Cobalt steel, high-speed steel (HSS), and carbide-tipped drill bits are among the best options for drilling into hardened metal. These materials offer exceptional strength, heat resistance, and durability, making them reliable for professionals and DIY enthusiasts.

What Are the Common Bit Point Angles?

Standard bit point angles include 118 degrees and 135 degrees. The 118-degree angle is versatile and suitable for general purposes, while the sharper 135-degree angle is recommended for drilling into more complex materials like stainless steel. For metal drilling, split point angles of 135 degrees or 118 degrees are commonly used for accurate drilling without slipping.

What About Coating and Surface Treatment?

Coating and surface treatment play crucial roles in enhancing the performance and durability of drill bits for metal. Titanium nitride (TiN) coating and black oxide surface treatment are standard options for reducing friction, preventing corrosion, and prolonging the life of the bit. Cobalt surface treatment is also popular for increasing hardness and strength, especially for tougher metals.

What Speed Should a Drill Be Set At?

When drilling into metal, setting the drill at a higher speed is generally necessary to penetrate the material effectively without overheating or dulling the bit. Selecting the appropriate drill bit for metal and maintaining control while drilling to achieve clean and efficient results is essential.

Stocking Up: What Sizes Do I Need?

Essential drill bit sizes for metal drilling include 1/16 inch, 1/8 inch, 3/16 inch, and 1/4 inch for typical applications. For larger holes, having sizes like 3/8 inch and 1/2 inch on hand is advisable. Investing in high-quality drill bits made from durable materials and ensuring the right size for the project will help you confidently tackle metal drilling tasks.
