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 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 DEWALT Drill Bit Set (DWA1184) is a versatile 14-piece collection, perfect for those who often work with plastic, wood, and metal. One of its standout features is the 135-degree split point tip design, which helps to prevent the bit from walking when you start drilling, making it user-friendly, especially for beginners. The high-speed steel construction ensures durability and performance, while the black and gold coating adds a layer of protection against rust and wear, extending the tool's lifespan.

The tapered web design enhances strength, reducing the likelihood of breakage during use. Additionally, the 3-flats shank helps to minimize spin-out in the chuck, ensuring a more secure drilling experience. Another practical aspect is the size markings on the drill bit shank, making it easy for users to quickly identify the right bit for the job.

This DEWALT drill bit set is an excellent choice for DIY enthusiasts and home improvement projects, offering a reliable and durable solution for common drilling needs. However, those requiring specialized or heavy-duty bits may need to look elsewhere.
