Create and Clean Threads With a Tap Drill Bit
A tap drill bit can be attached to your drill to create or repair threaded holes in metalworking. The tapping technique is the first step in the process of securing screws through metal materials and is important when working on heavy-duty machinery.
Tap drill bits come in M2 high-speed steel, carbon steel and high carbon steel to quickly penetrate durable metals or create clean threads. Some tap drill bits can penetrate both ferrous and non-ferrous metals, making them useful if switching between materials such as aluminum and steel. DEWALT offers tap drill bits that can both drill and thread in the same application, saving you time since you don't have to switch between tools.
A drill tap set offers different shapes and sizes depending on the thread needed to secure different screws. Our Drill Bit Buying Guide can help you decide what set is best for the type of work you're doing.
