TaeguTec XCMT070304TC TT9030 Inserts
Precision Small-Diameter Turning & Drilling | Premium TT9030 PVD Grade | Box of 10 Pcs
"Which carbide insert is best for precision multi-function turning and small-diameter drilling in stainless steel?"
The TaeguTec XCMT070304TC TT9030 is a compact indexable insert specially engineered for high-precision operations combining internal boring, external turning, facing, and indexable drilling. Featuring TaeguTec's proprietary TT9030 PVD coating grade, this insert excels under high-friction and heat-intensive conditions by actively resisting Built-Up Edge (BUE) and notch wear. Its precision-ground TC chipbreaker geometry maintains low cutting forces and optimal chip curl across light-to-medium feed rates, preventing work hardening when machining 304/316 stainless steels, heat-resistant alloys, and carbon steel components.
Core Engineering Advantages
TT9030 Sub-Micron PVD Coating
Multi-layered TiAlN PVD coating provides extreme thermal resistance and surface lubricity for adhesive stainless steels.
TC Precision Chipbreaker
High positive rake design lowers spindle load, breaking long stringy chips cleanly during fine boring and drilling passes.
Compact 07-Size Versatility
Tailored for small bore diameters and compact lathe toolholders where space and stability are critical factors.

Frequently Asked Questions
Q: What is the main difference between XCMT07 and XCMT10 inserts?
A: The XCMT07 features a smaller 7mm edge length and 3.18mm thickness, making it ideal for smaller bore tools, compact indexable drills, and delicate Swiss-lathe operations compared to the larger 10mm version.
Q: Can TT9030 be run dry or with coolant?
A: While TT9030 PVD coating has high heat resistance for light dry turning, continuous flood coolant is highly recommended when machining stainless steel or using indexable drills to clear chips effectively.
Q: How many inserts are included per package?
A: Each factory pack contains 10 original TaeguTec XCMT070304TC TT9030 inserts in a sealed plastic case.
