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

⭐⭐⭐⭐ "Reliable Japan Quality" - S. Tanaka, Japan
"Very stable performance on our CNC Swiss machines. Clean slots with no burrs. J740 grade is very tough."

⭐⭐⭐⭐⭐ "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

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.
