Product Overview

The Kyocera TNMG110408GS CA125P TMK00227 is a precision-engineered 60° triangle negative turning insert designed for general machining. Manufactured in Japan to strict ISO 1832 standards, this insert combines a fine-grained carbide substrate with an advanced TiAlN PVD coating to deliver exceptional wear resistance, thermal stability, and extended tool life in demanding CNC environments.

Whether you are performing external turning, facing, or boring operations, the TNMG110408GS offers optimized chip control through its GS – General Standard geometry, ensuring consistent surface finish and reliable performance across high-volume production runs.

9–10 Digits	08	Corner radius: 0.8 mm
Suffix	GS	GS – General Standard

Engineering Dimensions & Geometry

Accurate dimensional data is essential for tool selection and simulation. All measurements are nominal per ISO 1832:

Parameter	Metric	Imperial
Inscribed Circle (IC)	6.35 mm	1/4″
Thickness (S)	4.76 mm	3/16″
Corner Radius (rε)	0.8 mm	0.0315″
Hole Diameter	3.5 mm	0.138″
Overall Length (L)	11.0 mm	—

Note: Tolerance class M applies to all dimensions above. Actual values may vary ±0.05 mm.

Grade Details – Key Grade Characteristics

The CA125P grade is a versatile, PVD-coated carbide designed for multi-material machining. Its balanced properties make it the go-to choice for job shops and production facilities alike:

Characteristic	CA125P Specification
Substrate	Fine-grained tungsten carbide (WC-Co)
Coating	TiAlN-based multilayer PVD coating
Coating Color	Bronze / Copper
Hardness	HRA 92.5
Transverse Rupture Strength	≥ 3,500 MPa
Thermal Stability	Up to 800°C continuous
ISO Application Groups	P15–P30 (Steel), M15–M25 (Stainless), K15–K25 (Cast Iron)
Wear Resistance	Excellent (★★★★★)
Chipping Resistance	Very Good (★★★★☆)

Grade Comparison Matrix

Selecting the correct grade is critical for maximizing productivity and minimizing cost per edge. Compare CA125P with adjacent grades in the Kyocera portfolio:

Grade	Coating	Substrate	ISO Range	Best For
CA125P	TiAlN PVD	Fine-grain carbide	P15–P30, M15–M25	Steel, stainless steel, cast iron
CA115P	TiAlN PVD	Ultra-fine grain	P10–P20	High-speed finishing in steel
CA325P	TiCN+Al2O3 CVD	Medium grain	P30–P40	Heavy roughing in steel
PR905	TiAlN PVD	Fine-grain carbide	M10–M20	Stainless steel, exotic alloys

Chipbreaker Profile

The chipbreaker geometry directly influences chip formation, cutting forces, and surface integrity. The GS – General Standard profile on this insert is tailored for specific machining regimes:

Property	Specification
Chipbreaker Name	GS – General Standard
Edge Type	Medium cutting
Recommended Feed	0.10–0.40 mm/rev
Recommended DOC	0.5–3.0 mm
Surface Finish	Good
Chip Control	Optimized groove geometry for general machining

Recommended Applications & Workpiece Materials

The TNMG110408GS with CA125P grade is recommended for the following material groups and conditions:

Carbon & Alloy Steels – Ideal for continuous and lightly interrupted cuts in mild steel, medium-carbon steel, and alloy steels up to 45 HRC.
Stainless Steels – Performs well in austenitic and ferritic grades; reduced speed recommended for duplex and precipitation-hardening grades.
Cast Irons – Excellent for gray cast iron (HB 180–260) and ductile cast iron (HB 150–220). Not recommended for chilled cast iron.
Non-Ferrous Metals – Limited application in aluminum and copper alloys; prefer uncoated or polished grades for best results.

Application Map by Operation

Understand where this insert excels within your machining workflow:

Operation	Suitability	Remarks
External Turning	⭐⭐⭐⭐⭐ Excellent	Primary application; stable chip control
Internal Turning (Boring)	⭐⭐⭐⭐☆ Very Good	Use with appropriate boring bar
Facing	⭐⭐⭐⭐⭐ Excellent	Negative geometry ensures rigidity
Profiling	⭐⭐⭐⭐☆ Very Good	Small radius allows fine contours
Grooving / Parting	⭐☆☆☆☆ Not Recommended	Use dedicated groove/parting inserts
Threading	⭐☆☆☆☆ Not Recommended	Use dedicated threading inserts

Recommended Cutting Conditions

Start with the parameters below and optimize based on machine rigidity, workpiece stability, and coolant delivery:

Workpiece Material	Cutting Speed (Vc)	Feed (fn)	Depth of Cut (ap)
Low-carbon Steel (< 0.25% C)	150–250 m/min	0.10–0.40 mm/rev	0.5–3.0 mm
Medium-carbon Steel (0.25–0.60% C)	150–250 m/min	0.10–0.40 mm/rev	0.5–3.0 mm
Alloy Steel (annealed)	150–250 m/min	0.10–0.40 mm/rev	0.5–3.0 mm
Stainless Steel (Austenitic)	100–180 m/min	0.10–0.40 mm/rev	0.5–3.0 mm
Gray Cast Iron (HB 180–220)	130–200 m/min	0.10–0.40 mm/rev	0.5–3.0 mm
Ductile Cast Iron (HB 150–200)	130–200 m/min	0.10–0.40 mm/rev	0.5–3.0 mm

Values are starting recommendations. Adjust based on machine condition, setup rigidity, and coolant pressure. Always begin at the lower end of the speed range for new applications.

Operating Guidelines

Follow these best practices to maximize insert life and machining quality:

Always use adequate coolant flow for chip evacuation and temperature control.
Verify toolholder clamping torque (recommended 2.5–3.5 N·m for M3.5 screw).
Ensure insert seat is clean and undamaged before mounting.
Use positive-rake toolholders for optimal chip control with negative inserts.
Reduce cutting speed by 15–20% when machining hardened steels (> 45 HRC).
For interrupted cuts, reduce feed by 10–15% to prevent edge chipping.
Inspect insert edge after every 30–60 minutes of continuous operation.
Store inserts in original packaging away from moisture and direct sunlight.

Toolholder Compatibility

This insert is compatible with standard ISO toolholders designed for TNMG negative inserts. Recommended series include:

Toolholder Series	Insert Compatibility	Approach Angle
MTJNR/L (93° toolholder)	TNMG-1104	93° / 60° / 117.5°
DTJNR/L (60° toolholder)	TNMG-1104	93° / 60° / 117.5°
PTJNR/L (117.5° toolholder)	TNMG-1104	93° / 60° / 117.5°

Always verify toolholder seat geometry and clamping mechanism before purchase. Use genuine Kyocera toolholders for best performance.
