10 Best Drill Bits 2026 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 BOSCH CO14B 14-Piece Assorted Drill Bit Set is crafted from Cobalt M42, which makes it highly durable and heat-resistant. This material choice ensures that these drill bits can handle tough materials like stainless steel, cast iron, titanium, and light-gauge metals.

The inclusion of 8% cobalt alloy gives these bits a significantly longer lifespan compared to standard ones. The set features bits in various sizes ranging from 1/16” to 1/2”.

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.
