How to choose
Material Composition
When evaluating the best drill bit quality, consider the material coating. The DEWALT Black and Gold set utilizes high-speed steel with a black oxide coating, while the DEWALT DW1354 set features titanium nitride coating. Makita’s B-65399 Impact Gold set also employs titanium. These coatings are designed to enhance durability and reduce friction during operation. High-speed steel is a standard for general drilling tasks, providing a balance between hardness and flexibility. For specialized applications like metal or cement, ensure the chosen kit explicitly lists compatibility with those materials, as seen in the 246-piece Ultimate Drill Bit Set.
Point Geometry
The geometry of the drill bit tip significantly impacts precision and starting ease. Both the DEWALT DWA1189 and the Norseman 44170 sets feature split-point designs. A split-point tip is engineered to prevent the bit from walking or skating across the workpiece surface upon initial contact. This feature is particularly valuable when drilling into hard or smooth materials where maintaining an accurate center point is essential. In contrast, general-purpose kits may use standard points. If your priority is accuracy and minimizing pre-drilling preparation, look for sets that specify a split-point construction in their product documentation.
Shank Compatibility
Drill bit shanks must match your tool's chuck or impact driver requirements. The Makita B-65399 set is specifically designed with a 1/4-inch hex shank, making it optimized for use with impact drivers. Standard jobber-length bits, such as those found in the Norseman 44170 or DEWALT DWA1189 sets, typically use round shanks designed for standard drill chucks. Before purchasing, verify your tool's chuck type. Using a round shank bit in an impact driver is generally not recommended unless the set is specifically engineered for that interface, which is why matching the shank to your specific power tool is critical.
Kit Versatility
Evaluate whether you require a comprehensive selection or a focused, high-performance set. The Ultimate Drill Bit Set offers 246 pieces, providing an extensive range of bits for wood, metal, cement, and screw driving. This is ideal for workshop environments requiring diverse capabilities. Alternatively, smaller sets like the 14-piece DEWALT DW1354 or the 29-piece Norseman 44170 focus on a core selection of high-quality bits for specific jobber tasks. Choosing between quantity and specialized quality depends on the frequency of your projects and whether you need a single-stop solution or specific, durable bits for repetitive professional-grade drilling.
Core Strength
Core strength is a key indicator of drill bit quality, particularly for preventing breakage under torque. The DEWALT DWA1189 set highlights an optimized helix and a stronger core as primary features. A reinforced core is designed to withstand the stresses of high-speed drilling, which can be critical when working with dense materials. While smaller sets prioritize portability and material coatings, checking for mentions of core design or reinforced construction can help identify bits built for longevity. Always review the product name and description for mentions of structural enhancements that contribute to the overall durability of the drill bit set.
Frequently asked questions
What is the benefit of a titanium nitride coating?
Titanium nitride coating, featured on products like the DEWALT DW1354 and Makita B-65399, is applied to drill bits to improve their surface hardness and heat resistance. This coating helps the bit maintain its sharpness for a longer duration compared to untreated high-speed steel. It is particularly useful for drilling into harder materials where friction can quickly degrade a bit's cutting edge. By reducing friction, the coating helps the bit glide more efficiently through the workpiece.
Are hex shank bits better for impact drivers?
Yes, hex shank bits, such as those found in the Makita B-65399 set, are designed specifically for the quick-release chucks found on impact drivers. They provide a secure fit that prevents the bit from slipping during high-torque applications. Standard round shank bits are intended for use with traditional drill chucks. Using the correct shank type ensures stability and prevents damage to both your drill bit and the tool's chuck mechanism during operation.
Why should I choose a split-point drill bit?
Split-point drill bits, available in the DEWALT DWA1189 and Norseman 44170 sets, are engineered to start drilling immediately upon contact. The specialized tip geometry prevents the bit from 'walking' or sliding off the intended mark on the workpiece. This is a significant advantage when drilling metal or other hard surfaces where a precise starting point is necessary. This feature minimizes the need for center punching or pilot holes, saving time and increasing overall project accuracy.
What is the difference between a jobber set and a comprehensive kit?
A jobber set, like the Norseman 44170, typically contains a specific, limited selection of bits sized for general-purpose drilling tasks. These sets prioritize higher-grade materials and professional-level construction. In contrast, comprehensive kits like the 246-piece Ultimate Drill Bit Set include a vast variety of bits, often covering wood, metal, and masonry, along with screw-driving accessories. These are intended to be all-in-one solutions for users who need a wide array of options in one organized carrying case.
How do I know if a drill bit is suitable for cement?
To determine if a bit is suitable for cement or masonry, check the product description for explicit compatibility. For instance, the Ultimate Drill Bit Set is specifically marketed for wood, metal, and cement drilling. Masonry-specific bits are designed with different cutting edges compared to standard metal or wood bits. If a set does not explicitly mention cement or masonry compatibility, it is best to assume it is intended for metal and wood applications only.
Bottom line
For users seeking the highest standard of drill bit quality, the Norseman 44170 Ultra Dex Type 240-UB set stands out for its 135-degree split point and Magnum super premium construction, which aligns with professional-grade expectations. When comparing professional reliability, the DEWALT DWA1189 set also excels with its optimized helix and stronger core design, making it a top contender for heavy-duty applications. While the Ultimate Drill Bit Set provides unmatched versatility with 246 pieces, the Norseman and DEWALT DWA1189 sets are better suited for those prioritizing high-performance materials and specialized geometry. For impact driver users, the Makita B-65399 titanium-coated set offers the most precise fit for that specific tool platform.
Deciding on the right set requires balancing your specific tool type and the materials you encounter most frequently. If you primarily use an impact driver, prioritize the Makita B-65399 for its compatible hex shank. If you work primarily with metal and require precision, select the Norseman 44170 or DEWALT DWA1189 for their split-point accuracy. For homeowners or DIY enthusiasts who need one solution for various materials including cement, the comprehensive Ultimate Drill Bit Set is the most practical choice. Always check your tool's chuck requirements and the specific material ratings provided in the product name before finalizing your purchase to ensure maximum compatibility and long-term utility.
