KORLOY TECH-NEWS - English Double-sided round milling tool with 8 corners ҁ The exclusive structure preventing rotation ensures stable machining. ҁ Double-sided round tool with 8 corners realizes cost efficiency.

Double-sided round milling tool with 8 corners KORLOY has released RMR, the most efficient 8-corner double-sided round milling tool for the machining market, including mold and aerospace industries. RMR is a tool with double-sided 8-corner that enhances cost-effectiveness compared to singlesided tools. It features a unique anti-rotation structure with improved stability, reducing the risk of unexpected breakage and chipping, resulting in a longer tool life. In addition, with its compact C/B and helix-shaped cutting edge, RMR exhibits excellent cutting performance even in high feed cutting operations....

For the safe metalcutting Use safety supplies such as protective gloves to prevent possible injury while touching the edge of tools. Use safety glasses or safety cover to hedge possible dangers. Inappropriate usage or excessive cutting condition may lead tool's breakage or even the fragment's scattering. Clamp the workpiece tightly enough to prevent its movement while its machining. Properly manage the tool change phase because the inordinately used tool can be easily broken under the excessive cutting load or severe wear, and it may threat the operator's safety. Use safety cover because chips...
