Check Price on Amazon

The DEWALT DW1361 uses a pilot point tip that starts cutting on contact, eliminating the need for a center punch on most materials. This geometry difference — a sharpened web that creates a small lead-in cut — means holes come out round and exactly where you aimed, even on curved metal surfaces. The TiN coating runs at the premium end of the spectrum, reducing friction so the bit stays cooler during extended drilling sequences.

Owners report drilling through thick steel tubing at slow speeds without dulling the bit, and the non-slip shank design prevents the bit from spinning in the chuck under load. The set spans 1/16-inch through 1/2-inch in useful increments, and the plastic case keeps bits organized enough for job-site travel. Cobalt versions of this pilot point exist for dedicated metal workers, but the HSS construction here handles wood, plastic, and mild steel with confidence.

The only real limitation is the round shank — it lacks the hex geometry for impact driver collets, so you are locked into standard drill chucks. For anyone drilling into metal regularly, the pilot point alone justifies the mid-range investment, making this the most consistently sharp set across its price tier.

The HIGHFIRE set is built specifically for impact drivers, with full hex shanks that lock into quick-change collets without spinning or slipping. The 135-degree split point tip provides a no-walk start on steel and aluminum, and the tapered web design adds strength at the transition point where most standard bits snap under high torque. At 22 pieces including sizes up to 1/2-inch, it offers more variety than most hex sets at this price point.

Users report drilling through black slate coasters and wood studs without issue, and the TiN coating keeps the cutting edges sharp through moderate use. The double blister pack is minimal compared to a hard case, but the trade-off is a lower overall weight for tool bag storage. The flutes are optimized to clear chips quickly, reducing heat buildup during continuous drilling.

Because the hex shank is machined as part of the bit rather than added on, concentricity is decent but not as precise as a solid round-shank bit in a three-jaw chuck. For most framing, furniture assembly, and metal drilling tasks it performs admirably, and the slimmer design means you aren’t locked into carrying a separate impact driver and drill.

Ryobi’s AR2042 uses the same hex shank design as the HIGHFIRE set, but the coating here is a standard titanium finish rather than TiN, which offers similar friction reduction at a slightly lower cost. The 135-degree split point tips are consistent across all 22 pieces, and the set includes multiples of the most common small sizes — four 1/16-inch and four 1/8-inch bits — which are the ones most frequently lost or broken.

Compact and light at just 16 ounces, this set fits neatly into a Ryobi tool bag or drawer organizer, and owners praise the hex base for making bits much easier to swap compared to round shanks. It drills cleanly through drywall, softwood, and mild steel, though the coating on bits above 1/4-inch can show wear faster if used on harder materials without lubricant.

The storage case is simple but functional, holding each bit in its own slot with clear size markings. For homeowners who already own Ryobi tools and want a matched set for light-to-moderate drilling, this is a convenient grab-and-go option that won’t overcomplicate the tool kit.

The Lichamp set is built around a 135-degree beveled angle tip with dual chip evacuation grooves, an unusual design that combines a split-point effect with a slightly rounded cutting edge. In practice, this means the bits start faster than a standard 118-degree point on aluminum and plastic, though the trade-off is a slightly shorter sharpness lifespan when drilling into steel. The titanium coating is present on all 21 pieces from 1/16-inch up to 3/8-inch.

Owners report good results for light metal work and general household drilling, with the compact metal storage case being a standout feature at this price point. The round shank design fits most standard chucks securely, and the bits feel substantially built at 1.4 pounds total. Multiple users noted that the bits stay sharp through several projects before needing replacement.

The key limitation is the lack of hex shanks, which means these bits are not ideal for impact driver use at high torque. The 21-piece set also stops at 3/8-inch, so larger holes require stepping up to a separate set. For the price, however, the Lichamp delivers reliable entry-level performance for occasional drilling.

Milwaukee’s Shockwave line is engineered specifically for high-torque impact drivers, featuring a proprietary heat-treatment process that hardens the bit body without making the cutting edge brittle. The 15-piece set covers the most commonly used sizes with a TiN coating that provides reliable friction reduction across hundreds of cycles. The hex shanks are fully ground to match Milwaukee’s quick-change collets without play.

On job sites where bits must survive repeated impacts into steel studs and concrete anchors, the Shockwave design resists snapping at the shank-to-flute transition — the most common failure point in lesser sets. The compact case holds bits securely and fits into the Milwaukee Packout or tool bag without taking up excessive space. The reduced piece count at 15 bits reflects a focus on quality over quantity.

For tradespeople who work daily with impact drivers, the premium construction justifies the higher per-bit cost. Casual home users may find the limited size range restrictive, but for repetitive metal drilling in a professional context, the Shockwave set offers the best durability per bit in this lineup.

This PLATINUMEDGE set is built around quantity — 276 pieces including twist bits, screwdriver bits, and multiple duplicates of each common size, making it suitable for workshops where bits get lost or broken regularly. The twist bits feature a 135-degree fast cutting point that self-centers on contact, and the titanium coating is applied across all HSS bits to reduce heat buildup. The clear lid case lets you see sizes at a glance without opening every drawer.

User reports indicate the bits arrive razor sharp and cut effectively through plastic, aluminum, and mild steel, with the large quantity making it easy to dedicate specific sizes to specific tasks. The S2 steel screwdriver bits are included for fastener driving, adding versatility for furniture assembly and maintenance work. The 20 included twist bit sizes cover 1/16-inch up to 1/2-inch in standard increments.

The main trade-off is that individual bit quality does not match premium single-brand sets — some users noted that bits above 3/8-inch wear faster under heavy use, making this a better choice for mixed-material projects than for dedicated metal fabrication. The case is functional but not job-site rugged, so careful storage is advisable.

The CaRoller set uses a black oxide finish combined with a W4 high-speed steel composition and amber coating, a combination that provides superior wear resistance compared to standard TiN-coated bits when drilling into stainless steel and titanium alloys. The 135-degree split point is fully ground, and the round straight shank design ensures maximum concentricity for clean holes. With 29 sizes from 1/16-inch through 1/2-inch, this is the most comprehensive single-size collection in this lineup.

Owners report drilling 30 holes in a steel I-beam with a single bit at slow speed with proper pressure, producing 8-inch spiral chips in 1/8-inch stainless plate at 300 RPM on a drill press. The black oxide finish retains lubricant well, reducing heat even during extended runs. The expandable plastic case keeps bits organized and is easy to open single-handed on the job.

The trade-off is the round shank, which requires a standard drill chuck and is not intended for impact driver collets. The bits are also noticeably harder than standard HSS, which improves edge retention but makes them slightly more brittle if dropped or twisted aggressively in a hand drill. For serious metal drilling — especially stainless and alloy steels — this set punches well above its price tier.
