Tungaloy WGE30 / WGE30R GH730 Grooving Inserts

Professional 3mm Grooving | High-Toughness GH730 PVD Grade

"Which 3mm insert provides the best stability for grooving stainless steel and superalloys?"

The Tungaloy WGE30 and WGE30R in GH730 grade are high-precision external grooving and parting-off inserts. Engineered for the most demanding materials, the GH730 PVD coated carbide offers an ideal balance of hardness and fracture toughness. This grade is specifically designed to resist notch wear and built-up edge (BUE) when machining Stainless Steel and Heat-Resistant Superalloys. Whether using the neutral WGE30 or the right-handed WGE30R, the unique chipbreaker geometry ensures stable chip breaking across a wide range of feed rates, protecting your workpiece from chip-induced scratches and ensuring long, predictable tool life.

Multi-Layer PVD Coating

The GH730 grade features a micro-grain carbide substrate with advanced PVD coating, offering extreme thermal stability and resistance to plastic deformation.

Precision Width (3mm)

Ground to strict tolerances to ensure accurate groove dimensions and reliable performance in both automatic and manual CNC turning.

Double-Ended Economy

The "W" series design offers two cutting edges per insert, effectively doubling your productivity while reducing tool costs per component.

Global Industry Feedback

⭐⭐⭐⭐⭐ "Stable and Reliable" - David L., USA
"We use the WGE30 for all our 3mm grooves in stainless. GH730 holds up very well compared to other brands we've tested. No edge chipping."

⭐⭐⭐⭐⭐ "Great Price/Edge" - Klaus F., Germany
"Two edges per insert make these very economical. The parting cuts are clean and the accuracy of the 3mm width is spot on."

⭐⭐⭐⭐ "Professional Service" - Yuki M., Japan
"Always genuine parts. The technical support from Beyond helped us optimize our feed rates for tougher alloy grooving."

Technical FAQ

Q: Can WGE30R be used in a neutral holder?

A: No, WGE30R (Right Hand) must be paired with a corresponding Right-Hand holder to ensure proper clearance and chip flow.

Q: Is GH730 good for interrupted grooving?

A: Yes. GH730 is a PVD grade with a tough substrate specifically engineered to handle the shocks of light to medium interrupted cuts in stainless.

Industrial Tip: Chip Evacuation

When grooving deep bores or 3mm slots, use **constant surface speed (CSS)** and ensure clear chip evacuation. **GH730**'s coating prevents chip welding—keep your coolant pointed at the edge for best results. **BEYOND CNC** - Your Tooling Experts.

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.
