Tungaloy RPMT & RPMW AH120 Series

High-Stability Round Milling | PVD Coated AH120 | Universal Steel Grade

What are the best round milling inserts for general steel and stainless?

The Tungaloy RPMT/RPMW series in AH120 grade represents the pinnacle of versatility in CNC round milling. Engineered for high-feed profiling, face milling, and ramp-down operations, these inserts utilize a specialized PVD coating that excels in both carbon steel and stainless steel applications. Whether you are using the RPMT08T2MO-M01 for smaller components or the RPMT1204MO-M01 for heavy-duty metal removal, the AH120 grade provides an exceptional balance of wear resistance and toughness. The round geometry ensures the strongest possible cutting edge, making these inserts ideal for 3D contouring and roughing in rigid setups.

Multi-Purpose AH120 Grade

A versatile PVD coated grade that offers high resistance to oxidation and chipping. Ideal for mixed production involving various steel types.

High-Feed Round Design

Round inserts provide superior edge strength and allow for larger feed rates compared to traditional square or diamond inserts.

M01 Chipbreaker Advantage

Designed for general-purpose milling, the M01 breaker optimizes chip flow and reduces heat buildup during continuous cutting.

3. Technical Specifications: Metric vs. Imperial

ISO Model Metric Diameter (IC) Imperial Equiv. Thickness
RPMT08T2MO 8.0 mm 5/16" approx. 2.78 mm
RPMW1003MO 10.0 mm 3/8" approx. 3.18 mm
RPMT10T3MO 10.0 mm 3/8" approx. 3.97 mm
RPMT1204MO 12.0 mm 1/2" approx. 4.76 mm

Recommended Parameters (AH120 Grade)

  • Cutting Speed (Vc): 80 - 180 m/min (Standard Carbon Steels)
  • Feed per Tooth (fz): 0.10 - 0.40 mm/t (Depending on Diameter)
  • Depth of Cut (ap): 0.5 - 3.0 mm (Size Dependent)

*Pro Tip: For stainless steel, reduce Vc by 20% and maintain a constant feed rate to prevent work hardening.*

4. Product Applications

  • 3D Profiling and Die & Mold machining.
  • Roughing and semi-finishing of Carbon & Alloy steels.
  • Stable machining of Stainless Steels (ISO M).
  • Helical interpolation and ramp milling.

5. Equipment Compatibility

Optimized for Tungaloy FixRMill (SRDCN/SRGCR style) cutters and other standard round milling tool holders. Fits CNC Machining Centers and Lathes with milling capability.

Customer Reviews

⭐⭐⭐⭐⭐ "Workhorse for Profiling" - D. Miller, UK
"The RPMT1204 in AH120 is our standard roughing insert. It handles scale and rough surfaces on steel plate without chipping."

⭐⭐⭐⭐⭐ "Great Stability" - K. Schneider, Germany
"Using the 08T2 for small mold cavities. Very reliable tool life and excellent surface finish for a roughing insert."

⭐⭐⭐⭐ "Universal Grade" - T. Sato, Japan
"AH120 grade is very convenient. We switch from P20 tool steel to 304 stainless without changing the insert."

⭐⭐⭐⭐⭐ "Best Price Performance" - J. Costa, Italy
"Top quality from Tungaloy. Fast delivery and the performance in alloy steel is outstanding."

⭐⭐⭐⭐⭐ "Solid Performance" - R. Tan, Singapore
"Original products. The round shape really allows for high-speed roughing that would kill a diamond insert."

8. FAQ - Professional Machining

Q: What is the difference between RPMT and RPMW?

A: RPMT features a chipbreaker (like M01) for better chip control, while RPMW is typically a flat-top design for specific applications.

Q: Can AH120 be used for High-Temp Alloys?

A: It can handle some Heat Resistant Super Alloys (HRSA), but we recommend Tungaloy AH3135 for dedicated HRSA tasks.

Q: Why choose round inserts for milling?

A: Round inserts have the strongest cutting edge geometry and provide varying entry angles, which helps reduce radial forces and vibration.

Expert Insight: The AH120 PVD Advantage

In CNC milling, thermal cracking is the primary enemy. The AH120 grade uses a specialized PVD coating that acts as a thermal barrier while maintaining an incredibly sharp edge. This prevents the heat from reaching the carbide substrate, ensuring the RPMT series provides long, predictable tool life in carbon and stainless steels.

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.
