One of the most important factors to consider when choosing a thread tap drill bit is the material it is made of. High-speed steel (HSS) drill bits are commonly used for general-purpose tapping in materials such as steel, aluminum, and brass. They are durable, heat-resistant, and can be sharpened for extended use. For hard materials like stainless steel or hardened steel, cobalt drill bits are recommended due to their superior hardness and heat resistance.

High-quality drill bits boast robust construction, utilizing premium materials such as cobalt, titanium, or carbon steel, alloyed for enhanced durability and longevity. Their cutting edges are finely honed to exacting standards, enabling them to penetrate tough surfaces smoothly and efficiently, reducing the risk of fractures or skidding. This reliability is paramount where precision holes are required, as in framework joinery or during the installation of electrical conduits.
