Silver & Deming Drill Bit Set: 9/16 to 1-1/2 Sizes Guide

Quick answer

For drilling large holes (9/16 to 1-1/2 inches) in metal with a standard 1/2-inch chuck drill, the Drill Hog 16-piece Silver & Deming set in hi-molybdenum M7 steel is a durable, cost-effective choice.

Decision rules for choosing a Silver & Deming set

• Check your chuck capacity: Most handheld drills have a 1/2-inch chuck. The reduced shank on these bits fits that chuck, so you don't need a larger drill.
• Match steel type to your material: For mild steel, aluminum, and stainless up to 1/4-inch thick, hi-molybdenum M7 works well. For harder alloys or deep holes, consider cobalt or carbide. If you mostly drill mild steel, M7 saves money without sacrificing performance.
• Count the sizes you actually need: The set covers every 1/16-inch increment from 9/16 to 1-1/2. If you only need three or four sizes, a custom pack might be cheaper. If you regularly need a range, the set is more economical. List your common hole sizes before buying.
