Best High-Quality Drill Bit Sets for Wood, Metal, and Everyday Projects
The best high-quality drill bit set depends on the materials you drill and the size range you need. For general household and workshop tasks, the DEWALT 21-piece black-and-gold set covers several common materials. The DEWALT titanium nitride set is suited to cleaner starts in wood, metal, and plastic, while Drill America’s 29-piece cobalt set is aimed at acrylic, steel, and harder metals.

DEWALT DW1361 Titanium Nitride Set
Best for: Buyers who want a versatile set for wood, metal, and plastic, with features intended to help bits start cleanly. It includes 21 bits in a case and uses a titanium nitride coating, pilot point, and no-spin shanks.
The pilot point is designed to start on contact for cleaner holes. The no-spin shanks are intended to help keep bits from turning in the chuck. These details make this set a practical choice for users who value controlled starts across common materials.
Limitation: The listed features do not provide a size-by-size inventory, so check the set’s size range before buying if a particular diameter is essential.
Drill America KFD29J-PC HSS Set
Best for: Users who need a wide selection of fractional-inch sizes for varied drilling jobs. This 29-piece jobber-length set ranges from 1/16 to 1/2 inch in 1/64-inch increments.
The bits are made from high-speed steel, which the product information describes as providing hardness for wear resistance. A black-and-gold oxide finish is specified to resist corrosion and increase bit hardness. The round case keeps the assortment together for storage.
Choose this set if having fine size increments matters more than a feature-rich point design. Limitation: The listing describes a general HSS set; it does not identify it as a cobalt set for hardened metals.
DEWALT DWA1184 Split-Point Set
Best for: Buyers seeking a compact, 14-piece set for plastic, wood, and metal. Its 135-degree split-point tip is designed to help reduce walking when starting a hole.
The bits use high-speed steel, and the tapered web design is specified to improve durability and resist breakage. This set is a better fit for someone who wants a smaller assortment and values a split-point design over having the largest number of sizes.
Limitation: At 14 pieces, it offers fewer bits than the 21- and 29-piece options here. The provided details do not list its individual sizes.
Drill America ZMGSC29J-PC Cobalt Set
Best for: Users drilling acrylic, steel, brass, and other hardened metals who want an assortment from 1/16 to 1/2 inch in 1/64-inch increments. Its cobalt stepped-point design has a 135-degree split point, and the product listing says it can create new holes or enlarge existing ones.
The jobber-length bits have a gold oxide finish and a three-flat shank intended to help prevent spinning. Bits 11/64 inch and smaller have round shanks. The manufacturer describes the stepped-point design as starting easier and reducing heat compared with standard bits.
Limitation: The shank style varies by size, so check that detail if a consistent three-flat shank across the set is important.
DEWALT DWA1181 Black Oxide Set
Best for: General-purpose drilling in metal, hardwood, softwood, PVC, and fiberglass. The 21-piece set uses high-speed steel bits with a black oxide coating that the listing says helps resist corrosion and increase durability.
A parabolic flute design is specified to improve chip ejection during drilling in metal and wood. This makes the set a straightforward choice for buyers who want one assortment for several common materials and value chip removal as a listed design feature.
Limitation: The product information does not give a complete size list here. Confirm that the included diameters match your project before choosing it.
Buying Guide: How To Choose A Drill Bit Set
Which materials will you drill?
Match the set to your most frequent work. The DEWALT options list wood, metal, and plastic or other common materials. The Drill America cobalt set specifically names acrylic, steel, brass, and hardened metals. Do not assume every set is suited to every material just because it contains metal-drilling bits.
How many sizes do you need?
A larger piece count can provide more size choices, but count alone does not tell you whether a required diameter is included. The KFD29J-PC and ZMGSC29J-PC listings specify a 1/16-to-1/2-inch range in 1/64-inch increments. For other sets, verify the individual size list before purchase.
Does the point or shank design matter?
A split point is intended to help reduce walking at the start of a hole. A pilot point is designed to start on contact. Shank features such as no-spin or three-flat designs can help resist spinning in the chuck. Choose based on the feature that addresses your work, and note when a set uses different shanks for smaller bits.
What do coatings and flute designs tell you?
Coatings and flute shapes are useful comparison points, not guarantees of performance in every setup. These listings describe titanium nitride, black oxide, and gold oxide finishes, plus a parabolic flute designed for chip ejection. Follow appropriate drilling practices for the material and bit.
Frequently Asked Questions
What is a good all-purpose drill bit set?
A set listing several common materials is a reasonable starting point. The DEWALT DWA1181 is described for metal, hardwood, softwood, PVC, and fiberglass.
Which set has the widest specified size range?
Both Drill America 29-piece sets list sizes from 1/16 to 1/2 inch in 1/64-inch increments.

The Drill America ZMGSC29J-PC is the set in this selection specifically described for steel and other hardened metals, along with acrylic and brass.
Do split-point bits help prevent walking?
The DEWALT DWA1184 listing says its 135-degree split-point design helps reduce walking. Actual results can depend on the material and drilling technique.
Should I choose more pieces or a specialized set?
Choose more pieces when size variety is the priority. Choose a specialized set when its material, point, coating, or shank features better match the work you perform most often.
