Makita Titanium Hex Shank Bits
Makita’s B-65399 set uses a titanium nitride coating that extends life up to 2.5 times longer than non-coated bits. The 135-degree split point starts quickly and reduces walking, which is especially helpful when working with metal surfaces. Designed for 1/4-inch hex impact drivers, these bits are built for tough drilling tasks where power tools push aside resistance.
The 14-piece pack covers a broad range of common metal drilling needs, from small pilot holes to larger countersinks. The TiN coating reduces wear, while the split-point geometry aids precision on hard metals. This set is a solid option for DIY metalwork, fabrication, and automotive tasks that require durable, reliable bits in a compact kit.
SKIL Hex Shank Twist Drill Bits
SKIL’s 15-piece TDB5000 set features a 135-degree split angle to ensure fast starts with minimal wandering. The 1/4-inch hex shank fits both drills and impact drivers, making it a practical choice for quick, repeated drilling in metal and light-duty steel work. The black and golden oxide coating helps extend bit life by reducing heat buildup and wear during high-speed drilling.
In metalwork, the hex shank design reduces slippage in quick-change chucks, especially when you’re applying pressure. The set covers a variety of common hole sizes, balancing affordability with performance for hobbyists and pros alike who need dependable bits for metal fabrication, automotive work, and home repairs.
HIGHFIRE Hex Shank Drill Bit Set
The HIGHFIRE set offers 22 pieces with a 135-degree split point, designed to start cleanly and reduce slip when drilling into metal. Its hex shank is compatible with quick-change chucks and impact drivers, helping to prevent bit spinning under load. The variety of sizes supports multiple projects, from light gauge sheet metal to thicker metal stock, with an emphasis on long-lasting performance and efficient chip removal.
These bits emphasize stable cutting geometry and a robust coating to cope with the friction involved in metal drilling. The double blister pack packaging also helps with organization, making it easier to select the right bit for the job and to keep the bits protected when not in use.
COMOWARE Titanium 30-Pcs Hex Shank Set
COMOWARE’s 30-piece hex shank set utilizes a titanium coating on HSS to improve durability and heat resistance. The 1/4-inch hex shank is designed for quick-change chucks, enabling fast bit swaps on the job. The set is well-suited for extensive metal drilling tasks, including drilling through steel and other alloys, with an emphasis on reducing chatter and delivering cleaner holes.
The included bits span a broad range of hole sizes, offering a balanced option for both light and heavier metalworking. The improved edge geometry helps maintain precision while minimizing bit deflection under pressure, a common factor when drilling into metal with adjustable tool speed.
Sinyeenglon Cobalt Hex Shank Bits
Cobalt M35 material drives top-tier hardness and heat resistance, delivering a dramatic performance boost in hard metals. The hex shank design reduces the risk of bit looseness in the chuck, and the set’s optimized torque characteristics help ensure straight, true drilling with less radial runout. These bits are engineered for demanding tasks where metal hardness and frequent use demand reliable performance.
The 13-piece collection emphasizes high-torque capability and longevity, making it a practical choice for automotive, construction, and fabrication settings. The cobalt composition provides extended life when drilling hardened steel and alloys, with a focus on consistent hole quality and minimal bit wandering.

The titanium coating reduces heat buildup and wear during extended drilling sessions.
Buying Guide: Key Purchase Considerations
- Coating and hardness: Titanium nitride, titanium, and cobalt coatings extend life and heat resistance when drilling metal. For hard alloys, cobalt blends like M35 improve performance at higher temperatures.
- Shank compatibility: A 1/4″ hex shank supports quick-change chucks and impact drivers, reducing bit slip and enabling faster tool changes on metal projects.
- Point geometry: A 135-degree split point starts holes accurately and minimizes walking, which is essential on smooth metal surfaces. This feature is particularly helpful for beginners and inDIY contexts.
- Bit variety: Sets with a broad size range cover common metalworking tasks from pilot holes to larger through-holes. Consider future needs when choosing a set.
- Durability vs. budget: Higher-quality coatings and cobalt bits generally cost more but resist wear longer under demanding use. For frequent metal drilling, investing in a premium set improves long-term value.
- Tool compatibility: Ensure the bits fit your power tools’ chucks and drivers. Quick-change chucks benefit most from hex shank designs to prevent slippage and improve efficiency.
- Organization: Sets with clear holders or index systems save time on projects that require switching between multiple sizes.
When selecting hex shank drill bits for metal, balance the project scope, tool compatibility, and expected usage life. The options above provide a range of coatings, sizes, and price points to suit hobbyists through professional shop environments, with a common emphasis on durability, reduced walking, and rapid bit changes.
