Sumitomo 14T9BBW Milling Insert ACP3000 Carbide Trigon

Product Description

The SUMITOMO 14T9BBW is a solid carbide trigon milling insert designed for indexable face and shoulder milling operations. Manufactured to the WNMU0807 insert style with an ACP3000 Absotech PVD coating, this double-sided insert delivers six usable cutting edges per unit, extending tool life between changeovers. It carries a 1.60 mm corner radius, a thickness of approximately 7.00 mm (0.276 inches), and an inscribed circle of 13.00 mm (0.512 inches). The maximum depth of cut is 3.00 mm (0.118 inches). It is held by screw clamping and is intended for installation by machinists and tooling technicians in production or job-shop environments.

This insert is part of the DMSW cutter series and is suited for use across a broad range of workpiece materials, including steels (P), stainless steels (M), cast irons (K), non-ferrous materials (N), hardened materials (H), and superalloys (S). It is a right-hand cutting insert with a chip breaker designation of H. Typical applications include milling operations on CNC machining centers where consistent edge performance and coating durability are required across varying material types.

Key Features

• ACP3000 Absotech PVD coating for wear resistance across multiple material groups
• Double-sided insert with 6 total cutting edges for extended index life
• Trigon (WNMU) insert shape with screw-clamp holding method for secure seating
• 1.60 mm corner radius reduces insert chipping at entry and exit
• Compatible with DMSW cutter series for consistent system integration
• Right-hand cut with H chip breaker geometry for controlled chip evacuation

Compatibility

Designed for use with SUMITOMO DMSW series milling cutter bodies. ANSI code WNMU0807ZNER-H-ACP3000 confirms fitment within that toolholder family.

Installation Notes

Insert installation and indexing should be performed by a qualified machinist or tooling technician. Power down and lock out the spindle before removing or seating any insert. Use the correct torque wrench and insert screw specified by the cutter body manufacturer — do not overtighten or substitute fasteners. Inspect the cutter pocket seat for debris or damage before installing a new insert to ensure proper seating and runout.
