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.

CTD3 3.0 mm ~0.118" AH725 / T313W
CTD4 4.0 mm ~0.157" AH725 / T313W
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

⭐⭐⭐⭐⭐ "Excellent Parting Finish" - David R., UK
"Switched to CTD3 AH725 for stainless steel parting. The chips break beautifully and the tool life is nearly double our previous brand."

⭐⭐⭐⭐⭐ "Speed and Accuracy" - Markus S., Germany
"Using the T313W for high-speed steel grooving. Very predictable wear and incredible thermal resistance. Great Japan-made tools."

⭐⭐⭐⭐ "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

How do I choose the correct specification?

When choosing CNC cutting tools, check the full model code, dimensions, grade and selected variant before ordering. Do not rely on the product image alone.

How can I check compatibility with my existing setup?

For carbide inserts, tool holders, drills and end mills, compare the mounting dimensions, connection type and manufacturer's specifications with your holder or machine. If you are unsure, share your existing part number and machining application with us before ordering.

What quantity and price unit am I ordering?

Check the product listing for the selling unit, pack quantity and included components. If it is unclear whether the price is per piece or per pack, or whether a tool body and inserts are sold separately, contact us before purchasing.

How should I choose cutting parameters?

Select cutting speed, feed rate and depth of cut using the relevant manufacturer's recommendations for your tool model, workpiece material, machine conditions and coolant method. The same settings are not suitable for every product or application.

Are bulk discounts available?

Our automatic quantity discount is 6% off for 2–9 items and 12% off for 10 or more items, based on the total product quantity in the cart. Other offers may not combine with this discount; check the applicable offer conditions.

When will my order ship and arrive?

According to our shipping policy, orders are typically processed and shipped within 1–3 business days after confirmation. Delivery generally takes 5–20 business days, depending on your destination and shipping method. Customs clearance or unforeseen delays may affect delivery times.
