Drills and countersinks may be held in a jig.

• A. True
• B. False
• C. Only some drills
• D. Only countersinks

Answer: (B)

Jigs are designed to guide the cutting tool while the workpiece is held in place to ensure repeatable, accurate holes. A drill jig uses bushings or guides to align the drill to the exact spot, but the cutting tool itself is still held by the drill press or by a hand-held tool, not gripped inside the jig. The same idea applies to a countersink: the jig can guide the countersink’s position, but the countersink is not clamped inside the jig as a part of the tool setup. So while a jig helps align drilling or countersinking, it does not hold the drill or countersink itself. That’s why the statement is not correct.
