Sumitomo 14HAW18 Round Milling Insert ACP200 Carbide

Product Description

The SUMITOMO 14HAW18 is a round solid carbide milling insert in manufacturer grade ACP200 with a PVD-applied coating. It carries insert style QPMT and size code 4312, with an inscribed circle of 0.5000 inches and a thickness of 0.1875 inches. Designed for precision milling operations, the insert delivers controlled cutting geometry and wear resistance suited to high-demand metal-removal applications. Licensed HVAC or machining professionals running face mills, shoulder mills, or copy mills will find this insert a direct-fit consumable replacement. Maximum depth of cut reaches 0.2500 inches, making it capable across a range of finishing and semi-finishing passes.

This insert is engineered for primary use in stainless steel and steel workpieces, corresponding to ISO material codes M and P. It is suited to CNC milling centers in both job-shop and production environments where consistent surface finish and dimensional accuracy are required. The ANSI code for this insert is QPMT4312PPEN ACP200, and it is compatible with the WRCX cutter series. Typical applications include contour milling, pocket milling, and face milling on ferrous alloys where a round insert profile helps distribute cutting forces evenly.

Key Features

• Round insert shape distributes cutting loads evenly, extending edge life in interrupted cuts
• PVD coating process preserves sharp edge geometry while improving surface hardness and heat resistance
• 0.5000-inch inscribed circle with a 0.1875-inch thickness fits WRCX cutter series toolholders
• Maximum depth of cut of 0.2500 inches supports both finishing and light semi-finishing passes
• ANSI-standard geometry (QPMT4312PPEN ACP200) ensures interchangeability with conforming toolholders
• Solid carbide substrate provides rigidity and thermal stability in stainless steel and steel milling

Compatibility

Designed for use with the WRCX cutter series. ANSI code QPMT4312PPEN ACP200 confirms fitment in any conforming QPMT-style toolholder built to ANSI standards.

Installation Notes

Installation of milling inserts should be performed by a qualified machinist or tooling technician with the spindle fully stopped and the machine placed in a locked-out, tagged-out state per OSHA lockout/tagout procedures. Use the appropriate Torx or hex key torque wrench specified by the cutter body manufacturer when seating the insert screw — do not use standard drivers that may under- or over-torque the clamp screw. Inspect the insert pocket and clamping surfaces for chips or debris before seating the new insert. Replace inserts as a set when running multi-insert cutter bodies to maintain balanced cutting forces.
