10 Best Drill Bit Sets 2025 in the United States

The DEWALT Drill Bit Set (DWA1181) is a versatile 21-piece set suitable for general-purpose drilling in various materials, including metal, wood, plastic, PVC, and fiberglass. The bits are black oxide coated, which helps to resist corrosion and extend the lifespan of the bits, making them durable. The 135-degree split point design allows for easy drilling on contact, which helps prevent the bits from slipping on hard surfaces.

Additionally, the 31-degree helix angle reduces the aggressiveness, making it suitable for deeper drilling applications without compromising control and precision. These features make it a reliable choice for both DIY enthusiasts and professional users who need a solid set of drill bits for a range of tasks. On the downside, while the set covers a broad range of sizes, it might not include some specialized bits needed for very specific applications.

Being made in China might also concern some users who prefer locally manufactured tools. However, these drawbacks are minor compared to the performance and reliability that the DEWALT brand ensures. In summary, this drill bit set is ideal for those who need a robust, all-purpose set that is easy to use and offers good longevity.

The DEWALT Drill Bit Set (DWA1184) is a 14-piece collection that offers significant versatility for tackling various materials including plastic, wood, and metal. One of its standout features is the 135-degree split point design, which helps prevent the bits from wandering off during drilling, making it user-friendly, especially for those who might not have the steadiest hands. The high-speed steel construction is a strong point as it ensures the bits are durable and can withstand heavy use, which is crucial for both DIY enthusiasts and professionals. The black and gold coating not only gives the bits a sleek appearance but also protects them from rust and wear, extending their lifespan. Additionally, the tapered web design reduces the chances of breakage, enhancing the set's reliability.

While the set is well-suited for a variety of materials, it may not be the best choice for very specialized applications, such as masonry or applications requiring particularly hard or abrasive materials. Some users have noted that the bits could be better suited for larger drilling tasks, as their size range might limit their effectiveness in more precise or delicate work. Despite the size markings on the shank for quick identification, a beginner might still find it a bit confusing when selecting the right size without some guidance.

This DEWALT drill bit set is ideal for those looking for a reliable and versatile option for general drilling tasks, making it a great choice for homeowners and casual DIYers. However, professionals or those requiring more specialized drill bits may want to consider additional options tailored to specific needs.

The BOSCH CO14B 14-Piece Assorted Set is a solid choice for anyone looking to tackle a range of drilling projects, particularly in tougher materials like stainless steel, cast iron, and titanium. One of the standout features is the M42 cobalt construction, which offers enhanced durability and heat resistance, making these bits last significantly longer than standard options. The inclusion of a three-flat shank design helps to prevent slipping, which is especially useful when drilling into hard surfaces. With sizes ranging from 1/16" to 1/2", this set caters to various drilling needs, allowing for versatility in both home and professional environments.

The cobalt material and titanium finish provide excellent performance, but they may not be necessary for casual DIY users who primarily work with softer materials like wood or plastic. For these users, investing in a more basic set might be more cost-effective. Additionally, some users may find the bits to be more expensive compared to other standard drill sets, which could be a consideration for budget-conscious buyers.

The BOSCH CO14B set excels in demanding applications and is ideal for professionals or serious hobbyists who need reliable drill bits for challenging tasks. Those with only light drilling needs may not fully utilize the advantages these bits offer.
