Tungaloy Positive Turning Inserts Collection | CCMT DCMT VBMT SCMT TCMT

Tungaloy Positive Turning Inserts Collection

Low Cutting Force | High-Precision Finishing | Professional CNC Solutions

Which positive insert is best for minimizing vibration and achieving high-precision internal bores?

The Tungaloy Positive Turning Insert series is engineered for applications where reducing cutting resistance is critical. Unlike negative inserts, positive geometries (7° or 5° relief angles) feature a sharp cutting edge that "slices" through material rather than pushing it. This makes them the industry standard for internal boring, machining slender workpieces, and achieving superior surface finishes on low-rigidity machines. This collection includes all major ISO shapes—CCMT, DCMT, VBMT, TCMT, and SCMT—available in Tungaloy’s world-class NS9530 Cermet for mirror finishes and T9200 Premium Carbide for high-speed steel turning.

Anti-Vibration Geometry

The positive relief angle drastically reduces radial forces, preventing chatter and "singing" during deep internal boring operations.

NS9530 Gloss Technology

Our Cermet grade remains chemically inert at high temperatures, preventing metal adhesion and ensuring a glossy finish on steel workpieces.

Premium Chipbreakers

From the -PF for fine finishing to -PS for general light-medium turning, these breakers ensure short, manageable chips even in "stringy" materials.

Voice of the Machinist

⭐⭐⭐⭐⭐ "Solved my chatter problems" - Mark S., USA
"Was struggling with vibration on a 12" deep bore. Switched to Tungaloy DCMT positive inserts and the finish came out like glass. Beyond CNC delivered overnight."

⭐⭐⭐⭐⭐ "Genuine Quality" - Hans B., Germany
"Verified original Tungaloy stock. The NS9530 grade is the best cermet I have ever used for stainless finishing."

⭐⭐⭐⭐ "Great price for Tungaloy" - G. Russo, Italy
"Hard to find these prices in Europe for authentic Japanese inserts. Very happy with the CCMT collection."

Technical FAQ

Q: Why should I choose positive inserts over negative ones?

A: Positive inserts require less machine horsepower and produce lower cutting forces. They are essential for thin-walled parts and internal boring where deflection is an issue.

Q: What is the difference between 7° (C) and 11° (P) relief angles?

A: 7° is the standard for most turning. 11° provides even more clearance, often used for very small internal bores or soft materials like aluminum.

Q: Can these be used on Stainless Steel?

A: Yes. Use the **AH series** PVD grades or **PC series** for the best performance in stainless to prevent work hardening.

Industrial Tip: Extension Ratios

When boring with **Positive Inserts**, keep your boring bar overhang within **3-4 times the diameter** for steel shanks. If you must go deeper, ensure you use a carbide-reinforced bar to maintain precision. **BEYOND CNC** - Engineering Excellence.
