Tungaloy WGE40 / WGE40R GH730 Grooving Inserts

High-Load 4mm Grooving | Superior Toughness GH730 PVD Grade

"Which 4mm insert is most reliable for high-stability grooving in tough alloy steels?"

The Tungaloy WGE40 and WGE40R in GH730 grade represent the industrial standard for medium-width external grooving and parting-off. Designed for heavy-duty applications, the 4.0mm width geometry combined with the GH730 PVD coated carbide provides a robust solution for machining Stainless Steel, Carbon Steel, and Heat-Resistant Superalloys. The GH730 grade utilizes a high-toughness micro-grain substrate that absorbs mechanical shock during interrupted cuts, while the specialized PVD coating resists thermal cracking and chemical wear. Whether you choose the neutral WGE40 or the right-handed WGE40R, you are guaranteed superior chip control and dimensional accuracy in every cycle.

GH730 Extreme Durability

An advanced PVD coating optimized for toughness. It effectively stops crack propagation and provides an ultra-smooth surface to prevent chip welding.

Heavy-Duty Chipbreaker

The geometry is reinforced for the 4mm width, enabling efficient chip curling and breaking even at high feed rates in ductile materials like 304/316 Stainless.

Rigid Indexing

The double-ended "W" design ensures highly repeatable center-line heights and rigid clamping, reducing vibration in deep grooves.

Verified Industry Feedback

⭐⭐⭐⭐⭐ "Excellent in 4140 Steel" - Mike R., USA
"The WGE40 R in GH730 grade is my go-to for parting 4140 pre-hardened steel. The tool life is double what we got from previous European brands."

⭐⭐⭐⭐⭐ "Rock Solid 4mm Grooves" - Lars E., Germany
"Very rigid design. We get perfect flat bottoms on our grooves and zero chatter issues even at higher feeds."

⭐⭐⭐⭐ "Great Support" - Matteo V., Italy
"Beyond helped us choose the GH730 for our stainless project. It solved our chip control problems instantly. Highly recommended."

Technical FAQ

Q: Should I use WGE40 (Neutral) or WGE40R (Right Hand)?

A: This depends on your holder and lathe setup. If you are using a standard right-hand external holder, choose WGE40R for optimized clearance.

Q: Can I use this for longitudinal turning?

A: While primarily a grooving insert, the "W" series can handle light turning, but for heavy lateral loads, we recommend a dedicated turning-grooving insert.

Pro Machining Tip: Depth of Cut (ap)

When grooving with 4mm inserts like the **WGE40**, always ensure your feed rate is high enough to snap the chip. If the chip bird-nests, increase the feed by 10%—the **GH730** grade has the toughness to handle it. **BEYOND CNC** - Industrial Strength Precision.

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. A tracking number is sent by email after shipment.
