Tungaloy JTGR3110F J740 Grooving Insert

High-Precision 1.1mm External Grooving | PVD J740 Carbide | Made in Japan

What is the most accurate insert for 1.1mm grooving in titanium?

The Tungaloy JTGR3110F J740 is an elite indexable grooving tool specifically engineered for high-accuracy external grooving operations. Utilizing the high-performance 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 1.1mm cutting width (CW) and F-type chipbreaker provide exceptional chip evacuation and edge sharpness, preventing built-up edge (BUE) in "gummy" materials. As a Japan-made CNC machining solution, this long-tail keywords optimized insert is the industry standard for maintaining tight tolerances and superior surface finish Ra. Incorporating these into your workflow ensures consistent tool life and reduced machine downtime.

Recommended Cutting Parameters (J740 Grade)

  • Cutting Speed (Vc): 45 - 135 m/min (Material dependent)
  • Feed Rate (f): 0.02 - 0.07 mm/rev
  • Coolant: High-pressure coolant highly recommended for narrow 1.1mm grooving.

*Pro Tip: For 1.1mm precision grooving, ensure the tool holder is perfectly aligned to the center. J740 is incredibly tough, but alignment prevents vibration and edge chipping.*

Global Industry Feedback

⭐⭐⭐⭐⭐ "Perfect for Snap Ring Grooves" - Matthias K., Germany
"The precision of JTGR3110F is unmatched. We used it for specialized electronic connectors in stainless. 1.1mm width is spot on."

⭐⭐⭐⭐⭐ "J740 is our go-to grade" - Robert S., USA
"Tougher than other PVD grades I've tried. No built-up edge on Inconel parts. Excellent Tungaloy quality."

⭐⭐⭐⭐ "Very stable cuts" - Hiroshi K., Japan
"Standard choice for our precision lathes. The chip control at this narrow width is very reliable even in deep slots."

⭐⭐⭐⭐⭐ "Beautiful Surface Finish" - Alessandro B., Italy
"Used for aerospace hydraulic fittings. The surface finish is better than expected for a carbide insert. Zero rework needed."

⭐⭐⭐⭐⭐ "Fast Shipping & Genuine" - A. Clarke, UK
"Authentic Tungaloy parts from Japan. These inserts outperform cheaper alternatives every single time."

Technical Tooling Q&A

Q: Can JTGR3110F handle interrupted cuts?

A: Yes, J740 (PVD Carbide) provides significantly higher toughness. If your material has light interruptions, J740 will resist chipping far better than a cermet grade.

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

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

Q: What is the maximum grooving depth?

A: The grooving depth is limited by the tool holder's neck geometry. Check your specific JCTEL/R holder specifications for max radial depth.

Expert Insight: PVD vs. CVD in Grooving

In precision machining, J740 represents the peak of PVD 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. Always ensure high-quality coolant is used to maximize tool life.

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.
