DEWALT 14-Piece 135° Split Point Set
DEWALT’s 14-piece set uses a 135-degree split point to minimize walking on start, making it suitable for plastic, wood, and metal. The high-speed steel construction delivers durability for everyday tasks, while a tapered web design helps resist breakage in demanding applications. The 3-flats shank ensures a secure grip in standard and quick-change chucks, reducing cam-out during aggressive drilling. This kit covers common hole sizes and applications, making it a versatile option for garage projects and light fabrication.
DEWALT Titanium Nitride Coated, Pilot Point, 21-Piece
This 21-piece DEWALT set features a Titanium Nitride coating for extended bit life and a pilot point that begins on contact for cleaner holes. The no-spin shanks reduce bit slippage, particularly helpful in metal and hard plastic. The assortment supports a range of hole sizes, enabling more precise work without frequent tool changes. Ideal for users who expect longer tool life in mixed-material projects.
COMOWARE Titanium Twist Drill Bit Set (16 Pcs)
The COMOWARE set uses a titanium coating on classic HSS for durability and sharpness. Designed for a smooth, chatter-free experience with staggered teeth, these bits deliver clean countersinks and precise holes. The 1/4 inch hex shank supports quick-change chucks, making it convenient for rapid bit swaps in wood, plastic, and light metal work. The kit emphasizes chip clearance and cooler operation, aiding longer bit life in daily tasks.
Makita B-65399 Impact Gold 14-Piece
Makita’s Impact Gold set features TiN coating that lasts about 2.5 times longer than non-coated bits, providing extended life under heavy use. The 135-degree split point geometry reduces walking at the start, while the 1/4″ hex shank is built for impact drivers. This makes the set well-suited for tough metal and hardwood tasks where driver torque is high and bit life matters. A reliable choice for a contractor or avid DIYer using impact tools.
DEWALT 21-Piece Black Oxide Set
This DEWALT 21-piece kit uses a black oxide coating to resist corrosion and improve durability in metal and wood drilling. The parabolic flute design improves chip ejection, increasing efficiency in metal and wood drilling. The 135-degree split point helps start holes accurately with reduced wandering. It covers a broad range of sizes for general-purpose drilling and light fabrication tasks, providing dependable performance across common materials.
Buying Guide
Key purchase considerations help match drill bits to intended tasks and tools. Consider material compatibility, coating, point geometry, and shank design when selecting a set.
- Material and coating: Titanium Nitride (TiN) or black oxide coatings extend life and reduce wear. TiN is especially beneficial for metal and hard plastics, while black oxide offers corrosion resistance for general use.
- Point geometry: A 135-degree split point reduces walking on contact, improving accuracy in soft and hard materials. Pilot points aid start accuracy in metal and wood, and parabolic flutes improve chip ejection for metal and wood drilling.
- Shank type: Hex shanks enable quick-change chucks and more secure mating with impact drivers, while 3-flats shanks help prevent slipping in standard chucks.
- Materials and applications: High-speed steel (HSS) is versatile for wood, plastic, and softer metals. For masonry, carbide-tipped bits are preferred. For heavy metal work with impact drivers, impact-rated bits deliver durability under higher torque.
- Kit composition: Consider the range of sizes included and whether the set suits your primary tasks (metal fabrication, woodworking, masonry, or mixed use). A balanced set minimizes constant tool swapping.
- Drive compatibility: If you use an impact driver, prioritize impact-rated bits with hex shanks or quick-change compatibility. For drill presses, ensure the shank size fits the chuck you own.
Overall, the best drill bit set depends on your typical projects: wood-focused tasks benefit from tough, sharp HSS or TiN-coated bits; metal and hard plastics gain from titanium or carbide-tipped designs; and masonry work requires carbide cores with robust shanks. For homeowners, a versatile 14–21 piece kit often provides enough sizes to cover most tasks, while professionals may prefer sets that maximize durability and lifespan in demanding environments.
