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.

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

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.
