1. Product Overview

The VNMG160408 is a premium-grade indexable carbide insert manufactured by Kyocera under grade designation CA515. This insert is engineered specifically for CNC Turning in modern CNC turning centers. Featuring a sharp cutting edge with positive rake angle and polished flank, the VNMG160408 delivers exceptional surface integrity, dimensional accuracy, and extended tool life across a wide spectrum of workpiece materials.

Each insert is precision-ground to ISO tolerances and coated with a multi-layer PVD coating system that enhances wear resistance and reduces friction at the chip–tool interface. The VNMG160408 is the insert of choice for machinists seeking reliable, repeatable performance in high-volume production environments.

2. ISO Designation Breakdown

The model code VNMG160408 follows the ISO 1832 standard for indexable inserts. Each alphanumeric position conveys critical geometric and functional data:

Position	Code	Meaning

2nd Letter	N	Tolerance class: ±0.005" (±0.13 mm) on inscribed circle and thickness
3rd Letter	M	Insert type: Fixed hole with countersink (for clamping)
4th Letter	G	Insert class: One-sided insert with chipbreaker
Size Digits	16	Inscribed circle (IC) diameter: 16.5 mm
Thickness	04	Nominal thickness: 4.76 mm (3/16")
Radius	08	Corner nose radius: 0.8 mm
Chipbreaker		Positive Pressure (PP): Finishing to semi-finishing operations

3. Engineering Dimensions & Geometry

The following table summarizes the critical dimensional and geometric parameters of the VNMG160408 insert:

Parameter	Value	Notes
Inscribed Circle (IC)	16.5 mm	ISO standard measurement
Insert Thickness (S)	4.76 mm (3/16")	Nominal thickness tolerance ±0.025 mm
Corner Radius (rε)	0.8 mm	Nose radius for edge strength and surface finish
Clearance Angle	7°	Positive clearance for reduced friction
Inscribed Circle Tolerance	±0.13 mm	ISO Class N
Thickness Tolerance	±0.13 mm	Consistent seating height
Hole Diameter	Standard countersink	Compatible with standard clamp pins
Weight (approx.)	0.1 kg (per 10 inserts)	Lightweight for high-speed spindles

4. Grade Details — Key Grade Characteristics

Grade CA515 is a high-performance PVD-coated carbide grade developed by Kyocera for universal turning applications. The substrate is a fine-grained tungsten carbide (WC-Co) matrix that provides an optimal balance between hardness and toughness.

Property	Specification	Performance Impact
Substrate	Fine-grained WC-Co	High hardness with excellent toughness
Coating System	PVD TiAlN + TiN multi-layer	Superior heat resistance and low friction
Coating Color	Bronze-Gold	Visual wear indicator
Coating Thickness	2.5–3.5 μm	Balanced wear resistance without edge dulling
Hardness	HRA 92.5	Resists abrasive wear on steel and cast iron
Transverse Rupture Strength	≥ 2,800 MPa	Withstands interrupted cuts and heavy loads
Max Operating Temp	900°C	Stable at high cutting speeds
ISO Application Group	P15–P35, M10–M25, K15–K25	Steel, stainless steel, cast iron

5. Grade Comparison Matrix

Selecting the optimal grade ensures maximum productivity and cost efficiency. The table below compares grade CA515 with adjacent Kyocera grades:

Grade	Substrate	Coating	Hardness	Best For	Speed Range
CA515	Fine WC-Co	PVD TiAlN/TiN	HRA 92.5	Steel, SS, CI	80–250 m/min
CA530	Ultra-fine WC	PVD TiAlN	HRA 93.0	Hardened Steel	60–180 m/min
CA550	Coarse WC	CVD TiCN/Al₂O₃	HRA 91.5	Cast Iron	100–300 m/min
CA510	Fine WC-Co	PVD TiN	HRA 92.0	General Steel	80–200 m/min

Recommendation: Grade CA515 is the ideal all-rounder for mixed-material shops requiring a single grade for steel, stainless steel, and cast iron applications.

6. Chipbreaker Profile

The Positive Pressure (PP) chipbreaker is specifically engineered for Finishing to semi-finishing operations. Its geometry promotes efficient chip curling and evacuation, preventing chip jamming and protecting the workpiece surface.

Attribute	Specification
Chipbreaker Type	Positive Chipbreaker
Geometry	Sharp cutting edge with positive rake angle and polished flank
Key Feature 1	Low cutting forces
Key Feature 2	Excellent surface finish
Key Feature 3	Minimal burr formation
Key Feature 4	Ideal for finishing
Primary Application	Finishing to semi-finishing operations
Recommended Materials	Steel, stainless steel, cast iron

7. Recommended Applications & Workpiece Materials

The VNMG160408 grade CA515 is validated for the following material groups and application scenarios:

Material Group	Examples	ISO Code	Suitability
Carbon Steel	C45, C60, 1045, 1060	P.1–P.3	★★★★★ Excellent
Alloy Steel	42CrMo4, 4140, 4340	P.4–P.5	★★★★★ Excellent

9. Recommended Cutting Conditions

The following parameters serve as starting points. Always optimize for your specific machine, setup, and material condition:

Workpiece Material	Cutting Speed Vc (m/min)	Feed fn (mm/rev)	Depth of Cut ap (mm)	Coolant
Low-Carbon Steel (C<0.25%)	100–180–220	0.10–0.40 mm/rev	1.0–4.0 mm	Wet / MQL
Medium-Carbon Steel (0.25–0.60%)	80–180	0.10–0.40 mm/rev	1.0–4.0 mm	Wet / MQL
High-Carbon Steel (>0.60%)	60–160	0.10–0.40 mm/rev	1.0–4.0 mm	Wet

Gray Cast Iron	90–160–200	0.10–0.40 mm/rev	1.0–4.0 mm	Dry / Wet
Ductile Cast Iron	70–160	0.10–0.40 mm/rev	1.0–4.0 mm	Wet

Note: Reduce cutting speed by 15–20% for interrupted cuts or work-hardened materials. Increase by 10–15% for continuous cuts with stable setups.

10. Operating Guidelines

Tool Setup: Ensure the toolholder seat is clean and free of burrs. Use a torque wrench to tighten the clamp screw to the manufacturer-specified torque (typically 2.5–4.0 N·m).
Run-Out: Maintain maximum tool run-out of 0.02 mm at the cutting edge. Excessive run-out accelerates flank wear and degrades surface finish.
Coolant: Flood coolant is recommended for steel and stainless steel to control thermal cracking. For cast iron, dry machining is acceptable to avoid thermal shock.
Chip Control: Verify chip curling and evacuation during the first pass. Adjust feed rate if chips are not breaking properly.
Edge Inspection: Inspect the insert after each shift for flank wear (VB), crater wear (KT), and notch wear. Replace when VB exceeds 0.3 mm or when surface finish degrades.
Storage: Store inserts in original packaging away from moisture and direct sunlight. Avoid contact with corrosive chemicals.
Safety: Always wear safety glasses and gloves when handling sharp inserts. Dispose of used inserts in designated metal-waste containers.

11. Toolholder Compatibility

The VNMG160408 is compatible with the following standard toolholder families (verify exact insert size and clamping system):

Toolholder Series	Clamping Style	Typical Sizes	Application
SVJBR/L-1616H16	Lever lock / Screw clamp	16×16 to 32×32 mm	External turning
SVQBR/L-2020K16	Lever lock	20×20 to 32×32 mm	External turning, profiling
MVJNR/L-2525M16	Screw clamp	25×25 to 40×40 mm	Heavy-duty turning
MVQNR/L-3232P16	Lever lock	16×16 to 25×25 mm	External turning, facing
DVJNR/L-2020K16	Lever lock / Screw clamp	20×20 to 32×32 mm	Profiling, copy turning

Tip: Use a toolholder with the closest possible approach angle to minimize overhang and maximize rigidity. For internal turning, select the largest possible boring bar diameter that fits the hole.
