Tungaloy WGE50 GH730 Grooving Insert

Heavy-Duty 5mm Grooving | High-Toughness GH730 PVD Grade

"Which 5mm insert is best for heavy-duty grooving in difficult-to-cut stainless alloys?"

The Tungaloy WGE50 GH730 is a premium 5.0mm width double-ended insert engineered for maximum stability in external grooving and parting-off operations. Designed to handle high-load machining, the GH730 PVD coated carbide grade provides an exceptional balance of wear resistance and fracture toughness. This makes it the go-to choice for Stainless Steel and Heat-Resistant Superalloys. Its specialized chipbreaker geometry ensures that even under heavy depths of cut, chips are effectively curled and broken, preventing surface damage and ensuring the structural integrity of the tool during intensive production cycles.

GH730 PVD Durability

Advanced multi-layer PVD coating designed to combat notch wear and chemical oxidation. Ideal for materials with high thermal resistance.

Heavy-Duty 5mm Edge

Reinforced 5mm width providing high rigidity. Perfect for large diameter parting-off and deep radial grooving without vibration.

Repeatable Indexing

Precision-ground seating ensures that when flipping to the second edge, the centerline height remains perfectly accurate.

Customer Reviews

⭐⭐⭐⭐⭐ "Workhorse for Stainless" - James H., USA
"We use the WGE50 GH730 for our heavy hydraulic shaft parting. It is a workhorse. The GH730 grade handles the heat build-up in 316 stainless better than any other insert."

⭐⭐⭐⭐⭐ "Stable at 5mm" - Dieter W., Germany
"Excellent stability in deep grooves. No chatter at all. BEYOND provided technical parameters that improved our cycle time by 15%."

⭐⭐⭐⭐ "Professional and Fast" - Takumi S., Japan
"Ordering from Beyond is easy. The parts are always original and the shipping is faster than many local suppliers."

Technical FAQ

Q: Can I use WGE50 for plunge-turning?

A: Yes, but ensure your feed rate is adjusted. The GH730 grade is tough enough for light turning, but primarily optimized for radial grooving.

Q: What coolant setup is best for GH730?

A: High-pressure through-tool coolant is ideal to prevent chip re-cutting and to maximize the lifespan of the PVD coating in stainless.

Industrial Tip: Monitoring Edge Wear

When machining high-temp alloys with **GH730**, watch for notch wear at the DOC line. If noticed, slightly vary your depth of cut between passes to distribute the wear. **BEYOND CNC** - Your Industrial Tooling Expert.

Technical FAQ & Buying Guide

Are your carbide inserts interchangeable with major brands like Sandvik, Iscar, or Kennametal?

Absolutely. Our CNC carbide inserts (including CNMG, WNMG, DNMG, and APMT series) are manufactured strictly adhering to international ISO/ANSI specifications. A CNMG 120408 from OYYU BEYOND will flawlessly fit any standard turning tool holder or indexable tool from major global brands like Sandvik Coromant, Kennametal, Iscar, Walter, or SECO, providing a highly cost-effective premium alternative without sacrificing tolerance or tool life.

How do I choose the correct insert grade and chipbreaker for machining Stainless Steel (M) vs. Carbon Steel (P)?

We offer optimized CVD and PVD multi-layer coatings for different ISO material groups:

  • For Carbon/Alloy Steel (ISO P): Choose our thick multi-layer CVD coated grades (e.g., Al2O3 + TiN). They provide exceptional crater wear resistance and thermal barriers during high-speed dry or wet roughing.
  • For Stainless Steel (ISO M): Choose our nano-structured PVD coated grades with sharp, positive chipbreakers (like -TM or -MA). This combination prevents work hardening and effectively controls sticky chips.
What are the recommended cutting speed (Vc) and feed rate (f) parameters to maximize tool life?

The optimal cutting parameters vary depending on the workpiece hardness and operation type:

  • For General Steel Turnings: Recommended cutting speed ($V_c$) ranges from 150 to 280 m/min, with a feed rate ($f$) of 0.15 to 0.45 mm/rev.
  • For Stainless Steel Finishing: Recommended cutting speed ($V_c$) is 120 to 200 m/min, with a feed rate ($f$) of 0.10 to 0.25 mm/rev.Always adjust parameters based on early wear patterns: increase $V_c$ if built-up edge occurs, or reduce $V_c$ if severe flank wear is observed.
Do you offer bulk discounts or wholesale pricing for machine shops and distributors?

Yes, we support machine shops, distributors, and global buyers with tiered wholesale pricing and competitive volume discounts. We also provide OEM custom manufacturing solutions for tool holders and carbide inserts based on your technical drawings. Contact our team to request a quick B2B quotation.

What is your international shipping policy and typical lead time for orders?

We provide secure worldwide express shipping (via DHL, FedEx, and UPS) with specialized, vibration-proof industrial packaging to ensure tools arrive in perfect condition. In-stock items are dispatched within 24-48 hours, while custom or bulk orders typically have a stable lead time of 15-25 days.

How do you guarantee the quality and tolerance precision of your CNC tools?

All our cutting tools and tool holders are manufactured strictly in accordance with ISO 9001 and international industrial standards. Every batch undergoes 100% rigorous quality control testing using high-precision optical measuring equipment to ensure reliable tool life and stable performance in continuous mass production.
