How to choose
Material Composition
The material of a drill bit dictates its durability and intended surface. Cobalt bits, such as the Bosch CO14B M42 set, are engineered for demanding tasks like drilling through stainless steel, titanium, and cast iron. High-speed steel options, like the Drill America KFD29J-PC and Norseman 44170, offer reliable performance for general heavy-duty metal applications. When selecting a set, verify the material hardness against your project requirements to ensure the bits can withstand the heat and friction generated during operation. Choosing the correct metallurgical composition is the primary factor in preventing premature bit dulling or catastrophic breakage during professional or home workshop use.
Bit Count and Variety
Inventory size varies significantly between comprehensive kits and specialized sets. The Ultimate Drill Bit Set provides 246 pieces, offering a wide variety for wood, metal, and cement, making it suitable for users needing an all-in-one solution for diverse tasks. In contrast, focused sets like the Norseman 29-piece or Bosch 14-piece kits prioritize precision and depth within a specific category. A large kit is often best for those starting a workshop, while smaller, high-quality sets are ideal for tradespeople who already possess a base collection and require specialized, high-performance replacements for consistent, repetitive drilling tasks.
Shank Design and Compatibility
The shank configuration determines how the bit secures into your power tool chuck. The Bosch CO14B set features a three-flat shank design, which helps prevent the bit from slipping under high-torque conditions common in metal drilling. Standard round shanks, found on the Drill America KFD29J-PC and Norseman 44170 sets, are the industry standard for most jobber-length applications. Ensure your drill chuck is compatible with the shank type of your chosen set. For screwdriving tasks, the DeWalt DW2166 set provides bits specifically engineered for compatibility with standard driver bit holders, ensuring secure engagement for fastening applications.
Point Geometry
The tip design, or point geometry, significantly influences how quickly a bit begins cutting. The Norseman 44170 set utilizes a 135-degree split point, which is designed to reduce walking on the material surface and allow for faster, more accurate starting without a center punch. Standard points are common in many general-purpose sets, but split points are preferred for harder materials where precision is critical. When shopping, check the product specifications for point angles, as a 135-degree split point is generally more efficient for self-centering in metal compared to standard points found in larger, multi-purpose kits.
Storage and Organization
An organized storage solution is essential for protecting the integrity of your drill bits and ensuring efficient workflow. The DeWalt DW2166 comes with a Tough Case, while the Drill America set utilizes a round case for its 29-piece collection. Bosch provides a dedicated case for its 14-piece cobalt set, ensuring bits remain categorized and accessible. For massive kits like the 246-piece Ultimate Drill Bit Set, organized carrying cases are vital to keep components from becoming disorganized. Proper storage prevents bits from knocking against each other, which preserves the sharpness of the cutting edges and prevents loss of individual pieces.
Frequently asked questions
Which drill bit set is best for drilling through stainless steel?
For drilling into difficult materials like stainless steel, cast iron, and titanium, the Bosch CO14B 14-Piece Cobalt Drill Bit Set is a strong candidate. These bits are manufactured from M42 cobalt, a material specifically chosen for its ability to withstand the high heat and pressure associated with drilling hard metals. The inclusion of a three-flat shank also provides improved grip, which is essential when working with stainless steel to prevent the bit from slipping in the chuck.
Can I use a general-purpose bit set for all home repairs?
A comprehensive kit like the 246-piece Ultimate Drill Bit Set is designed for versatility, covering wood, metal, and cement drilling, as well as screw driving. While this kit offers the widest range of applications, specialized sets like those from Norseman or Bosch offer higher performance for specific metal-working tasks. If your projects involve a mix of basic home repairs, a large, all-in-one kit provides the necessary variety, whereas professional metal fabrication typically requires specialized, higher-grade steel or cobalt bits.
What is the advantage of a 135-degree split point?
The 135-degree split point, featured in the Norseman 44170 set, is engineered to provide a self-centering action. This design minimizes 'walking' or wandering on the surface of the workpiece when you first engage the drill. By allowing the bit to bite into the material immediately upon contact, it increases accuracy and reduces the physical effort required to start a hole. This feature is particularly beneficial when drilling into hard or slick surfaces where standard bits might skid.
Does the DeWalt DW2166 set include drill bits for metal?
No, the DeWalt DW2166 is a 45-piece screwdriver bit set designed specifically for fastening and screwdriving tasks. It is not intended for drilling holes into wood, metal, or cement. If your project requires drilling, you should look at the other sets listed, such as the Drill America KFD29J-PC or the Bosch CO14B, which are specifically engineered for cutting applications. The DeWalt set is best used as a complementary tool for driving screws once the pilot holes have been drilled.
Are all drill bit sets compatible with standard handheld drills?
Most jobber-length sets, such as the Norseman 44170 and Drill America KFD29J-PC, feature round shanks compatible with standard drill chucks. The Bosch CO14B set uses a three-flat shank, which also fits standard chucks while offering improved torque transmission. However, always check the maximum chuck size of your drill—typically 3/8-inch or 1/2-inch—to ensure the shank diameter of the bits in your chosen set will fit securely. Always verify the maximum capacity of your specific drill before purchasing.
Bottom line
When selecting the best quality drill bit set, the Norseman 44170 Ultra Dex Type 240-UB stands out as a superior choice for precision metal applications due to its 135-degree split point and high-performance design. For those requiring specialized power for the toughest materials like stainless steel or titanium, the Bosch CO14B Cobalt set is the most reliable option, offering the M42 material hardness needed to handle extreme heat without failing. The Drill America KFD29J-PC serves as a robust, high-speed steel standard for general heavy-duty tasks. Meanwhile, the Ultimate Drill Bit Set provides unmatched value for users who prioritize total variety over specialized metal-drilling performance, and the DeWalt DW2166 remains the essential companion for all screwdriving and fastening needs.
Deciding on the right set depends primarily on your specific application and the hardness of the materials you intend to drill. If your work involves frequent metal fabrication, prioritize the cobalt and M42 steel options like the Bosch or Norseman sets for their superior heat resistance and point geometry. If you are a homeowner needing a single, comprehensive solution for occasional wood, cement, and metal drilling, the 246-piece Ultimate Drill Bit Set offers the necessary inventory to handle diverse tasks.
