Tungaloy RCMT0502MO-61 T9115 Insert

Round Positive Turning | 61 Finishing Breaker | Premium T9115 CVD Grade

What is the best round insert for high-speed steel turning?

The Tungaloy RCMT0502MO-61 T9115 is a high-performance round carbide turning insert engineered for efficiency in steel machining. Featuring the advanced T9115 CVD coated grade, this tool is designed to withstand high temperatures and provide exceptional wear resistance during continuous cutting. The 61 chipbreaker offers superior chip control for light-duty finishing to semi-finishing, preventing chip wrapping and improving surface quality. This Japan-made CNC turning insert is a versatile solution for profiling and high-feed machining where edge strength is paramount.

T9115 Premium Grade

Advanced CVD coating provides a thick Al2O3 layer for extreme heat resistance and long tool life in high-speed steel turning.

Excellent Chip Control

The 61 breaker is specifically designed for finishing, ensuring stable chip evacuation even at small depths of cut.

Robust Round Geometry

RCMT inserts offer the highest cutting edge strength, ideal for profiling and machining parts with varying diameters.

8. FAQ - Common Technical Questions

Q: Is T9115 suitable for interrupted cuts?

A: T9115 is optimized for continuous cutting at high speeds. For heavily interrupted cuts, a grade like T9125 might be more suitable due to higher toughness.

Q: Can I use this for stainless steel?

A: T9115 is specifically designed for general steel (ISO P). For stainless steel, we recommend Tungaloy grades like AH630 or AH645.

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

A: It is designed for 'Light Cut' finishing. It minimizes cutting resistance, which helps in maintaining tight tolerances on slender workpieces.

Expert Insight: Premium T9115 CVD Grade

In high-speed CNC turning, the T9115 grade stands out with its thick Al2O3 layer which acts as a thermal barrier. This prevents crater wear and plastic deformation at the cutting edge, allowing the RCMT0502 to maintain precision and stability over long production runs on steel.

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.

When will my order ship and arrive?
