DEWALT Titanium Nitride Coated Drill Bit Set, Pilot Point, 21-Piece (DW1361)
This 21-piece DEWALT set features titanium nitride coating to extend bit life under metal drilling conditions. The pilot point design reduces walking on contact, helping to start holes cleanly in steel, aluminum, and other metals. The bits use no spin shanks, enabling stable engagement in drills with appropriate chucks. This set targets general metalworking tasks and general construction where reliable, long-lasting bits are desired.
Drill America KFD29J-PC 29-Piece HSS Set
This 29-piece collection from Drill America covers sizes from 1/16″ to 1/2″ in 1/64″ increments, providing a broad spectrum for metal, plastic, and wood work. Made with high-speed steel, these bits offer wear resistance for everyday metal drilling. The black and gold oxide finish enhances corrosion resistance and hardness, helping bits resist heat buildup during longer drilling sessions.
Drill America 29-Piece Cobalt Stepped Point Set (GSC Series)
The GSC29J-PC cobalt set uses gold-stepped point cobalt bits designed to start holes more easily and drill faster with reduced heat. The 135-degree cutting angle and 3-flat shank reduce spinning and promote stability, especially in acrylic, steel, brass, and other hardened materials. A gold oxide finish adds durability and corrosion resistance for tough metalworking environments.
BOSCH CO14B 14-Piece Cobalt M42 Set
The Bosch CO14B set uses cobalt M42 alloys for superior heat resistance and long life, optimized for stainless steel, cast iron, titanium, and other hard metals. The eight-percent cobalt alloy delivers extended life in high-temperature drilling, making these bits suitable for heavier metalworking tasks and repeated use in challenging materials.
DEWALT 21-Piece 135 Degree Split Point Set (DWA1181)
This 21-piece DEWALT set features a 135-degree split point for reduced walking and faster holes, with a parabolic flute design to improve chip ejection in metal and wood drilling. The black oxide coating provides corrosion resistance and durability, helping these bits last longer under metalworking workloads. The included storage system keeps bits organized and accessible in a shop environment.
Buying Guide: Key Purchase Considerations
Material and coating
Look for cobalt (M42) or titanium nitride coatings when drilling hardened metals or stainless steel. Cobalt tools offer higher heat resistance and longer life, while titanium nitride coatings reduce friction and wear. Coatings are most beneficial for persistent metalworking needs or high-temperature tasks.
Tip geometry and point style
A pilot point or split point design minimizes walking on contact, improves hole accuracy, and reduces bit wandering. A 135-degree point helps with penetrating hard metals, while stepped-point designs can improve start-up and reduce heat buildup in multiple-material drilling.
Shank type and compatibility
Flat or three-flat shanks prevent slipping in chuck jaws and provide better torque transfer. Check your drill’s chuck size and whether you need a standard round shank or a flat/three-flat design.
Set range and hole sizes
Choose a set that covers common workpiece thicknesses and hole sizes. For metal work, a range up to 1/2″ is common in home shops, with 1/16″ to 1/4″ being most frequently used for general projects.
Durability in practice
High-speed steel (HSS) is versatile for many metals, but cobalt variants and carbide-tipped options excel with hardened steels and stainless steel. Consider the typical material hardness you encounter when selecting between HSS and cobalt sets.
Storage and organization
Storage cases help protect the bits and keep sizes organized. Look for sets with clear lid visibility or labeled compartments to speed up selection during work.
When selecting a drill bit set for metal work, consider the combination of coating, tip design, shank configuration, and the range of sizes to match your most frequent tasks. The options listed above balance performance, durability, and value, enabling cleaner holes and longer bit life across common metalworking applications.
