Tungaloy WGE20 / WGE20R GH730 Grooving Inserts

High-Stability PVD Carbide | Precision Grooving & Parting

"Which insert is most reliable for precision grooving in difficult-to-cut materials like stainless steel?"

The Tungaloy WGE20 and WGE20R in GH730 grade are high-precision grooving inserts designed for exceptional stability. Featuring a specialized PVD coating on a micro-grain carbide substrate, the GH730 grade provides superior resistance to notch wear and built-up edge, making it the industry standard for machining Stainless Steel and Heat-Resistant Alloys. Whether you require the neutral WGE20 or the right-handed WGE20R, these inserts feature a robust geometry that ensures excellent chip evacuation even in narrow 2mm grooves, maintaining workpiece integrity and tool longevity.

GH730 Wear Resistance

The multi-layer PVD coating is optimized for toughness. It prevents fracture during interrupted grooving and provides a smooth surface for chip flow.

2mm Precision Edge

Ground with high accuracy to ensure precise groove widths and sharp corners, vital for hydraulic and automotive components.

Optimized Evacuation

The top-face geometry forces chips to curl and break quickly, preventing "chip nesting" which can lead to tool breakage.

Customer Reviews

⭐⭐⭐⭐⭐ "Best for 316 Stainless" - Robert K., USA
"We've struggled with grooving 316 stainless for years. The GH730 grade from Tungaloy has significantly improved our tool life. No more edge chipping."

⭐⭐⭐⭐⭐ "Perfect Parting" - Stefan M., Germany
"The WGE20 neutral insert is very stable. Even with higher feed rates, the finish remains consistent. High-quality PVD coating."

⭐⭐⭐⭐ "Fast Shipping" - Hiroshi T., Japan
"Received genuine Tungaloy inserts quickly. The performance in Inconel was much better than our previous supplier."

Technical FAQ

Q: What is the difference between WGE20 and WGE20R?

A: WGE20 is a neutral insert, whereas WGE20R is right-handed. Choice depends on your holder and the direction of your lathe spindle.

Q: Can I use GH730 for steel?

A: Yes, GH730 is a versatile grade. While optimized for stainless and alloys, it performs excellently in alloy steels where toughness is required.

Pro Machining Tip: Coolant is Mandatory

When grooving stainless steel with **GH730**, ensure high-pressure coolant is directed at the cutting zone. This prevents thermal shock and keeps the PVD coating intact for maximum life. **BEYOND CNC** - Your Precision Partner.

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.
