110 Series

View Speeds and Feeds for this series

The 110 Series is Sonic's 3-flute solid carbide square end mill for steel, iron, titanium, and nickel alloys. Three flutes leave more chip room than a 4-flute, and Sonic shapes them to clear chips in slotting. Every 110 has a small R0.004"–0.008" (0.1–0.2 mm) radius to protect the corner.

Sonic offers the 110 in TiAlSiN for hardened steels, nickel alloys, and titanium alloys. Sonic grinds every shank to h6 for precision holders and leaves a ground finish, not a polished one, so the shank resists slipping. Every tool is engraved with its lot number for traceability.
