Tungaloy GE Series Grooving Inserts

Precision Grooving & Parting | GH730, T9125, T9225 Grades | Made in Japan

Which Tungaloy GE insert grade is best for stainless steel grooving?

The Tungaloy GE Series represents a versatile solution for high-precision grooving and parting-off operations. Whether you are using the GE20, GE30, GE40, or GE50 sizes, these indexable grooving tools provide exceptional edge stability and chip control. Available in the GH730 PVD coated grade for stainless steel and heat-resistant alloys, or the T9125 and T9225 CVD grades for high-speed steel machining, this series is engineered for the modern CNC machining environment. By utilizing these long-tail keywords optimized inserts, you ensure high-speed performance, excellent surface Ra, and significantly extended tool life in both external and internal grooving cycles.

Available Models: Metric & Imperial Equivalence

Model Name Insert Width (Metric) Imperial Equivalent Best Grade For
GE20 GH730 2.0 mm 0.079" Stainless/Universal
GE30 GH730 / T9125 3.0 mm 0.118" Stainless / Steel
GE40 GH730 / T9125 4.0 mm 0.157" Stainless / Steel
GE50 GH730 / T9225 5.0 mm 0.197" General Steel Finishing

Recommended Cutting Parameters

  • GH730 (PVD): Vc: 60 - 150 m/min | Feed: 0.05 - 0.15 mm/rev (Best for Stainless)
  • T9125/T9225 (CVD): Vc: 120 - 250 m/min | Feed: 0.08 - 0.20 mm/rev (Best for Carbon Steel)

*Pro Tip: Ensure stable clamping. For deep grooves, use peck-cycle grooving to prevent chip packing and ensure cool-tip performance.*

Global Machinist Reviews

⭐⭐⭐⭐⭐ "GH730 is King for 316L" - Dieter S., Germany
"The GE30 GH730 works beautifully on stainless. The chip control is predictable, and I get a great finish every time."

⭐⭐⭐⭐⭐ "High Speed Steel Grooving" - James W., USA
"T9125 grade allows us to push the speed on 1018 steel. Very long tool life compared to the cheaper alternatives."

⭐⭐⭐⭐ "Very Sharp Edge" - Hiroki L., Japan
"Japan made quality as expected. The precision on the GE20 width is spot on for my tight tolerance parts."

⭐⭐⭐⭐⭐ "Great for Parting Off" - Luca P., Italy
"We use the GE40 for parting 40mm bars. No vibration and clean cuts. Very reliable series."

⭐⭐⭐⭐⭐ "Predictable Wear" - Sarah J., Australia
"Consistent results. T9225 is very tough and handles light interruptions without chipping."

Tooling Expert Q&A

Q: Can I use the same holder for GE20 and GE50?

A: No. Each insert size (20, 30, 40, 50) usually corresponds to a specific pocket size in the tool holder. Always match your insert size to the holder designation (e.g., CGER/L holders).

Q: When should I choose GH730 over T9125?

A: Choose GH730 (PVD) for stainless steel and alloys where toughness and resistance to built-up edge are needed. Choose T9125 (CVD) for high-speed grooving in carbon and alloy steels.

Q: Does the GE series support internal grooving?

A: Yes, with the appropriate internal grooving bar, the GE series performs exceptionally well for ID grooving operations.

Expert Comparison: PVD vs. CVD in Grooving

In precision machining, grade selection is vital. GH730 (PVD) offers a thinner, sharper coating for low-speed/high-toughness apps. T9125/T9225 (CVD) offers a thicker, heat-resistant layer for high-volume steel production. Protect your indexable grooving tool by matching the grade to your workpiece material.

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.
