10 Best Drill Bits 2025 in the United States

The IRWIN Tools Hanson Screw Extractor and Drill Bit Set is a handy tool kit designed primarily for removing broken studs, bolts, socket screws, and fittings. It includes 35 pieces, making it suitable for a variety of extraction tasks, which is great for DIY enthusiasts and professionals alike. One of its standout features is the aggressive left-hand design that enhances gripping power, especially useful when the resistance increases. The easy-out spiral flutes are designed to embed themselves, further improving grip during tough extraction scenarios.

In terms of construction, the bits are made from cobalt alloy steel, known for its durability and ability to withstand high temperatures, which is a strong point for those who need reliable tools. The sizes of extractors and recommended drill bits are etched on each tool, which adds convenience and helps users choose the right bit quickly.

There are a few drawbacks to consider. The kit may be more suited for specific tasks like removing broken hardware rather than general drilling, limiting its use for those who need an all-around set. The relatively small cutting diameter of 0.09 inches may not suffice for larger jobs, and while the lifetime warranty is a plus, it does not cover abuse, which means careful handling is required. Additionally, the product's weight at 3.42 pounds could be considered cumbersome for some users.

The Milwaukee 29 Pc. Cobalt Red Helix Metal Drill Bit Set is designed for metal drilling tasks, making it a good choice if you often work with tough metals. Its cobalt material is a major strength because cobalt bits are known for being durable and heat-resistant, which helps the bits last longer when drilling hard metals. The 135-degree cutting angle is ideal for metal, as it provides a balanced sharpness that reduces walking and improves precision.

These bits have a straight shank, which fits well in most standard drill chucks, making them easy to use with many drills. The black oxide finish offers some protection against rust and helps reduce friction, though it’s not as durable as other coatings like titanium. The set includes 29 pieces, so you get a wide range of sizes, which is handy if you need versatility for different hole sizes.

The package is a bit on the heavier side (almost 3 pounds), so it’s more suited for workshops or job sites rather than occasional light use. This set is a solid choice for users who regularly drill metal and want reliable, long-lasting bits with good size variety. However, if you mostly drill softer materials or want the absolute lightest set, you might look elsewhere.

The Milwaukee 48-89-9224 Step Bit 6-Piece Set is a well-constructed option for both DIY enthusiasts and professionals who need versatile drilling solutions. The set includes six different sizes, which makes it suitable for various applications, from simple home projects to more complex tasks. One of its clear strengths is the use of alloy steel, providing durability that can withstand frequent use without significant wear. Additionally, the black oxide finish helps reduce friction and improves the longevity of the bits.

The straight shank design enhances compatibility with standard drill chucks, making it convenient to use across different drills. Users will appreciate how easy these bits are to handle, making drilling through various materials straightforward. This ease of use, combined with the range of sizes, means it's a good choice for those who might not have extensive experience with power tools.

There are a couple of considerations. While the bits are durable, they may not be the best fit for extremely hard materials or heavy industrial use, as they are primarily designed for lighter applications. Additionally, some users might prefer a set with more sizes or additional features, such as quick-change shanks, which this set does not include.
