"ITRD" is a tool for quickly removing broken taps. We will introduce processing examples for hand taps and point taps. With straight groove taps, as the machining depth increases, the tap's land tends to deflect more easily, leading to the generation of tap fragments. Therefore, if you hear unusual noises during the removal process and fragments occur, stop the machining and carefully remove the fragments using a scribing needle or similar tool. 【Processing Conditions】 ■ Tap Size: HT M12X1.5 ■ Work Material: SCM440 ■ Rotational Speed: 459 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.
