What to Look for in Strongest Metal Drill Bits
Important criteria
-
Made from high-speed steel (HSS)
-
Cobalt-infused or solid cobalt for hardness
-
Carbide-tipped for durability
-
Titanium coating for longevity
-
Suitable tip angle for the metal being drilled
-
Appropriate length and diameter for the task
1.) Material Quality
When purchasing the strongest metal drill bit, the primary consideration should be the material it's made from. High-speed steel (HSS) is a common choice for durability and is capable of cutting through most metals. Cobalt steel alloys are superior for their high resistance to heat and wear, making them ideal for drilling into harder metals. Carbide-tipped drill bits are another option, offering exceptional hardness and longevity, but tend to be more brittle and expensive.
2.) Bit Coating
The coating on a drill bit can significantly affect performance. Black oxide is a basic coating that provides heat resistance and lubricity, enhancing the lifespan of a bit. Titanium coatings, such as Titanium Nitride (TiN), offer increased hardness and durability, allowing for faster drilling speeds and less friction. For the toughest jobs, Titanium Aluminum Nitride (TiAlN) or Diamond-like Carbon (DLC) coatings provide exceptional wear resistance and can extend the life of the drill bit even further.

3.) Drill Bit Geometry
The geometry of the drill bit is crucial, as it impacts the bit's cutting efficiency and the quality of the hole. A split point tip (self-centering tip) reduces walking and allows for precise starts. Flute design plays a role in material removal and heat dissipation. Shorter and wider flutes are good for harder materials, while longer, spiral flutes are better for softer materials. Considering the helix angle, point angle, and length of the drill bit will also ensure optimal performance for the task at hand.
4.) Size and Compatibility
Selecting the correct size and type of drill bit for your metal drilling task is essential. Ensure the size matches the requirements of the hole you intend to make. The shank design should also be compatible with your drilling tool. Round shanks are common and can provide adequate grip, but hex or triangular shanks can offer better torque and prevent slippage. Additionally, consider buying sets with multiple sizes or a step bit for versatility in various jobs.

Questions You Might Ask
Metal drill bits are typically made from High-Speed Steel (HSS), Cobalt (HSCO), and Carbide (Carb). HSS bits are suitable for general-purpose drilling in materials like plastic, wood, and mild steel. Cobalt bits are ideal for drilling into harder steel and stainless steel due to their superior hardness and heat resistance. Carbide bits are the hardest and are used for drilling into the toughest materials, but they are also the most brittle and expensive.
Uncoated metal drill bits are good for general drilling applications but can wear off quickly when drilling harder materials. Coated metal drill bits, such as those with Titanium Nitride (TiN), Titanium Carbonitride (TiCN), or Diamond coatings, have increased surface hardness, better heat-resistance, and a lower coefficient of friction. This results in longer bit life and enhanced performance, especially in repetitive drilling applications or when drilling harder materials.
Drill bit geometry refers to the angle and shape of the tip, flute design, and the overall length of the bit. A standard 118-degree point angle is suitable for soft materials, while a 135-degree self-centering split point helps reduce walking and is better for hard materials. The flute design affects chip removal and cooling; parabolic flutes can improve these aspects in deeper holes. Shorter bits are more rigid and accurate, while longer bits can reach deeper with less precision.
Yes, you can use a metal drill bit to drill into wood or plastics; however, it is generally better to use bits designed specifically for those materials. Wood and plastic-specific drill bits have different geometries optimized for cutting those materials efficiently and preventing damage like cracking or splintering.
To ensure the longevity of your metal drill bits, use the correct bit for the material and application, apply the right drilling speed and feed pressure, and use cutting fluid to reduce heat and friction. It's also important to regularly sharpen your bits and to store them properly, avoiding moisture and extreme temperatures that may cause corrosion.

How to Choose the Strongest Metal Drill Bits
Our Pick: Luckyway 20-Piece 1/16"
Embarking on a metal drilling project can be a tough nut to crack. The success of your work hinges on selecting the right tools, with the drill bit being paramount. Drill bits come in various materials, shapes, and sizes, each suited for different tasks and metals. This guide unveils the secrets to choosing the strongest metal drill bits, ensuring precision and efficiency in your projects. Get ready to transform your drilling experience from daunting to doable!
Understanding Drill Bit Materials
When selecting a metal drill bit, the material it's made of matters greatly. High-Speed Steel (HSS) bits are a popular choice for their durability and ability to cut through softer metals like copper and aluminum. Cobalt drill bits, while pricier, excel in dealing with harder metals such as stainless steel, thanks to their superb heat resistance and strength.
Carbide-tipped bits top the charts in terms of hardness and longevity. Ideal for professional settings where precision and endurance are key, these bits can plow through the toughest materials, albeit at a higher cost. It's crucial to weigh your project demands against the bit's material to make an informed choice.
Bit Design and Coatings
Drill bit designs and coatings also play a pivotal role in determining their strength and efficiency. Twist bits, the most common design, are versatile and great for general drilling purposes. However, for more strenuous jobs involving hard metals, consider a step bit or a bullet pilot point.
Coatings such as black oxide, titanium nitride, or diamond powder boost a bit's strength and reduce friction, thus enhancing durability and cutting speed. A coated drill bit can sustain its sharpness longer, making it suitable for intensive metal drilling. Remember, the tougher your project, the tougher your bit's coating should be.
Size and Compatibility
It's essential not to overlook the size of your drill bit. A mismatch between your bit and drill can result in inefficient drilling or even damage to your tool. Make sure to choose bits tailored to your drill's specifications and the job at hand.
Also, consider the shank type—be it a straight shank for standard drills or a hexagonal shank for impact drivers. Ensure compatibility with your drill's chuck for a secure fit. This ensures maximum power transfer, accuracy, and safety during your drilling tasks.
Drill Bit Maintenance and Care
The strength of a metal drill bit is not only inherent but also depends on proper maintenance. Keep bits clean and free from debris to maintain sharpness. Lubrication is also important, especially when working with metals, to prevent overheating and wear.
After each use, inspect your bits for wear or damage. Store them properly in a case or on a magnet strip to avoid blunting their edges. A well-maintained drill bit not only lasts longer but also ensures that every drilling operation is as efficient as the first.
