Cut a 2" hole in a piece of thin wood or hardboard on a drill press by using a hole saw or a frostner bit

• A. frostner bit
• B. brad point bit
• C. twist drill
• D. Forstner bit

Answer: (A)

Focusing on a clean, accurate large hole in wood on a drill press is best served by a bit designed for flat-bottom holes. A frostner bit, often called a Forstner bit, is made to bore precise, smooth-edged holes with a flat bottom. The center point helps start the cut precisely, and the cutting rims shave away material cleanly, which is especially helpful in thin stock like wood or hardboard where tear-out is a risk. While a hole saw can cut large diameters, it tends to leave rough edges and requires extra cleanup or a pilot setup. A twist drill or brad-point bit isn’t ideal for a 2" hole in thin material because they’re prone to wandering or producing rougher edges and aren’t optimized for large-diameter, clean, flat-bottom holes. So the frostner (Forstner) bit is the best choice for this task.
