10 Best Metal Drill Bits 2025 in the United States

The DEWALT Drill Bit Set is a solid choice for anyone looking to handle a variety of materials, including plastic, wood, and metal. Its 135-degree split point tip design is particularly beneficial as it minimizes walking and allows for accurate drilling. This feature is great for users who may struggle with positioning, especially on harder surfaces.

Made from high-speed steel, these bits are built for durability and can withstand the demands of tough tasks. The tapered web design enhances the bits' strength, helping to resist breakage, which is a common concern with drill bits. Additionally, the black and gold coating not only gives them a sleek look but also serves a practical purpose by protecting against rust and wear over time.

The 3-flats shank design is noteworthy as it reduces spin-out in the chuck, providing a more secure grip during use. This is a valuable feature for anyone who has had issues with bits slipping while drilling. Markings on the shank make it easy to identify sizes quickly, saving time during projects. This set is quite versatile, though those looking for a more extensive range might need to purchase additional bits separately.

The Milwaukee 48-89-9224 Step Bit 6-Piece Set offers a solid option for those needing step drill bits primarily for metals like aluminum, brass, copper, and steel, as well as plastics and wood. Made from alloy steel with a black oxide finish, these bits are designed to resist wear and corrosion, enhancing their durability. The black oxide coating also helps reduce friction and heat buildup during drilling, which is beneficial for clean and efficient cuts.

The set includes six common sizes (#1, 4, 6, 7, 8, 9) that cover a reasonable range of hole diameters, making it versatile for various projects. The straight shank and spiral flute design improve chip removal and overall drilling performance. The taper point style aids in easy bit positioning and prevents slipping, which is especially helpful for users less experienced with metal drilling. At 1.6 pounds total, the bits are easy to handle and control, contributing to better accuracy when working on thin sheet metals or other materials.

This set is a good fit for DIY enthusiasts, hobbyists, or professionals who want a reliable, easy-to-use step bit set for general metal and multi-material drilling without needing specialized, heavy-duty bits.

The Pilot Point design allows for cleaner holes and starts on contact, reducing the chances of wandering, which can be particularly helpful for DIY enthusiasts and professionals alike.

Another advantage is the tapered web design, which provides extra strength and helps minimize breakage during use. This is especially beneficial for users who frequently drill into tougher materials. The no-spin shank is also a thoughtful feature that ensures better grip and easier handling.

There are a few considerations to keep in mind. While the set covers a range of sizes, it may not include all the very small sizes needed for specialized tasks. Additionally, the plastic case, while sturdy, may not be as durable as a metal one, which some users prefer for long-term storage. This drill bit set is well-suited for both home improvement projects and professional needs, offering a blend of quality and versatility that most users will find beneficial.
