Wood Drill Bit Sets

Match the bit type to the task: brad-point bits and spur-point bits give clean, precise holes in soft and hardwood; auger bits are best for deep, through-holes; Forstner bits create flat-bottomed holes for cabinetry; and spade bits are economical for rough, large-diameter holes

Choose a set that covers the hole diameters you commonly need; common ranges are small fractional or metric sets (1/16"–1/2" or 1–13 mm) for finish work, and sets that include larger sizes or 1/4" hex shanks for structural work. Also consider whether you need individual large-diameter Forstner, auger, or spade bits in addition to smaller twist-style bits

HSS bits provide better wear resistance and heat tolerance than plain carbon steel; coatings like black oxide or titanium nitride can extend life and reduce friction, especially when drilling hardwoods or drilling frequently, but they won't change cutting geometry, so choose based on expected use and budget

Check shank type and diameter—round shanks fit keyed chucks, reduced or hex shanks fit quick-change chucks—and ensure the drill has sufficient speed and power for the bit size; larger-diameter bits and Forstner or auger bits perform better with cordless or corded drills that provide higher torque

Keep bits sharp by honing with a flat file or diamond sharpener when needed, remove pitch buildup with solvent, store in a case to avoid damage, and use proper drilling speed, steady feed pressure, and pilot holes for large diameters to reduce wear and prevent chipping

Use higher speeds for softwoods and smaller-diameter bits, lower speeds for hardwoods and large-diameter bits; use backing support to prevent tear-out, drill at moderate steady pressure, and clear chips frequently with auger bits to avoid binding and overheating

Prices vary by bit type, material, and set size; general-purpose starter sets often start under $25, mid-range HSS or coated sets commonly range from about $25 to $100, and larger specialty sets or premium materials can cost more
