13-piece set of taps, combination drill bits, 6mm HSS M3-M10 drill bits, and SAE 6-32NC to 1/4-20NC dies for drilling, tapping, and milling iron, aluminum, and copper.

High-Strength Material: Made of high-speed steel (HSS) with excellent hardness and wear resistance. It not only remains sharp during high-speed cutting but also resists thermal deformation and extends service life.

All-in-One Drilling and Tapping: The 3-in-1 combination drill and tap set can perform drilling, tapping, and countersinking of holes. Three processes in one, one-step operation, saves many work steps, improves work efficiency, and delivers precise processing results. Used to create threaded holes, ideal for situations where drilling and tapping are required.

Combination Drills and Taps: The drill set includes 12 different tap sizes that cover common metric sizes (M3×0.5 to M10×1.5) and SAE imperial sizes (1/4-20NC to 6-32NC).

In addition, it is specially equipped with a 1/4" quick-change adapter for connecting different tools quickly and easily. Suitable for hand drills, impact drills, drill presses, power screwdrivers, and other taps. Easy to use wet and dry: Whether dry drilling or wet cooling, this kit can be easily managed. Dry drilling is suitable for quick and convenient processing scenarios, while wet cooling can effectively reduce the cutting temperature, reduce tool wear, and extend tool life. Widely used: These taps are indispensable if you do a lot of manufacturing; you can use them in aluminum, plastic, wood, and other thin and soft materials. When using it, make sure it is perfectly straight, take your time, work slowly, and use lubricant to prevent the bit from breaking in the hole.
