How to choose
Material Composition
When selecting drill bits, the material dictates durability and heat resistance. High-Speed Steel (HSS) is a common standard, often enhanced with titanium coatings to improve longevity and reduce friction during operation. The Norseman 44170 set and Milwaukee 48-89-4670 bits utilize specialized metallurgy for demanding tasks. Evaluate whether your projects require basic HSS for occasional household use or premium, hardened alloys designed for professional-grade impact drivers and high-stress drilling applications. Always prioritize bit sets that explicitly state their coating or steel grade to ensure the tool matches the hardness of the materials you intend to drill through, whether wood, metal, or plastic.
Set Size and Variety
The scope of your project determines the ideal set size. Large kits like the Hi-Spec 130pc set or the SKIL 120pc drilling and driving set offer comprehensive ranges, including various diameters to handle diverse fasteners and hole sizes. These are beneficial for workshops requiring immediate access to many sizes. Conversely, smaller, task-specific sets like the 8-pack serrated side-cutting bits provide specialized geometry for unique cuts. Assess your storage capacity and the frequency with which you switch between bit sizes to decide if a massive, all-in-one organizer or a streamlined, job-specific set better serves your workflow and organizational needs.
Point Geometry and Design
Drill bit geometry, such as the 135-degree split point found on the Norseman 44170 set, is engineered to prevent bit walking on the material surface, allowing for more precise hole placement. Other designs, like the serrated side-cutting bits in the 8-pack, allow for lateral movement to create slots or unique shapes. When browsing, look for the specific cutting angle or edge design listed. A split point is generally superior for self-starting in metal, while specialized designs offer versatility for woodworking or plastic applications. Match these geometric features to the specific precision required for your drilling tasks to achieve cleaner holes.
Impact Compatibility
Not all drill bits are designed to withstand the high-torque output of modern impact drivers. The Milwaukee 48-89-4670 set is specifically labeled as Impact Duty, indicating it is engineered to handle the intense stress these tools exert. Using standard HSS bits in an impact driver can lead to premature snapping or failure. If your primary tool is an impact driver, prioritize sets explicitly marketed for impact resistance. For standard drill-drivers, a wider range of HSS or titanium-coated bits will suffice, but ensure the shank design, such as a hex shank, is compatible with your specific chuck or quick-change system.
Storage and Organization
Effective organization is essential for maintaining bit sets over time. Products like the Hi-Spec set feature labeled storage to help quickly identify the correct diameter, while the SKIL 120pc set provides a comprehensive layout for both drilling and driving accessories. A portable, workshop-ready case minimizes the risk of losing small bits and keeps them protected from moisture and debris. Consider the physical footprint of the case and whether the internal layout allows for easy retrieval. A well-organized case not only protects your investment but also improves efficiency by ensuring the right bit is always accessible during your project.
Frequently asked questions
What is the benefit of a 135-degree split point bit?
A 135-degree split point, found in the Norseman 44170 set, is designed to reduce the tendency of the bit to wander or 'walk' across the surface of the material when starting a hole. This geometry allows the bit to bite into the metal immediately upon contact, providing greater precision and stability. It is particularly useful when drilling into harder materials where a standard, shallower point might slip before penetrating the surface.
Can I use any drill bit in an impact driver?
No, you should prioritize bits explicitly designated for impact use, such as the Milwaukee 48-89-4670 Shockwave Impact Duty bits. Impact drivers generate high-torque, percussive force that can shatter standard drill bits not engineered to absorb that specific stress. Always check the product description for 'Impact Duty' or similar ratings to ensure the bit is rated for the mechanical shock produced by an impact driver, preventing premature failure or potential injury during operation.
Why choose titanium-coated bits over standard HSS?
Titanium-coated HSS bits, such as those included in the Hi-Spec or 8-pack serrated kits, generally offer improved heat resistance and reduced friction compared to uncoated HSS bits. This coating helps the bit maintain its edge sharpness longer when drilling through difficult materials like metal or plastic. While standard HSS is suitable for many lighter tasks, titanium coating is a common feature for users seeking extended bit life and cleaner drilling performance in a workshop environment.
Are serrated side-cutting bits necessary for woodworking?
Serrated side-cutting bits, like those in the 8-pack titanium-coated set, provide unique functionality beyond standard drilling. The side-cutting edges allow you to move the drill bit laterally to create slots, notches, or irregular holes in wood, plastic, and metal. They are not strictly necessary for simple hole-drilling tasks but serve as a versatile woodworking tool for users who need to shape or enlarge openings without switching to a different tool like a jigsaw or router.
What should I look for in a large, all-in-one drill bit set?
For large sets like the Hi-Spec 130pc or SKIL 120pc options, look for clearly labeled storage cases that keep bits organized by size. A well-organized set reduces time spent searching for the correct bit. Additionally, ensure the set includes a broad range of diameters to cover common household and workshop fasteners. If you perform diverse projects, these comprehensive kits are efficient, as they keep your drilling and driving accessories in one portable, easy-to-manage location.
Bottom line
For users prioritizing professional-grade performance and durability, the Norseman 44170 Ultra Dex set is a top contender, boasting a high 4.7 rating and a 135-degree split point design that excels in metal applications. However, if your work involves modern impact tools, the Milwaukee 48-89-4670 Shockwave set is the strongest fit, as its 4.8 rating reflects its specialized engineering for high-torque environments. For general workshop versatility, the SKIL 120pc set provides an expansive range of drilling and driving bits, making it a robust choice for those needing a comprehensive, all-in-one solution. Each of these sets offers specific advantages—whether it is the precision of Norseman, the durability of Milwaukee, or the sheer variety offered by SKIL.
Deciding between these sets depends on your primary tool and material requirements. If you frequently use an impact driver, narrow your search exclusively to sets labeled 'Impact Duty' to ensure safety and longevity. For those performing general home repairs or woodworking, a large, organized kit like the SKIL or Hi-Spec options will provide the necessary variety of sizes for most fasteners. If your projects involve drilling through dense metal, prioritize the Norseman set for its specialized point geometry. Always match the bit material and design to your specific tool type and project demands to ensure the best results and the longest product life.
