Carbide DNMG150608 Turning Insert

Model Segment	Definition & Technical Significance
DNMG	DNMG carbide turning insert
15	Insert Size Code: 15mm nominal cutting edge length
06	Insert Thickness: 6.35mm (0.25 inches), balancing rigidity and load-bearing capacity
08	Corner Radius: 0.8mm (reduces chipping risk, improves surface finish, and distributes cutting pressure evenly)

Core Advantages

Carbide PDJNR2525M15 Tool Holder Advantages
Full Carbide Construction: Crafted from high-purity WC-Co carbide (HRA 92-93), the tool holder offers superior hardness and wear resistance compared to steel holders. It resists deformation and wear even under high cutting loads (up to 12kN axial force), ensuring long service life and consistent positioning accuracy.
High Rigidity & Stability: 25×25mm rectangular carbide shank provides exceptional rigidity, minimizing vibration and tool deflection during heavy-duty turning. The precision-machined insert pocket (±0.003mm positioning accuracy) ensures the DNMG150608 insert aligns perfectly, maintaining dimensional stability across batch production.
Coolant Compatibility: Equipped with a built-in coolant channel and nozzle mount, directing high-pressure coolant (up to 15 bar) to the cutting edge. This reduces insert temperature, prevents built-up edge (BUE), and extends tool life.

Carbide DNMG150608 Insert Advantages
Premium Carbide Substrate: Made from micrograin WC-Co carbide (ISO grade P20-P40/K20-K30), balancing hardness (HRA 92.5) and toughness. It withstands shock loads and interrupted cuts, making it suitable for cast iron and alloy steel machining.
Multi-Edge Design: 4 usable cutting edges (double-sided) reduce per-part tool costs by 30% vs. single-sided inserts. Ideal for high-volume production, as each insert can be indexed 4 times before replacement.
Efficient Chip Control: General-purpose "G" chip-breaker groove design accelerates chip evacuation, even at high feed rates. Prevents chip clogging and re-cutting, reducing heat buildup and workpiece damage.
0.8mm Corner Radius: Enhances edge strength, reduces chipping risk, and delivers smooth surface finish (Ra ≤1.2μm). Perfect for semi-finishing and finishing operations requiring precision.

 

Application Scenarios
External turning and square shoulder machining of 45# steel automotive shafts and engine components.
Semi-finishing and finishing of 304 stainless steel valve bodies and chemical equipment parts.
Interrupted cutting of QT450 cast iron pulley hubs and machine tool bases.
Contour turning of 40Cr alloy steel hydraulic cylinders and gear shafts.
