Te c h n o l o g y Reduces the risk of breaking off inside By using a tool with a diameter smaller than the inside diameter of the thread, cutting chips are smaller and chip evacuation is improved. The risk of the tool breaking off inside the hole is reduced as a result. One tool - various types of thread milling Right hand, left-hand and fine thread milling can be performed by just changing the NC program. The nominal diameters of the coarse threads and fine threads that can be processed with the same tool are different. (Example: For ET-1.25-16-PN, coarse thread is M8 × P1.25 and fine...
