Kyocera WPMT110202HQ CA125P TMK00470

Product Overview

The WPMT110202HQ CA125P from Kyocera is a premium trigon insert engineered for high-performance CNC machining. Designed to deliver exceptional surface finish, dimensional accuracy, and extended tool life, this insert is ideal for cnc turning & facing operations across a wide range of ferrous materials. The CA125P grade features a PVD multi-layer coating (TiAlN-based) that provides superior wear resistance and thermal stability, ensuring consistent performance even under demanding cutting conditions.

With its 11° (P) clearance angle and HQ chipbreaker geometry, the WPMT110202HQ minimizes cutting forces, reduces heat generation, and ensures reliable chip evacuation—critical for unattended CNC production runs.

ISO Designation Breakdown

The WPMT110202HQ designation follows the ISO 1832 standard for indexable inserts. Each character defines a critical geometric or tolerance parameter:

Engineering Dimensions & Geometry

Grade Details – Key Grade Characteristics

The CA125P grade is a PVD-coated carbide grade specifically developed for machining steel and stainless steel workpieces. It combines a fine-grained tungsten carbide substrate with a multi-layer PVD coating (TiAlN + TiN) to achieve an optimal balance of hardness, toughness, and thermal stability.

• Substrate: Fine-grained WC-Co (6% Co) with high hardness and excellent transverse rupture strength
• Coating: Multi-layer PVD TiAlN/TiN (≈ 3-4 μm total thickness) for enhanced wear resistance and reduced friction
• Hardness: 1,620 HV (Vickers) – suitable for medium to high cutting speeds
• TRS: 2,800 MPa – high edge integrity under intermittent cutting and heavy loads
• Oxidation Temperature: 900°C – maintains coating integrity at elevated temperatures
• Color Code: Bronze/Copper (industry-standard PVD TiAlN visual identification)

Recommended Cutting Conditions

The following parameters are recommended starting values for continuous cutting of carbon steel (C45) with the WPMT110202HQ CA125P. Adjust based on machine rigidity, workpiece condition, and desired surface finish.

Operating Guidelines

• Coolant Recommendation: High-pressure coolant (70-100 bar) is recommended for chip evacuation and thermal management, especially in deep cavity turning and stainless steel applications.
• Tool Overhang: Minimize tool overhang to maintain rigidity. Keep the overhang-to-diameter ratio below 4:1 to prevent chatter and vibration.
• Edge Preparation: The WPMT110202HQ comes with a honed T-land edge preparation (0.03-0.05 mm × 20°) for enhanced edge stability. Do not re-hone without proper equipment.
• Insert Seating: Ensure the insert seat and pocket are clean and free of chips before clamping. Use a torque-calibrated key for consistent clamping force.
• Speed Ramp-Up: When starting a new job, begin at 70% of the recommended Vc and gradually increase while monitoring tool wear and surface finish.
• Tool Life Monitoring: Expected tool life under continuous cutting: 15-25 minutes. Monitor flank wear (VB max = 0.3 mm) and replace before catastrophic failure.

Toolholder Compatibility

The WPMT110202HQ is compatible with the following ISO-standard toolholder families. Ensure correct pocket geometry and clamping mechanism for safe operation:

• Recommended Toolholders: WTJNR, WTJNL, WTBNR, WTBNL, MTJNR, MTJNL (for 80° trigon inserts)
• Clamping Type: Lever-lock or screw-clamp mechanisms with top clamp (for inserts with hole)
• Toolholder Material: Alloy steel (42CrMo4) with hardness 42-48 HRC
• Insert Seat Angle: Must match insert clearance angle (11° (P))
