Sumitomo 19T6BPE Turning Insert CCMT32.51ESU AC5025S Carbide

Product Description

The SUMITOMO 19T6BPE is a solid carbide turning insert designed for precision external and internal turning operations. Coated with TiAlSiN via a PVD process under SUMITOMO's proprietary Absotech Bronze designation, this insert delivers thermal resistance and edge stability at elevated cutting temperatures. It carries an ANSI code of CCMT32.51ESU and ISO code CCMT09T304N-SU, with an 80-degree diamond shape, a 0.0156-inch corner radius, and a 3/8-inch inscribed circle. The ESU chip breaker geometry and positive rake angle of 8 degrees support efficient chip control in demanding applications. This insert is installed by CNC machinists and tooling technicians in production turning environments.

The 19T6BPE is rated for primary use on superalloys (Material Grade S20), making it well-suited for aerospace, power generation, and high-temperature alloy components that demand consistent tool life and tight tolerances. The neutral cutting direction provides flexibility across a range of turning setups. It is sized at 0.3819 inches in length with a 0.1732-inch hole diameter for screw-type insert holding, fitting standard CCMT-style toolholders used in CNC lathes and turning centers across production and job-shop environments.

Key Features

• TiAlSiN PVD coating (Absotech Bronze) for thermal stability and wear resistance in superalloy cutting
• 80-degree diamond insert shape with positive rake for reduced cutting forces
• ESU chip breaker geometry optimized for controlled chip formation
• Screw-type holding method (CCMT style) for secure, repeatable seating in compatible toolholders
• Neutral cutting direction supports flexible toolholder orientation
• Meets ANSI and ISO 13399 standards for tooling data interoperability

Compatibility

Designed for use in standard CCMT-style screw-lock turning toolholders. ANSI code CCMT32.51ESU and ISO code CCMT09T304N-SU identify compatible toolholder pockets. Verify toolholder insert pocket geometry and clamp style before installation.

Installation Notes

Installation is performed by qualified CNC machinists or tooling technicians. Power down and lock out the machine spindle before changing inserts. Use the appropriate torx or hex key to the toolholder manufacturer's specified clamp screw procedure. Inspect the insert pocket and seating surface for debris or damage before seating the insert to ensure proper contact and edge alignment.
