A set with every 1/32-inch step from 1/16 to 1/2 inch includes 15 sizes, including 1/8, 3/16, 1/4, 5/16, and 3/8 inch. Those are the sizes that come up repeatedly for pilot holes, wall anchors, brackets, hooks, and basic hardware.
Start With Your Next Few Projects
Before buying, look at the jobs already waiting around the house. Hanging shelves, assembling furniture, and mounting curtain brackets call for different bits than drilling brick for masonry anchors.
Use this quick guide:
- Shelves, blinds, hooks, and brackets: Buy HSS twist bits and match the hole size to the wall anchor instructions.
- Furniture assembly and small wood repairs: Start with HSS twist bits. Add brad-point bits later when clean holes in visible wood matter.
- Brick, block, mortar, or concrete anchors: Buy carbide-tipped masonry bits in the sizes required by the anchors.
- Large holes for pipes, wiring, or door hardware: Add spade bits or hole saws separately.
- Ceramic, porcelain, or glass tile: Use a bit made for that surface. A general twist-bit set is not the right tool for tile.
A large mixed kit can look like a bargain, but piece count is often less useful than a complete run of common sizes. A smaller, organized set with the right bit type will serve you better than a case full of duplicate driver bits and accessories you never use.
Drill Bit Types That Matter
Bit style matters as much as diameter. A sharp-looking bit with a dark or gold finish is not automatically suitable for every surface.
| Bit type | Best use | Choose it when | Skip it when |
|---|---|---|---|
| HSS twist bit | Wood, plastic, and light metal | You need a general household set for pilot holes, hardware, brackets, and many everyday repairs. | You need especially clean holes in finished wood, masonry drilling, or tile work. |
| Brad-point bit | Clean holes in wood | You are drilling visible cabinet faces, trim, furniture parts, or other finished wood. | You need to drill metal, masonry, or plastic. |
| Carbide-tipped masonry bit | Brick, block, mortar, and concrete | You are installing masonry anchors or drilling into a hard mineral surface. | You are drilling wood, metal, or finished tile. |
| Spade bit | Fast rough holes in wood | You need larger openings for wiring, pipes, or rough carpentry. | You need a clean exit hole in finished wood. |
| Hole saw | Large circular openings | You are cutting openings for pipes, cable runs, locks, or hardware. | You only need ordinary pilot holes and small hardware holes. |
| Tile or glass bit | Ceramic, porcelain, and glass | You need to drill a finished tile surface without using a standard twist bit. | You are drilling ordinary wood, drywall, or metal. |
For a first tool drawer, HSS twist bits provide the broadest coverage. They work for many household tasks, but they are not the cleanest option for stained trim, cabinet faces, or furniture-grade woodworking.
What to Spend Money On
Put your budget toward three things: complete size coverage, readable markings, and a case that keeps every bit in place.
An indexed case is more useful than a huge accessory count. When each bit has a labeled slot, you can quickly grab the 3/16-inch or 1/4-inch size instead of sorting through loose steel bits covered in dust and chips.
A compact set suits occasional repairs and small storage spaces. A larger set makes sense when you regularly work on projects that call for more sizes or more than one material.
Avoid paying extra just for coatings, color, or a crowded kit. The material of the bit, the available diameters, and the organization of the case have a bigger effect on whether the set helps with actual home projects.
Pick a Set by Use Case
For Wall-Mounted Shelves and Décor
Buy for the anchor first. The anchor package should state the required hole diameter, and your bit set needs that exact size.
A hole that is too small can make the anchor difficult to insert. A hole that is too large can leave the anchor loose in the wall. Do not choose the drill bit by comparing it to the screw alone.
For Furniture and Softwood Repairs
Start with HSS twist bits for pilot holes, hardware holes, and general repairs. They are the most flexible choice for a beginner building a basic set.
Add brad-point bits when you begin drilling holes that will remain visible. Their center point helps keep the bit from wandering on wood surfaces and produces a cleaner entry hole.
For Brick, Block, and Concrete Anchors
Keep a separate carbide-tipped masonry bit set for these jobs. Masonry drilling creates abrasive dust, and the bit diameter must match the anchor instructions.
Use hammer mode only when both the drill and the bit are intended for masonry work. Keep hammer mode off for wood, metal, plastic, and finished tile.
For Large Holes
Do not buy an oversized twist-bit kit just to cover a few large openings.
Use a spade bit for rough holes in wood, such as openings for cables or pipes. Use a hole saw for larger circular openings where the shape and edge quality matter more. These tools solve a different problem than a standard twist-bit set.
For an Impact Driver-Only Setup
Choose impact-rated hex-shank drill bits if your only drilling tool is an impact driver with a 1/4-inch hex collet.
Round-shank bits are intended for a drill chuck. Hex-shank bits can be used in a drill chuck and in a compatible impact-driver collet.
Size, Setup, and Compatibility
A drill bit’s cutting diameter and shank diameter are not always the same. The shank is the part held by the drill chuck, so that is the measurement that determines whether the bit fits your drill.
Keep these points in mind:
- Chuck capacity: A 3/8-inch chuck accepts shanks up to 3/8 inch. A 1/2-inch chuck accepts larger shanks.
- Set range: A 1/16- to 3/8-inch fractional set covers many common household holes. Extend to 1/2 inch when you expect larger work and your drill can hold the included shanks.
- Shank style: Round shanks fit drill chucks. Hex shanks fit drill chucks and 1/4-inch hex impact-driver collets.
- Bit length: Flute length, rather than overall length, affects useful drilling depth and chip clearance.
- Anchor size: Follow the hole diameter printed on the anchor package.
- Drill mode: Use hammer mode only for supported masonry work.
Fractional sizing is especially useful for household repairs because many anchors and hardware instructions use inch measurements. Metric markings are helpful, but near-equivalent sizes are not interchangeable when an anchor or precision hardware calls for a specific hole diameter.
Maintenance and Storage
Return each bit to its labeled slot after it cools. This keeps the sizes readable and prevents the case from turning into a pile of loose bits.
Clear wood chips, drywall dust, and metal shavings from the work area with a brush or vacuum. Do not sweep sharp metal shavings with bare hands. Keep masonry dust out of the bit case, since it can coat the bits and make small sizes harder to identify.
Wipe off resin, adhesive residue, and damp debris before putting bits away. Replace snapped bits and bits with visibly damaged tips. Small twist bits are difficult to sharpen accurately, so replacing a damaged small bit is usually simpler than trying to restore it.
OSHA’s hand and power tool guidance is a useful safety baseline for eye protection, safe tool handling, and keeping the work area under control.
Who Should Skip a General HSS Starter Set
Skip a general HSS set as your only purchase when one specialized job is driving the purchase.
Tile installation calls for tile-rated bits. Repeated concrete anchoring calls for carbide-tipped masonry bits. Cabinetmaking and finish carpentry benefit from brad-point bits, Forstner bits, and other clean-cutting woodworking tools.
Also skip a giant mixed-accessory bundle when storage is already limited. A smaller indexed HSS set plus one job-specific bit type is easier to organize and easier to use.
Before You Buy
Use this checklist before adding a drill bit set to the tool drawer:
- Confirm your drill’s chuck capacity.
- Choose fractional sizes from 1/16 through at least 3/8 inch.
- Add 1/2-inch coverage when your drill accepts the included shanks and you expect larger holes.
- Look for engraved or clearly stamped size labels.
- Choose an indexed case with a dedicated slot for each bit.
- Match one specialty bit type to the next material-specific project.
- Match wall-anchor holes to the diameter stated on the anchor package.
- Keep tile, masonry, and large-hole tools separate from the starter twist-bit set.
Common Buying Mistakes
Buying by Piece Count Instead of Size Coverage
A set with 15 useful fractional sizes is often more helpful than a larger case packed with duplicate screwdriver bits and unrelated accessories.
Using a Screw as the Pilot-Hole Measurement
Pilot-hole size depends on the screw, the material, and whether the hole needs thread grip or clearance. Use the fastener maker’s instructions for structural hardware and specialty fasteners.
Forcing a Dull Bit Through Material
Too much pressure creates heat, dulls the cutting edge faster, and can snap smaller bits. Stop when the bit stops cutting cleanly, clear the chips, and replace a damaged bit.
Drilling Blindly Into Walls
A stud finder and awareness of plumbing and wiring routes matter before drilling into drywall. The correct bit cannot prevent damage from a hidden utility.
Using Hammer Mode on Finished Surfaces
Hammer action is for supported masonry drilling. It can damage wood fibers, metal surfaces, and tile.
Bottom Line
A first-time buyer should start with an indexed HSS fractional twist-bit set covering 1/16 through 3/8 inch, then add 1/2-inch coverage when larger holes are part of the plan and the drill accepts the set’s shanks.
Buy carbide-tipped masonry bits for brick and concrete, brad-point bits for clean wood holes, tile-rated bits for ceramic or porcelain, and spade bits or hole saws for large openings. Clear markings, a well-organized case, and the correct bit for the material matter more than a massive accessory count.
FAQ
What drill bit sizes does a first-time homeowner need?
A range from 1/16 to 3/8 inch handles many basic household repairs, including pilot holes, small hardware, brackets, and common wall anchors. Extend to 1/2 inch when you expect larger holes and your drill accepts the included shanks.
Are titanium-coated drill bits worth buying?
A coating does not replace correct bit material or proper use. HSS twist bits are the core choice for broad household drilling, while carbide masonry bits and brad-point wood bits handle more specific jobs. Clear size markings and a durable indexed case are usually more useful than a finish color.
What is the difference between a drill bit and a driver bit?
A drill bit removes material to create a hole. A driver bit turns screws. Many mixed kits include both, but a useful drill bit set should cover the hole sizes needed for anchors, pilot holes, and hardware.
Do I need masonry bits for drywall anchors?
No. Drywall anchors use standard twist bits when a pilot hole is required. Masonry bits are for brick, block, mortar, and concrete. Match the bit diameter to the anchor instructions.
How do I keep drill bits from rusting?
Keep bits dry, remove dust and debris before storage, and return them to a closed indexed case. Avoid leaving damp bits in a garage pouch or packing masonry dust around them.
