CNCQ090504LEP2220 ENGC 9.525mm Square Shoulder Mill Insert

Product Overview

The ENGC CNCQ090504LEP2220 is a square indexable carbide milling insert from ENGC(森泰英格), designed for 90° shoulder milling, face milling, and profiling on CNC machines. It features 0.4 mm corner radius, LE chipbreaker, and EP2220 PVD-coated grade, delivering good surface finish, stable cutting, and long tool life in carbon/alloy steels. Ideal for general‑purpose to medium‑duty milling in mechanical and automotive components.

Key Features

• 90° Square Shape (CNCQ): Positive geometry for shoulder/face milling, light cutting force.
• Size 09: Inscribed circle 9.525 mm, compatible with FM90‑50/63CN09 series cutters.
• 0.4 mm Corner Radius (04): Reduces stress concentration, improves surface quality.
• LE Chipbreaker: Optimized for medium feeds, smooth chip flow in steel.
• EP2220 Grade: PVD TiAlN coating, high wear resistance for steel machining.
• Screw‑Clamped: Rigid mounting in ENGC FM90‑CN09 tool bodies.

Workpiece Materials

• Carbon steels (1045, S355, Q235) – primary
• Alloy steels (4140, 42CrMo4, HRC <42)
• Stainless steels (304, 316, light cuts)
• Cast iron (HT200, HT250, low‑to‑medium feed)

Typical Applications

• 90° shoulder milling and step profiling
• Face milling (medium depth of cut)
• Peripheral milling and slotting
• Semi‑finishing of steel components
• General engineering and automotive parts
