Collection: Drill Bit Sets

A drill bit set is a collection of various drill bits designed to create holes in different materials like wood, metal, and masonry. These sets typically offer a range of sizes and sometimes include specialized bits for specific applications.

Drill bits within a set are usually made from different types of materials, such as high-speed steel (HSS), cobalt steel, or carbide, to accommodate the varying hardness of the materials they'll be drilling into. HSS bits are a good choice for drilling softer materials, while cobalt bits are better suited for harder metals like stainless steel. Carbide-tipped bits are designed for masonry and other hard materials. 

Many drill bits also feature coatings, such as black oxide or titanium nitride, to enhance their performance and longevity. These coatings can improve corrosion resistance, reduce friction, and increase durability. Black oxide is good for iron and steel but not recommended for aluminum, magnesium, or similar materials. Titanium nitride, which is a gold-colored coating, can increase hardness and provide a thermal barrier, making it suitable for harder materials. 

The types of drill bits commonly found in sets include:
