Applications: For Drills, Reamers, Tap, Rough milling and Carbide Finishing End mills.

Features

  • MER series has larger contact area and shorter overhang length compared to ER series and providing better radial cutting force. High speed bearing nut design offers stronger clamping force than standard ER nuts, ensuring machining stability for high speed and precision cutting. Recommended with ER-E collet for end mills to achieve the best results. MER series is balanced at 30,000 r.p.m G2.5, ensuring stable performance for high speed.
