Tungaloy JTGR3075F J740 Grooving Insert

High-Precision 0.75mm External Grooving | PVD J740 Grade | Made in Japan

What is the most durable insert for 0.75mm precision grooving?

The Tungaloy JTGR3075F J740 is an elite-level indexable grooving tool specifically engineered for narrow, high-accuracy external grooving. Utilizing the renowned J740 PVD coated carbide grade, this insert provides exceptional toughness and resistance to Built-Up Edge (BUE), making it the primary choice for machining stainless steel, heat-resistant alloys, and carbon steels. The 0.75mm cutting width is ideal for micro-grooving and fine component parting where dimensional accuracy is critical. As a premium CNC machining component made in Japan, this long-tail keywords optimized insert ensures maximum tool life and repeatability in the most demanding production cycles.

Recommended Cutting Parameters (J740 Grade)

  • Cutting Speed (Vc): 40 - 140 m/min (Highly dependent on material hardness)
  • Feed Rate (f): 0.02 - 0.06 mm/rev (For micro-grooving stabilization)
  • Coolant: High-pressure coolant is highly recommended to flush chips from narrow 0.75mm slots.

*Pro Tip: For precision parting or grooving on small diameters, always check your tool center height to prevent rubbing and premature wear.*

Global Industry Feedback

Technical Tooling Q&A

Q: Can JTGR3075F handle stainless steel 316?

A: Yes, the J740 PVD grade is specifically optimized for stainless steel. It prevents the built-up edge and withstands the heat generated in difficult-to-cut alloys.

Q: Which tool holder is compatible with this insert?

A: This insert fits Tungaloy's J-Series external grooving holders (JCTEL/R). Ensure your holder matches the 3xxx seat size series.

Q: Is there a Left-Hand version available?

A: This specific model is Right-Hand (R). For Left-Hand operations, you would require the JTGL series with a matching JCTEL holder.

Expert Insight: J740 PVD Versatility

In precision machining, J740 represents a breakthrough in PVD coating technology for CNC grooving. While CVD grades excel in continuous high-speed turning, J740 provides the edge toughness required for the repetitive shock of grooving and parting cycles. 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.
