TaeguTec CCMT120404PC TT9225
The Universal Steel Specialist: Advanced CVD Multi-Layer Coating
Product Overview
"Which insert grade offers the best balance of tool life and surface finish when turning alloy steels at high spindle speeds?"
The TaeguTec CCMT120404PC TT9225 is a high-performance 80° rhombic turning insert specifically engineered for ISO P (Steel) and ISO M (Stainless Steel). Utilizing a thick, multi-layer CVD (Chemical Vapor Deposition) coating, the TT9225 grade provides a formidable thermal barrier against crater wear and plastic deformation. The PC (Precision Cutting) chipbreaker features a sharp rake angle and positive geometry, which significantly reduces radial cutting forces—making it the ideal choice for precision finishing and small-diameter boring where vibration control is paramount.
Key Features
Thick Al2O3 layer ensures superior heat resistance, allowing for higher cutting speeds in continuous machining.
Optimized for finishing applications; provides excellent chip breaking even at light depths of cut (Ap).
Reduces friction and cutting temperatures, preventing built-up edge (BUE) in gummy materials like stainless steel.

Global Verified Reviews
"Excellent Finish on 4140"
Replaced my previous brand with TT9225. Spindle speed is up by 20% and the surface is mirror-like. Highly recommend the PC chipbreaker for boring.
— Hans M., Germany"Consistent Life"
Running these on a long production run of 304 SS. Tool wear is very predictable, which is exactly what we need for lights-out machining.
— Robert T., USA"Best for High Speed"
CVD coating handles the heat perfectly. Even when the chips are blue, the insert edge stays sharp. Good price point too.
— Tanaka K., JapanFrequently Asked Questions
Q: Is TT9225 suitable for heavy interrupted cuts?
A: While TT9225 has decent toughness, PVD grades like TT9080 are generally preferred for heavy interruptions. TT9225 excels in continuous to light interrupted turning.
Q: What is the benefit of the PC chipbreaker over standard ones?
A: The PC geometry is designed for precision cutting; it reduces radial pressure which prevents chatter in boring bars and thin workpieces.

Technical FAQ & Buying Guide
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.
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.
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.
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.
