Kyocera WPMT110202HQ CA115P TML00470 - High-Precision Finishing

Product Overview

The WPMT110202HQ is a premium 80° Trigon Insert manufactured by Kyocera under the grade designation CA115P. Engineered for high-precision finishing operations, this indexable carbide insert delivers exceptional dimensional accuracy, superior surface finish, and extended tool life in demanding CNC turning operations. The insert features a 0.2 mm nose radius and is optimized for machining Carbon steel, alloy steel, stainless steel, and cast iron.

ISO Designation Breakdown

Engineering Dimensions & Geometry

The WPMT110202HQ is precision-ground to tight tolerances ensuring consistent seating in standard toolholders. Key dimensional data includes an inscribed circle diameter of 11.0 mm, overall thickness of 2.38 mm, and a corner nose radius of 0.2 mm. The positive rake geometry for reduced cutting forces. These geometric attributes minimize cutting vibration and promote stable chip formation across the recommended parameter window.

Grade Details - Key Grade Characteristics

CA115P PVD Coated Carbide is a high-performance grade featuring:

• Excellent balance of wear resistance and fracture toughness
• Superior resistance to built-up edge (BUE)
• Stable performance in continuous and light interrupted cuts
• Good thermal shock resistance for dry and wet machining
• Optimized for medium to high cutting speeds

The CA115P substrate is paired with a PVD (Physical Vapor Deposition) Multi-layer Coating to create a thermally stable cutting edge capable of maintaining hardness at elevated temperatures generated during high-speed steel machining.

Grade Comparison Matrix

Compared to CA115 (ungraded), CA115P offers improved crater wear resistance and longer tool life in steel machining. It sits between CA110 (roughing) and CA120 (finishing) in the Kyocera grade spectrum.

Chipbreaker Profile

HQ - High-Precision Finishing — Finishing Chipbreaker

Optimized for light cutting depths and low feed rates. Produces superior surface finish with minimal cutting forces. Ideal for final pass operations where dimensional accuracy and surface quality are critical.

Key Chipbreaker Attributes:

• Positive rake geometry for reduced cutting forces
• Excellent chip control for long-chipping materials like steel
• Optimized land width for edge strength and finish quality balance
• Precision-ground peripheral edges for accurate repeatability

Recommended Applications & Workpiece Materials

The WPMT110202HQ CA115P is recommended for the following materials and application types:

• Carbon Steel: Continuous and semi-interrupted turning (C45, C60, 1045, 1060)
• Alloy Steel: Medium alloy steels up to 40 HRC (4140, 4340, 16MnCr5)
• Stainless Steel: Austenitic and martensitic grades (304, 316, 410, 420)
• Cast Iron: Gray cast iron and nodular cast iron (GG25, GGG40)
• Forged Components: Scale-covered surfaces with light interruption

Application Map by Operation

Recommended Cutting Conditions

Low to medium cutting speeds with shallow depths of cut (0.1–1.5 mm) and fine feed rates (0.05–0.20 mm/rev).

Operating Guidelines

• Always verify insert seating and clamping force before starting the spindle.
• Use coolant or cutting fluid for materials prone to work-hardening (e.g., austenitic stainless steels).
• Ensure rigid tooling setup to minimize vibration; use anti-vibration boring bars for deep internal operations.
• Monitor flank wear (VB) and replace inserts when wear reaches 0.3 mm for roughing or 0.15 mm for finishing.
• Index the insert to a fresh edge if chipping, built-up edge, or discoloration is observed.
• For best surface finish, use the highest cutting speed within the recommended range and the lowest stable feed rate.

Toolholder Compatibility

The WPMT110202HQ is compatible with standard ISO toolholders designed for 80° Trigon Insert inserts with a 11.0 mm inscribed circle and 2.38 mm thickness. Recommended toolholder series include:

• External Turning: Standard lever-lock or screw-clamp holders (e.g., MVJNR, MVQNR for V-inserts; MWENR, MWFN for W-inserts)
• Internal Turning: Boring bars with 93° or 107° approach angles (e.g., S16Q-MVJNR, S20R-MWENR)
• Clamp System: Ensure holder chip groove matches insert thickness (2.38 mm) for proper seating
• Coolant Delivery: High-pressure coolant toolholders recommended for chip evacuation in blind-hole boring
