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 SONCHIE Serrated Masonry Drill Bit Set is designed for both household and professional use, especially for drilling into tough materials like concrete, tile, glass, and brick. Made from durable carbide, these bits promise a longer lifespan compared to standard bits. Their unique serrated edge and spiral flutes help clear debris efficiently, making drilling smoother and faster.

The set includes 5 bits ranging from 1/4 to 9/16 inch, which covers many common drilling sizes but may be limiting if you need larger or very small bit sizes. These bits come in a sturdy plastic case for easy storage and transport, useful for DIYers or contractors working on site. The set focuses on masonry and hard surfaces, but it can also handle softer materials like wood and plastic, adding versatility.

It doesn’t feature a special coating like titanium or diamond, which some might expect for extra durability. For those seeking a reliable, well-built set for general masonry and home projects, this drill bit set offers good value. However, if a wider size selection or specialized coatings for heavy-duty industrial use are needed, exploring additional options may be beneficial.
