Tungaloy JTGR3175F J740 Grooving Insert

High-Precision 1.75mm External Grooving | PVD J740 Carbide | Made in Japan

What is the best 1.75mm insert for narrow grooving in stainless steel?

The Tungaloy JTGR3175F J740 is a specialized indexable grooving tool designed for high-accuracy external grooving operations. Built with the advanced J740 PVD coated carbide grade, this insert excels in machining difficult-to-cut materials like 304/316 stainless steel, titanium, and heat-resistant alloys. The 1.75mm cutting width (CW) and F-type chipbreaker provide exceptional edge sharpness and chip evacuation, which is critical for preventing built-up edge (BUE) in precision CNC machining. As an authentic Japan-made grooving insert, it is the industry standard for maintaining tight tolerances and superior surface finish Ra, ensuring consistent tool life in high-demand production environments.

Recommended Cutting Parameters (J740 Grade)

  • Cutting Speed (Vc): 40 - 130 m/min (Highly dependent on material hardness)
  • Feed Rate (f): 0.02 - 0.12 mm/rev (Optimize for 1.75mm stability)
  • Coolant: High-pressure coolant is strongly advised for narrow grooving.

*Pro Tip: For precision 1.75mm grooving, ensure the tool holder is perfectly aligned to the center. J740 provides excellent toughness, but alignment prevents vibration.*

Global Verified Customer Reviews

⭐⭐⭐⭐⭐ "Great Chip Control" - Chris B., USA
"No stringy chips. They curl and break perfectly. Reduced our machine downtime significantly."

⭐⭐⭐⭐⭐ "Authentic & Fast" - A. Clarke, UK
"Real Tungaloy stock. Best price for the durability you get. J740 grade doesn't smear the material."

Technical Tooling Q&A

Q: Is JTGR3175F suitable for high-speed parting?

A: This is primarily an external grooving insert. While it can perform light parting-off on small diameters, its flat geometry (F) is optimized for precision 1.75mm grooves.

Q: Which tool holder fits the JTGR3175F?

A: It is designed for Tungaloy J-Series external holders, such as the JCTEL/R series. Ensure the seat size matches the Series 3 inserts.

Q: Why use J740 over CVD grades?

A: J740 (PVD) provides higher edge toughness and sharpness, making it much more reliable for precision grooving in gummy or hard alloys than CVD coatings.

Expert Insight: The Versatility of J740

In precision machining, J740 represents the peak of edge stability. While CVD coatings are optimized for high-volume turning, J740 provides the vibration resistance needed for the narrow slotting cycles of CNC grooving. Protect your indexable grooving tool with proper filtration.

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.

How do you guarantee the quality and tolerance precision of your CNC tools?
