Quality is Never an Accident
To achieve the optimal surface finish on the OD of the ER collet, we have to precision grind the collet with the appropriate speed and feed for the right amount of time in the Shigiya grinder. We are not cutting corner in this grinding process time to increase the production. The OD makes contact with the bore on the tool holder and along with the internal bore tolerance it’s critical to be able to maintain the overall runout after a long period of usage.
Craftmanship
-
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
Spotlight
-
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.
