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
