SUJ2 alloy steel from Japan Made from SUJ2 alloy steel from Japan which is equivalent to AISI 52100 and hardened to HRC 46-48 Mirror Finished The 2 taper surfaces are precision ground in a CNC grinder Shigiya from Japan to roughness tolerance of Ra 0.4 Taper Accuracy An ER collet is selected during the CNC grinding process to check the 2 taper contact surface's accuracy Robotic Automation in Manufacturing We optimize our manufacturing workflow for both efficiency and accuracy by utilizing robotic arms to load and unload ER collet stock into the Shigiya CNC grinders which are made in Japan. Combining the robotic arms with a reliable CNC grinder is our formular to control tight tolerance in a mass production environment. Compatible with Standard Tap Square design slot in the rear end of the collet locks flat-sided shank, preventing the tap from spinning inside. Bore size and square size are laser marked on the collet body for easy identifying tap size. Made in TAIWAN
