M16×1.25×130mm Metric Thread tap Extended Extra Long Straight Slot Thread Tapping Dimension HSS Machine taps Repair Tools DRINYOUNG (M16×1.25×130)

• Tap Size:Thread Size:M16×1.25×130mm, Thread Length:32mm/1.26 inch, Overall Length:130mm/5.12 inch ,Shank Width:12.5mm/0.49 inch .
• Function and Application: The extended type tap is mainly used for deep hole tapping and is suitable for processing through holes and blind holes. It can meet the processing requirements for longer threaded holes.
• Material characteristics: It is recommended to use high-speed steel. This material has excellent hardness and toughness, good wear tolerance, stable debris removal, and a relatively extended overall service longevity.
• Structural design: The shank of the tap is lengthened, and a straight flute structure is adopted to facilitate the discharge of debris downward; right-handed cutting, featuring clear tooth shapes, helps to enhance processing efficiency and accuracy.
• Process assistance: It is recommended to use cutting fluid during the processing. This helps to improve debris removal, cooling and lubrication, thereby maintaining processing stability in deep hole and other conditions.

The extended straight-slot tap is a tool specifically designed for machining deep threaded holes. Its extended structure enables it to reach deep holes or concealed areas that are difficult for ordinary taps to access. This type of tap is designed featuring a straight flute. During cutting, the chips mainly flow towards the bottom of the hole. This chip-discharging method gives it good rigidity and makes it suitable for maintaining stability during through-hole processing. However, this also means that in blind-hole processing, the chip-discharging capacity is relatively limited, and increased attention needs to be paid to debris handling. Overall, the extended straight-slot tap is mainly used for processing through threads in deep holes. While ensuring sufficient rigidity, it is necessary to pay attention to the applicable processing conditions.
