Korloy VN Series 35° Diamond Turning Inserts | VNMG VNMP VNMA for Steel & Stainless

Korloy VN Series 35° Diamond Turning Inserts

High-Precision Finishing | Versatile ISO Geometry | Premium PVD & CVD Grades

Which 35° diamond insert is best for intricate profiling and superior surface finish?

The Korloy VN Series is the professional choice for profiling, undercutting, and fine finishing. The 35° diamond shape (V-shape) provides the necessary clearance for complex geometries that 80° (C) or 55° (D) inserts cannot reach. Featuring Korloy's advanced PC9030 and NC3225 grades, this collection excels in both stable and interrupted cutting. Whether you are using VNMG for general steel or VNMP for specialized positive raking, our Korloy collection ensures minimal vibration and maximum chip control.

Multi-Layer Coatings

Korloy’s PVD (PC series) and CVD (NC series) coatings provide extreme heat resistance, allowing for higher cutting speeds while preventing crater wear in stainless and carbon steels.

Optimized Profiling

The slim 35° profile reduces radial cutting forces, which is essential for machining long, slender workpieces where deflection and chatter are constant risks.

Superior Chip Control

Available with various chipbreakers (e.g., VF for finishing, VP for medium), designed to break chips into short, manageable segments even at light depths of cut.

Global Machinist Feedback

⭐⭐⭐⭐⭐ "Perfect for Profiling" - James H., USA
"The clearance on the Korloy VN series is unbeatable. Switched to PC9030 for our stainless jobs and tool life increased by 30%."

⭐⭐⭐⭐⭐ "Excellent Surface Finish" - Klaus M., Germany
"Using the VNMG 160404 for final passes on alloy steel. Surface Ra is consistently within spec. Very reliable."

⭐⭐⭐⭐ "Great for the price" - Marco F., Italy
"Good performance on our medium carbon steel components. Chips break cleanly even at low feed rates."

Technical FAQ

Q: Can I use VNMG inserts for roughing?

A: The 35° shape is thinner and more delicate than 80° shapes. While light roughing is possible, the VN series is primarily designed for finishing and profiling.

Q: What is the difference between VNMG and VNMP?

A: VNMG is a negative insert for double-sided use, while VNMP usually has a positive rake for reduced cutting force, ideal for thin workpieces.

Q: Is PC9030 suitable for dry cutting?

A: For stainless steel, coolant is highly recommended. However, the PC9030 coating handles thermal shock well if light dry cutting is necessary.

Material Selection Tip

When machining **Stainless Steel**, prioritize the **PC9030 (PVD)** grade to prevent built-up edge. For high-speed **Steel** production, the **NC3225 (CVD)** grade offers the best wear resistance. **BEYOND CNC** - Your Partner in Precision.
