3mm ~ 10mm Metric HSS Thread Tap & Drill Set with 1/4" hex shank Thread & Deburr 

these versatile composite drill and self-centering bit tools offer both time and cost savings. They combine the functionality of a tap and a drill in a single tool, with the combined cost being roughly equivalent to purchasing these tools separately. They are particularly well-suited for various applications, including automotive and machinery repairs, production work, or for DIY enthusiasts working on home projects.

With these tools, you can efficiently drill a hole and thread it in a single step, simplifying the process and saving time. Additionally, you can easily reverse the tool to clean the thread. What's more, they come equipped with a countersink feature that allows you to deburr and chamfer the surface after cutting the thread.

Constructed from high-speed steel (HSS), these tools are suitable for working with materials such as iron, brass, copper, aluminum composites, or plastics. They feature a 1/4" (6.35mm) industry-standard hex shank, making them ideal for use with modern cordless drills.

M3 x 0.5
M4 x 0.7
M5 x 0.8
