HIGH HARDNESS These taps are made of high speed steel and their surface is finished by nitriding for high hardness and rust resistance. COMBINATION DRILL No more using a drill to drill the hole, and then tapping it later with another tool. TAPS BIT SET Thread: M3, M4, M5, M6, M8, M10, Pitch: 0.5mm, 0.7mm, 0.8mm, 1.0mm, 1.25mm, 1.5mm, for tapping various threads. EASY TO USE Each tap drill bit is engraved with its convenient size so you can choose the appropriate size at a glance. A tapered end on the hex shank can prevent excessive shock. NOTE The taps are designed with spiral flutes and the chip removal process would be better. Description: Tapping bits increase the efficiency of the operation by allowing drilling and tapping in a single pass. These HSS drill bits and bits are excellent tools used to create screw threads, to cut or form the female part of the mating pair. They are used on a machine to do the tapping, such as a lathe. Tapping with these taps is faster and generally more accurate because human error is eliminated. Features: These taps are made of high-speed steel and their surface is finished by nitriding for high hardness and rust resistance. There are a total of 6 pieces of taps in different sizes ranging from M3 to M10 that you can use to tap different threads. The taps are designed with spiral flutes and the chip cleaning process would be better. These are taps with drilling function, used to drill a hole and cut new threads at the same time, you will have a smooth tapping experience with them. These taps are used on a machine to perform tapping, which is generally more accurate because human error is eliminated.
