Product Overview
The WNMG06T308HQ is a premium-grade cnc turning insert from Kyocera, featuring the advanced CA525 PVD-coated carbide substrate. This WNMG negative insert with 0.8mm corner radius and high-precision finishing geometry (HQ) is engineered for high-precision finishing for steel and stainless. The 6.35mm inscribed circle and 3.18mm thickness provide excellent edge stability and chip control across a wide range of cutting parameters. Ideal for modern CNC turning centers requiring consistent tool life and dimensional accuracy.

Chipbreaker Profile
HQ Chipbreaker – Precision finishing geometry with narrow land and positive rake angle. Optimized for low cutting forces and superior surface finish at light depths of cut.
| Parameter | Range |
|---|---|
| Recommended Feed (fn) | 0.05 – 0.25 mm/rev |
| Depth of Cut (ap) | 0.1 – 1.5 mm |
Recommended Applications & Workpiece Materials
The WNMG06T308HQ grade CA525 is suitable for the following materials:
- Carbon steel, alloy steel, stainless steel (austenitic), bearing steel, pre-hardened steel (30-50 HRC)
- Hardness range: ≤ 350 HB (optimal), up to 45 HRC with reduced parameters
- Surface condition: Pre-machined, as-cast, or as-forged (roughing geometries)
Application Map by Operation
Recommended machining operations for the HQ geometry:
- Precision external turning, finish facing, contouring, final sizing, thread pre-machining
Recommended Cutting Conditions
Starting parameters for HQ geometry with CA525 grade. Adjust based on machine rigidity and workpiece condition:
| Workpiece Material | Cutting Speed Vc (m/min) | Feed fn (mm/rev) | Depth of Cut ap (mm) |
|---|---|---|---|
| Carbon Steel (≤ 300 HB) | 180 – 280 | 0.05 – 0.25 mm/rev | 0.1 – 1.5 mm |
| Alloy Steel (300-400 HB) | 120 – 200 | 0.05 – 0.25 mm/rev | 0.1 – 1.5 mm |
| Stainless Steel (AISI 304/316) | 100 – 160 | 0.05 – 0.25 mm/rev | 0.1 – 1.5 mm |
| Cast Iron (GG25/GGG40) | 150 – 220 | 0.05 – 0.25 mm/rev | 0.1 – 1.5 mm |
| Tool Steel (40-50 HRC) | 60 – 100 | 0.05 – 0.15 | 0.2 – 0.8 |
Operating Guidelines
- Toolholder Selection: Use negative rake toolholders (e.g., WNMG holders) with 0° or 5° inclination for optimal performance.
- Coolant Recommendation: High-pressure coolant (70+ bar) recommended for chip evacuation in deep cavities and stainless steel.
- Edge Preparation: CA525 features honed T-land edge preparation (0.02-0.05mm) for improved edge stability.
- Run-in Procedure: Reduce cutting speed by 20% for the first 5 minutes to stabilize the coating and substrate interface.
- Tool Life Monitoring: Monitor flank wear (VB). Recommended tool change at VB = 0.3mm for roughing, VB = 0.15mm for finishing.
- Chip Control: Ensure chipbreaker geometry matches feed rate. Adjust coolant nozzle to direct flow at the cutting zone.
