What holds workpieces during high-volume drilling operations?

• A. Bench clamps
• B. Pilot pins
• C. Drilling fixtures and jigs
• D. V-Blocks

Answer: (C)

High-volume drilling needs a setup that locates each part precisely and holds it securely for every hole, cycle after cycle. Drilling fixtures and jigs are built for that purpose. They provide dedicated locating features to place the workpiece in exactly the same position every time and a clamping system to keep it from moving while the drill penetrates. This combination delivers repeatable hole locations, faster changeovers, and less variation caused by human handling, which is essential for production runs.

Bench clamps are general-purpose and meant for securing parts on a workbench, not for rapid, repeatable positioning in a dedicated production setup. Pilot pins help with locating the part in the fixture but don’t supply the necessary locking force to hold the part during drilling. V-blocks are great for holding round stock for certain operations, but they’re not designed to fix and align many different workpieces for a high-volume drilling process.
