets come in different sizes (like 1/4" or 1/2") to match the bit shank and ensure a secure fit.
