High-Speed Steel Drill Bits for Stainless Steel and Metal
Incorporating the STROTON Cobalt Drill Bit Set into my daily toolkit has been quite a game-changer. With its split point design tip, I’ve found that it starts drilling immediately with less force, eliminating the “walking” motion across the work surface that I often encounter with other drill bits.

Buyer’s Guide
When it comes to drilling through steel, having the right drill bit can make all the difference. In this buyer’s guide, we’ll go over the important features and considerations when purchasing steel drill bits, as well as some general advice to ensure you get the best product for your needs.
Material: What Steel Drill Bits Are Made Of
One of the most important factors when choosing steel drill bits is the material used to make them. Common materials include high-speed steel (HSS), carbide, and cobalt. HSS is often the most budget-friendly option, while carbide and cobalt tend to be more durable and capable of handling tougher materials.
Shank Size: Understand Your Drill Bit Shank Size
The shank size of a drill bit refers to the diameter of the part that fits into the drill chuck. Standard shank sizes include 3/8", 1/2", and 3/4". Ensure that the shank size you choose matches the drill you are using for optimal performance and safety. Smaller shanks tend to be lighter and easier to maneuver, while larger shanks provide more stability and are suitable for heavier drilling tasks.
Flute Width: Choose the Right Flute Width for Your Project
The flute width refers to the space between the cutting edges of a drill bit. The flute width affects the bit’s drilling capacity, drilling speed, and chipping resistance. Wider flutes allow for faster drilling but can create more debris and require more frequent cleaning. Narrower flutes may drill more slowly but are capable of producing cleaner holes and are useful for precision drilling.
Tip Size and Shape: Consider the Bit’s Tip Size and Shape
The tip size and shape of a steel drill bit play a crucial role in its ability to penetrate the material. Bits with a larger tip size require less initial force to start drilling, but they may be less efficient in cutting through the material. Bits with a smaller tip size need more initial force but can cut more efficiently once drilling has begun. In terms of shape, cylindrical tips are generally suitable for most materials, while helix tips are designed for drilling curved paths, such as in hole reaming.
