Tungaloy RCMT0803MO-61 TH10 Insert

Non-Ferrous Precision | 61 Finishing Breaker | Sub-Micron TH10 Grade

Which round insert provides a mirror finish on aluminum parts?

The Tungaloy RCMT0803MO-61 TH10 is a premier uncoated carbide turning insert designed specifically for superior performance in non-ferrous materials. Utilizing the TH10 sub-micron carbide grade, it offers exceptional hardness and a razor-sharp edge that effectively prevents "built-up edge" (BUE) when machining sticky materials like aluminum or copper alloys. The 61 chipbreaker features a high positive rake angle for effortless cutting, ensuring high-speed finishing with incredible surface integrity. Made in Japan, this CNC turning insert is the professional choice for complex profiling and 3D contouring of high-value non-ferrous components.

Sub-Micron TH10 Grade

An uncoated grade with high wear resistance and toughness. Perfect for high-velocity machining of aluminum, brass, and plastics.

Mirror Surface Geometry

The polished top face reduces friction, ensuring smooth chip flow and preventing material adhesion on the cutting edge.

High-Feed Profiling

The RCMT round shape provides maximum edge strength, allowing for aggressive profiling and 3D contouring without risk of chipping.

"Fast shipping from beyond. These RCMT0803 inserts are essential for our precision aluminum shop."

8. FAQ - Common Technical Questions

Q: Can I use this for Stainless Steel?

A: No. TH10 is an uncoated grade for non-ferrous metals. For Stainless Steel, please use Tungaloy AH630 or AH645 grades.

Q: What is the main advantage of the 61 chipbreaker?

A: It is designed for light-duty finishing, offering a very sharp cutting action that produces superior surface finishes on soft metals.

Q: Does it fit standard ISO holders?

A: Yes, it is a standard ISO RCMT0803 insert and fits all compatible SRDCN/SRGCR tool holders.

Expert Insight: The TH10 Non-Ferrous Advantage

In high-speed aluminum turning, heat is the enemy of the surface finish. The TH10 grade's sub-micron grain structure allows for an incredibly sharp edge that 'slices' the material rather than tearing it. This prevents the sticky aluminum from welding to the tip, ensuring that the RCMT0803 maintains its mirror-finish capability throughout the batch.

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.
