Tungaloy JTGR3180F J740 Grooving Insert

High-Precision 1.8mm External Grooving | PVD J740 Carbide | Made in Japan

What is the best 1.8mm insert for narrow grooving in titanium and stainless?

The Tungaloy JTGR3180F J740 is a high-performance indexable grooving tool specifically engineered for precision external grooving operations. Utilizing the industry-leading J740 PVD coated carbide grade, this insert provides exceptional wear resistance and edge toughness when machining difficult materials like 304/316 stainless steel, heat-resistant alloys, and titanium. The 1.8mm cutting width (CW) and F-type chipbreaker (Flat geometry) ensure superior chip evacuation and edge sharpness, which is critical for preventing built-up edge (BUE) in CNC machining. As an authentic Japan-made grooving insert, it is the professional choice for maintaining tight tolerances and superior surface finish Ra 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
  • Coolant: High-pressure coolant is strongly advised for 1.8mm narrow grooves.

*Pro Tip: Ensure tool center height is precisely aligned to prevent vibration and uneven wear. J740 provides excellent toughness for interrupted cuts.*

Global Verified Customer Reviews

⭐⭐⭐⭐⭐ "Standard for 1.8mm Slots" - Heinrich K., Germany
"The JTGR3180F J740 is my standard choice for 1.8mm snap ring grooves. Stable, predictable, and clean."

⭐⭐⭐⭐ "Great for Aerospace" - Michael B., USA
"Used on Swiss-style lathes for titanium components. The F geometry handles chips perfectly with no tangling."

⭐⭐⭐⭐⭐ "Superior Edge Strength" - Alessandro B., Italy
"J740 grade doesn't chip easily on interrupted cuts. Better than several other European brands I've tried."

⭐⭐⭐⭐⭐ "Fast Shipping & Genuine" - S. Clarke, UK
"Best price for genuine stock. The 1.8mm width is held with extreme precision across the entire batch."

Technical Tooling Q&A

Q: Is JTGR3180F suitable for high-speed parting?

A: This is specifically an external grooving insert. While it can perform light parting-off on small diameters, its flat geometry (F) is optimized for precision 1.8mm grooves.

Q: Which tool holder do I need for this 1.8mm insert?

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

Q: Why use J740 over CVD grades for narrow grooving?

A: J740 (PVD) provides a sharper cutting edge and higher toughness, which is critical for narrow grooving where vibration is more likely than in heavy CVD turning.

Expert Insight: PVD vs. CVD in Grooving

In precision machining, J740 represents the peak of edge toughness. While CVD coatings are optimized for high-volume steel roughing, J740 provides the sharp stability needed for the narrow slotting cycles of CNC grooving. Protect your indexable grooving tool with proper coolant 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.
