Introducing examples of machining when removing a broken spiral tap!
The "ITRD" is a tool designed for the quick removal of broken taps. Here, we present a machining example using a spiral tap. When a tap is twisted, the tap's land is wrapped around the internal thread, making it difficult to move even during removal, and it is less likely for fragments of the tap to come out during the process. 【Machining Conditions】 ■ Tap Size: SP M12X1.75 ■ Work Material: S50C ■ Tool Used: ITRD Dc8.5 ■ Rotational Speed: 450 min-1 ■ Feed Rate: 3 mm/min (Step 0.3 mm) *For more details, please refer to the PDF document or feel free to contact us.
