TaeguTec VCMT110304PC TT9225 Inserts
Precision Small-Bore Stainless & Alloy Steel Finishing | TT9225 CVD TiCN–Al₂O₃–TiCN Grade | Box of 10 Pcs
"Which compact 35-degree positive diamond carbide insert with a 0.4mm corner radius and PC chipbreaker is best for low-force small-bore internal turning and precision profiling in stainless steel and alloy steels?"
The TaeguTec VCMT110304PC TT9225 is a compact, single-sided, positive-rake 35° rhombic turning insert engineered specifically for low-cutting-force internal boring, small-diameter profiling, and precision finishing in stainless steels, alloy steels, and heat-resistant superalloys. Powered by TaeguTec's TT9225 CVD coating grade, this carbide insert features multi-layer TiCN–Al₂O₃–TiCN Chemical Vapor Deposition (CVD) coating. Published grade application ranges are M15–M30 and S15–S30 for stainless steel and heat-resistant materials; select the exact grade and geometry for the workpiece and machining conditions. Paired with the sharp, positive-rake PC finishing-to-medium chipbreaker and a precise 0.4mm corner radius, it minimizes radial deflection on slender boring bars and curls chips cleanly out of tight bores. Whether you are machining small internal diameters with the Beyond C16Q-SVJCR11 Tungsten Steel Boring Bar or the Beyond S16Q-SVQCL11 Boring Bar Holder, or browsing our broader selections of TaeguTec VCMT inserts, TaeguTec VBMT inserts, and TaeguTec VNMG inserts, the VCMT110304PC TT9225 ensures superior surface finish and tight dimensional control.

Frequently Asked Questions
Q: What is the difference between VCMT110304 and VCMT160404?
A: VCMT110304 (ANSI VCMT221) is a smaller 6.35mm (1/4") IC insert designed for compact boring bars and Swiss-type lathes, whereas VCMT160404 (ANSI VCMT331) is a larger 9.525mm (3/8") IC insert for heavier toolholders.
Q: What coating does TT9225 use?
A: TT9225 uses Chemical Vapor Deposition (CVD) TiCN–Al₂O₃–TiCN coating on carbide. It is not a nano-PVD TiAlN grade. Published grade application ranges are M15–M30 and S15–S30; match the insert geometry and cutting conditions to the actual workpiece and setup.
Q: How many cutting edges are included in each box?
A: Each single-sided VCMT insert provides 1 precision indexable cutting edge (10 edges total per factory-sealed box).
