Drill Bits: What You Need to Know

Drill bits, also referred to as boring heads or cutting tools, are essential for creating holes in wood, concrete, metal, and drywall. This collection ranges from compact 1/8-inch tips to extended 18-inch lengths, covering both standard and specialized jobs. Select models feature ultralight designs that reduce fatigue and improve handling during repetitive or overhead drilling.

Type:

  • Auger Bits: Designed for deep, clean drilling in wood. Commonly used in framing, carpentry, and utility installs.
  • Bit Holders & Extensions: These heads extend reach and accessibility in tight or recessed areas. Ideal for flexible and extended drilling tasks.
  • Coring Drill Bits: Create large-diameter holes in masonry or concrete. Used for pipe passages and HVAC installations.
  • Countersink Bits: Used to create a flush seating for fasteners. Helps prevent material splitting in wood or metal surfaces.
  • Drill Bit Combination Sets: Includes a mix of standard and specialty bits for broad application coverage. Best for general-purpose work and toolkits.
  • Hole Saws: Engineered for cutting wide openings. Frequently used for junction boxes, recessed lighting, or pipe access.
  • Masonry Drill Bits: Reinforced tips handle dense materials like brick, block, and stone. Built for durability and minimal wear.
  • Screwdriver Bits: Attach to drills for fastener driving. Used in framing, cabinetry, and general construction.
  • Spade Drill Bits: Flat-headed bits for wide, shallow holes in wood. Common in rough carpentry and deck building.
  • Specialty Drill Bits: Include uniquely shaped heads for non-standard cuts. Used in niche trades and detailed projects.
  • Step Drill Bits: Allow for multiple hole sizes with one bit. Especially effective on thin metal and plastic sheeting.
  • Twist Drill Bits: Versatile, spiral-headed bits used across wood, metal, and plastic. The most common type for everyday drilling.

Drills Applications:

  • Wood: Drill bits designed for wood include spade, auger, and twist types. These bits deliver fast, clean cuts for framing, carpentry, and general construction.
  • Concrete & Masonry: Masonry and coring bits are engineered to handle hard materials like brick, block, and poured concrete. They feature durable tips to prevent early wear.
  • Metal: Twist and step bits for metal applications provide accurate, burr-free holes in sheet metal and structural steel. Step bits are especially useful for variable hole sizing.
  • General Purpose: Combination sets, screwdriver bits, and extensions cover a range of light to heavy-duty drilling and fastening tasks. Great for contractors and DIYers alike.

Size:

  • Small (1/8 in – 1/4 in): These compact sizes are ideal for pilot holes, light fastening, and precision drilling. Commonly used in cabinetry, trim work, and detailed metal fabrication.
  • Medium (5/16 in – 1/2 in.): Standard sizes for general-purpose drilling in wood, drywall, and masonry. They provide balanced control and cutting strength for most routine tasks.
  • Large (9/16 in – 1 in+): Larger diameters suited for wide openings, structural penetrations, and high-demand drilling. Frequently used in plumbing, framing, and conduit installations.
  • Extended Length (6 in – 17-1/2 in): Long bits provide deep reach through thick or layered materials. Ideal for overhead work, in-wall drilling, or drilling through subflooring and joists.
  • Multi-Piece Sets (5-piece to 10-piece): Drill bit kits include assorted diameters and lengths for jobsite versatility. A practical option for contractors, remodelers, and maintenance crews.
