When boring deep holes in wood, what practice helps clear wood chips?

• A. Drill slowly with the same depth
• B. Use a large bit
• C. Back the drill out often to clear the wood chips
• D. Keep the drill on until through

Answer: (C)

When drilling deep holes in wood, clearing the chips is essential to keep the bit cutting smoothly. Backing the drill out often ejects the accumulated wood chips, preventing them from packing around the bit, which can cause binding, heat buildup, and tear-out. By retracting the drill periodically, you improve airflow, reduce friction, and maintain a straighter, more accurate hole. A practical approach is to drill a short depth, then withdraw the bit a little to clear the chips, and repeat until you reach the desired depth.
