COBALT STEEL PERFORMANCE
Warrior Cobalt Steel Drill Bit Set
★ 4.5 · 342 reviews
When your project hits hardened steel or stainless, ordinary bits just skate across the surface. This Warrior set is built from HSS with 5% cobalt content, giving each bit the heat resistance and edge retention to punch through tough metals without losing its temper. The 135-degree split-point tips bite on contact-no walking, no pilot holes needed on sheet metal-and the cobalt blend keeps cutting even when…
- 5% cobalt HSS construction withstands extreme heat and resists wear on hard metals like stainless steel and cast iron
- 135-degree split-point geometry eliminates walking and starts holes cleanly without a center punch
- 29-piece set covers 1/16" through 1/2" in 1/64" increments for complete workshop coverage
- Fully ground flutes with gold oxide finish improve chip evacuation and extend bit life
- Durable metal index case with size markings keeps bits organized and protected in transit
SELECTION GUIDE
Choose Your Perfect Bit in Three Simple Steps
Picking the right drill bit from Harbor Freight doesn’t require an engineering degree. Follow these three practical steps to match a bit to your project, material, and tool setup-saving time, money, and frustration.
Target Material
Wood bits, masonry bits, and metal bits use different flute patterns and tip grinds. Confirm your workpiece material first-it drives every other decision.
Bit Diameter
Match the hole size to your fastener. Undersized bits cause splits; oversized bits reduce holding power. Harbor Freight labels list exact fractional and metric sizes.
Shank Compatibility
Round, hex, and SDS shanks fit different chucks. A round-shank bit wobbles in an impact driver’s collet. Verify your drill’s chuck type before checkout.
Coating & Finish
Black oxide, titanium nitride, and bare high-speed steel each offer different heat resistance. Longer drilling sessions in metal call for coated bits that stay sharp under friction.
Set vs. Individual
Buying a 29-piece index set covers common sizes, but you may only need two or three diameters. Individual bits cost less upfront if your project scope is narrow.
Drill Speed & Torque
High-speed steel bits tolerate faster RPM than cobalt or carbide-tipped versions. Match your cordless drill’s speed settings to the bit manufacturer’s recommended range.
Bits for the Jobs Others Can't Handle
When standard bits fail on brittle tile or thick lumber, these specialized options step in.
Warrior Glass & Tile Bit
Carbide tip grinds through porcelain and ceramic without cracking, so your backsplash stays intact.
Warrior Spade Bit Set 6-Piece
Fast, rough holes in dimensional lumber for running cable or pipe-no pilot hole required.
Warrior 1/2 in. Masonry Bit
Hammer-drill rated carbide tip punches anchor holes in concrete block and poured foundation walls.
Warrior Bi-Metal Hole Saw Kit 7-Piece
Cut clean, oversized holes in thin metal, plastic, and drywall for electrical boxes or pipe runs.
Warrior Countersink Bit Set 3-Piece
Drill and countersink in one pass so screw heads sit flush with wood surfaces every time.

COST COMPARISON
Harbor Freight Drill Bits: The Price vs. Performance Tradeoff
We break down how Harbor Freight drill bits stack up against national brands in the $5 to $50 range, focusing on what your money actually gets you.
Entry-Level Pricing Under $10
Basic steel bit sets from Harbor Freight start around $5, making them ideal for one-off projects or materials where frequent replacement is expected. A comparable entry set from a national brand like DeWalt often runs $15 to $25 for a similar piece count.
Mid-Range Sets from $15 to $30
This is where Harbor Freight’s Warrior and Drill Master lines compete most aggressively. You get titanium-coated or black oxide bits in organized cases. The performance gap versus $30 to $50 national-brand sets narrows noticeably for wood, soft metals, and general construction tasks.
Premium Tier Under $50
Harbor Freight’s top-tier drill bit sets, often under $40, include cobalt and carbide-tipped options. While a Milwaukee or Bosch equivalent might cost $60 to $80, Harbor Freight’s versions handle hard metals and masonry adequately for most non-production work.
Warranty Coverage Included
Every Harbor Freight drill bit set comes with a 90-day warranty against defects. National brands typically offer a limited lifetime warranty, so there’s a clear tradeoff: you save upfront but have less long-term protection if a bit fails under normal use.
No-Frills Packaging
Harbor Freight drill bits come in simple blister packs or basic plastic cases, not the molded, magnetic-lid containers some competitors use. This keeps costs down, but you’ll want to transfer bits to your own organizer for workshop storage.
Ready Stock at 1,400+ Locations
Unlike some national brands that require ordering online or visiting a specialty store, Harbor Freight keeps drill bit sets in stock at over 1,400 US stores. Need a replacement set on a Saturday afternoon in a pinch? You can grab one off the shelf same day.
Your Top 5 Drill Bit Questions, Answered
Get straight answers to the most common questions about choosing, using, and maintaining Harbor Freight drill bits.
- Can I use a metal drill bit on woo
- How do I sharpen a dull drill bit
- What size drill bit do I need for
- How long should a drill bit last
- What does the gold-colored coating
You can, but it’s not ideal. Metal bits have a steeper point angle designed to cut through steel, which can cause them to wander or split wood fibers rather than slice cleanly. For the cleanest holes in lumber, plywood, or MDF, use a brad-point or spade bit. Keep a dedicated set for each material to save time and get better results.
A bench grinder is the quickest fix. Hold the bit at its original factory angle-usually 119 degrees for general-purpose bits-and lightly touch each cutting edge to the wheel for a second or two, keeping the motion even. For smaller bits, a simple drill bit sharpener jig that clamps to your workbench takes the guesswork out of the angle. Replace bits that are chipped, deeply worn, or shorter than 2…
For a #8 screw, use a 7/64-inch bit for hardwood and a 1/8-inch bit for softwood like pine. These pilot hole sizes let the screw threads grab firmly without splitting the material. If you’re driving into end grain or very dense oak, bump up one sixty-fourth to avoid snapping the screw.
A high-speed steel bit in regular use should drill several hundred holes in wood or soft metal before needing replacement. Harder materials like stainless steel or concrete wear bits faster-expect 50 to 100 holes in masonry with a carbide-tipped bit before the edge dulls noticeably. Storing bits in a case rather than tossing them loose in a toolbox extends life significantly, since dinged edges cut poorly even…
That titanium nitride (TiN) coating reduces friction and heat buildup, so coated bits stay sharp roughly three times longer than plain high-speed steel in identical use. The tradeoff: you can’t resharpen coated bits without stripping the coating off the cutting edge, at which point they perform like an uncoated bit. For one-off projects, a standard bit makes more sense; for repeated drilling in metal, coated bits…
Almost all consumer drills use a standard three-jaw chuck that accepts round shanks from 1/16 inch up to 1/2 inch. Larger bits-like 1-inch spade bits or auger bits-often have a 1/4-inch hex shank that also fits impact drivers. SDS-plus hammer drills require a specific shank design for masonry work, so check your chuck type before buying specialty bits.
