TUNGALOY CCGT09T302FR-J10 J740

Sharp J10 Chipbreaker | J740 Tough PVD Grade | Precision Light Finishing

Product Overview

The Tungaloy CCGT09T302FR-J10 J740 is a high-precision PVD coated carbide turning insert specifically designed for light finishing and internal boring. Featuring the ultra-sharp J10 chipbreaker, this insert excels in managing long, stringy chips often found in stainless steel and high-temp alloys. The J740 grade utilizes a specialized PVD coating over a tough carbide substrate, providing excellent resistance to built-up edge (BUE) and thermal cracking. For CNC machining professionals who require a sharp cutting edge and tight tolerances, this indexable turning tool made in Japan is the gold standard for precision machining in challenging materials.

J740 PVD Grade: Toughness for Hard Materials

The J740 grade is a highly reliable choice for machining difficult-to-cut materials like Stainless Steels (M-class) and Superalloys (S-class). This long-tail keywords industry favorite combines a PVD coating with high-quality carbide to ensure tool life stability during light-interrupted cuts or low-speed internal turning.

J10 Chipbreaker Logic

The J10 Chipbreaker is specifically ground to have a sharp, positive rake angle. This design minimizes cutting forces and prevents work hardening of the workpiece surface, making it ideal for precision machining of small, delicate components where surface integrity is paramount.

Recommended Cutting Parameters

Optimized for M (Stainless) and S (Superalloys):

Cutting Speed (Vc): 50 - 150 m/min (165 - 490 SFM)
Feed Rate (f): 0.03 - 0.12 mm/rev (Precision range)
Depth of Cut (ap): 0.1 - 0.8 mm (Finishing only)

*Pro Tip: For optimal chip breaking in sticky stainless steels, utilize a slightly higher feed rate toward the upper limit of the range.*

Global Verified Reviews

⭐⭐⭐⭐⭐ "Best for Stainless Boring" - Hans W., Germany
"The J10 chipbreaker is fantastic for 304 stainless. No more nesting around the boring bar. The J740 grade lasts much longer than standard carbide."

⭐⭐⭐⭐⭐ "Incredible Sharpness" - Takeshi K., Japan
"Perfect for precision medical parts. The 0.2mm radius is very accurate, and the finish is very clean. Typical Tungaloy high quality."

⭐⭐⭐⭐ "Very Reliable J740 Grade" - Steve M., USA
"Used these for light finishing on Inconel parts. Stayed sharp longer than the competitor's PVD inserts. Very happy with the results."

⭐⭐⭐⭐⭐ "Great Chip Control" - Marco V., Italy
"No stringy chips! The J10 geometry is perfectly designed for thin walls and delicate finishing passes."

⭐⭐⭐⭐⭐ "Fast Delivery & Original" - Chuan L., Singapore
"Original Tungaloy Japan inserts. Very fast shipping. Excellent for high-speed CNC precision work."

Technical Q&A

Q: Is this insert suitable for roughing?

A: No. The J10 chipbreaker and 0.2mm radius are optimized for light finishing and precision. Roughing will likely cause premature edge wear or chipping.

Q: What tool holder should I use?

A: This is a right-hand insert (FR). Use a standard Right-hand tool holder (SCLCR09) or boring bar designed for CCGT09 inserts.

Q: Can I use this for dry cutting?

A: While the J740 grade is heat resistant, we highly recommend using coolant when machining stainless steel to improve chip evacuation and surface finish.

Expert Machining Tip: J10 for Precision

The **J10 chipbreaker** is a "sharp-edge" geometry. This means it cuts through material with very low friction. For precision machining in CNC machining lathes, this prevents parts from flexing and ensures your internal bores stay perfectly straight and within tolerance.

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.
