Tungaloy CTD Series Parting & Grooving Inserts

Precision Parting | AH725 & T313W Grades | Made in Japan

What are the best inserts for high-stability grooving and parting?

The Tungaloy CTD Series (CTD3, CTD4, CTD5) represents a highly versatile solution for precision machining in parting and deep grooving applications. Available in the high-toughness AH725 PVD grade and the wear-resistant T313W CVD grade, these inserts are engineered to provide exceptional surface finishes and dimensional accuracy. Whether you are performing CNC machining on carbon steel, alloy steel, or stainless steel, the CTD geometry ensures efficient chip evacuation and minimal vibration. These indexable turning tools are designed for maximum stability in narrow-width cutting, significantly extending tool life in high-volume production environments. By choosing these long-tail keywords optimized grooving inserts, you ensure a cost-effective and reliable manufacturing process.

CTD5 5.0 mm ~0.197" AH725

How do I choose between AH725 and T313W?

The AH725 Grade is a versatile PVD coated grade designed for general machining across multiple materials, including stainless steel. It offers a great balance of wear resistance and toughness, making it the primary choice for precision machining under various conditions. The T313W Grade, a premium CVD grade, is optimized for higher cutting speeds in steel turning. It features enhanced heat resistance and flank wear resistance, making it ideal for stable, high-production CNC machining. Selecting the right parting and grooving insert grade is crucial for minimizing downtime and maximizing output.

Recommended Cutting Parameters

  • AH725 Cutting Speed (Vc): 80 - 180 m/min
  • T313W Cutting Speed (Vc): 120 - 240 m/min
  • Feed Rate (f): 0.05 - 0.20 mm/rev (Depending on width)

*Pro Tip: For deep parting operations, ensure high-pressure coolant is directed exactly at the cutting edge to avoid chip jam.*

What our Global Customers are saying

⭐⭐⭐⭐ "Very Stable" - Alan L., Canada
"The CTD4 width is perfectly consistent. No vibration even during deep grooving cycles. Reliable and worth the price."

⭐⭐⭐⭐⭐ "Predictable Performance" - Kenji O., Japan
"Tungaloy standard quality. If you want a trouble-free parting process, the CTD series is the safe bet. AH725 works for everything."

⭐⭐⭐⭐⭐ "Great Value" - Sanjay P., India
"Original Tungaloy stock at a very competitive price. Parting 4140 steel has never been smoother with the CTD5."

Technical Parting & Grooving Q&A

Q: Can I use CTD inserts for side-turning?

A: While primarily designed for radial grooving and parting, these inserts can perform light side-turning. However, for dedicated longitudinal turning, a specific turning insert is better.

Q: What tool holder is required for the CTD series?

A: These inserts are compatible with Tungaloy's dedicated grooving tool holders (e.g., CTDR/L series). Always check the seat size for a perfect fit.

Q: Is AH725 better for interrupted cuts?

A: Yes. The PVD coating and tougher substrate of AH725 make it more resilient to the physical shocks of interrupted cutting compared to CVD grades.

Expert Tooling Tip: Grade Optimization

For stainless steel, prioritize AH725 for its coating adhesion and toughness. For high-speed carbon steel production, T313W will provide the wear resistance needed to maintain cycle times and precision throughout the shift.

Technical FAQ & Buying Guide

Are your carbide inserts interchangeable with major brands like Sandvik, Iscar, or Kennametal?

Absolutely. Our CNC carbide inserts (including CNMG, WNMG, DNMG, and APMT series) are manufactured strictly adhering to international ISO/ANSI specifications. A CNMG 120408 from OYYU BEYOND will flawlessly fit any standard turning tool holder or indexable tool from major global brands like Sandvik Coromant, Kennametal, Iscar, Walter, or SECO, providing a highly cost-effective premium alternative without sacrificing tolerance or tool life.

How do I choose the correct insert grade and chipbreaker for machining Stainless Steel (M) vs. Carbon Steel (P)?

We offer optimized CVD and PVD multi-layer coatings for different ISO material groups:

  • For Carbon/Alloy Steel (ISO P): Choose our thick multi-layer CVD coated grades (e.g., Al2O3 + TiN). They provide exceptional crater wear resistance and thermal barriers during high-speed dry or wet roughing.
  • For Stainless Steel (ISO M): Choose our nano-structured PVD coated grades with sharp, positive chipbreakers (like -TM or -MA). This combination prevents work hardening and effectively controls sticky chips.
What are the recommended cutting speed (Vc) and feed rate (f) parameters to maximize tool life?

The optimal cutting parameters vary depending on the workpiece hardness and operation type:

  • For General Steel Turnings: Recommended cutting speed ($V_c$) ranges from 150 to 280 m/min, with a feed rate ($f$) of 0.15 to 0.45 mm/rev.
  • For Stainless Steel Finishing: Recommended cutting speed ($V_c$) is 120 to 200 m/min, with a feed rate ($f$) of 0.10 to 0.25 mm/rev.Always adjust parameters based on early wear patterns: increase $V_c$ if built-up edge occurs, or reduce $V_c$ if severe flank wear is observed.
Do you offer bulk discounts or wholesale pricing for machine shops and distributors?

Yes, we support machine shops, distributors, and global buyers with tiered wholesale pricing and competitive volume discounts. We also provide OEM custom manufacturing solutions for tool holders and carbide inserts based on your technical drawings. Contact our team to request a quick B2B quotation.

What is your international shipping policy and typical lead time for orders?

We provide secure worldwide express shipping (via DHL, FedEx, and UPS) with specialized, vibration-proof industrial packaging to ensure tools arrive in perfect condition. In-stock items are dispatched within 24-48 hours, while custom or bulk orders typically have a stable lead time of 15-25 days.
