10 Best Drill Bit Sets 2025 in the United States

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.

The Makita B-65399 Impact Gold 14 Pc. Titanium Drill Bit Set is a versatile choice for those who need to drill through various materials such as ferrous metal, wood, plastic, non-ferrous metal, cast iron, and stainless steel. These drill bits are made from stainless steel and come with a titanium nitride (TiN) coating, which significantly enhances the durability by allowing them to last 2.5 times longer than non-coated bits. This makes them a robust option for frequent use in tough materials.

The set includes 14 pieces with a size range from 1/16 to 1/2 inches, catering to a wide range of drilling needs. The 135-degree split point geometry helps in faster starts and reduces bit walking, ensuring precise drilling. Moreover, the hex shank design is specifically rated for use in 1/4 inch hex impact drivers, providing secure bit retention and reducing the risk of slippage during use.

However, it is important to note that the manufacturer does not provide a warranty for this product, which might be a concern for some users. Also, while the titanium nitride coating adds durability, it may still wear off over time with extensive use in hard materials. Despite these minor drawbacks, the set remains a reliable option for both DIY enthusiasts and professionals.

The Milwaukee 48-89-4680 18-Piece Shockwave Impact Duty Thunderbolt Titanium Drill Bit Set is designed for those who frequently engage in heavy-duty drilling tasks. One of its standout features is the titanium coating, which helps reduce heat and minimizes warping during rapid use, making it safer for extended applications. The unique Shockwave geometry is engineered to withstand high torque applications, ensuring durability and longevity for demanding jobs. Additionally, the parabolic flute design aids in chip clearing, which can enhance drilling speed and efficiency by reducing friction and heat buildup.

This set includes a wide variety of bit sizes, making it versatile enough for many different projects, from small to larger-scale tasks. The robust plastic storage case is also a significant plus, featuring a slide lock system that keeps bits secure and organized, whether you're transporting them or storing them in your tool kit.

While the titanium coating is beneficial, it may not be as effective against wear as some premium materials over extensive use. Users looking for specific specialty bits might find that this set, while comprehensive, doesn't cover every possible need. Moreover, for those new to drilling, the variety of sizes may be overwhelming if you’re unsure which bits to choose for certain tasks.
