TaeguTec TPGT 110304L-C CT3000

Elite Uncoated Cermet for High-Precision Mirror Finishing

Product Overview

"Which positive insert is best for achieving high-gloss surface finishes on steel components using a left-hand boring bar?"

The TaeguTec TPGT 110304L-C CT3000 is a high-performance turning insert designed for the final finishing stage. Utilizing the CT3000 uncoated Cermet grade, it provides exceptional chemical stability and oxidation resistance. This prevents the "welding" of work material to the edge, ensuring a clean cut and a superior mirror finish on ISO P (Steel). The -C chipbreaker is a sharp, positive geometry that reduces cutting forces and vibration, making it perfect for small diameters and high-speed precision boring.

Key Core Advantages

Exceptional Ra Surface Integrity

Cermet’s low affinity for steel eliminates built-up edge, allowing for Ra values that often bypass the need for secondary grinding.

Precision Boring Geometry

The positive 11° clearance angle (T) combined with the sharp -C chipbreaker minimizes deflection in small-hole boring.

High-Speed Performance

Uncoated CT3000 is optimized for high Vc (Cutting Speeds), maximizing productivity while maintaining dimensional accuracy.

Why Machinists Choose CT3000?

When "good enough" isn't an option for your surface finish, CT3000 Cermet delivers. The TPGT 110304L-C geometry provides the sharpness required for light depths of cut without creating tool pressure that causes chatter. The -C chipbreaker ensures that the small, thin chips produced during finishing passes are effectively broken, preventing surface scratching. This is the ultimate tool for high-precision steel turning and boring where aesthetic and dimensional consistency are the priority.

Frequently Asked Questions

Q: Can I use Cermet for heavy roughing?
A: No. Cermet is optimized for finishing. For roughing, we recommend TaeguTec TT9225 or TT8125 carbide grades.
Q: Is coolant necessary with CT3000?
A: Cermet can run dry at high speeds, which often prevents thermal shock. If using coolant, ensure it is high-pressure and consistent.
Q: What is the optimal depth of cut (Ap) for this insert?
A: To get the best results from the -C chipbreaker, aim for an Ap between 0.1mm and 1.2mm.

Machinist's Tip: When using CT3000, keep your cutting speed high. Cermet thrives on heat—low speeds can cause chipping.

Technical FAQ & Buying Guide

Are your carbide inserts interchangeable with major brands like Sandvik, Iscar, or Kennametal?

Absolutely. Our CNC carbide inserts (including CNMG, WNMG, DNMG, and APMT series) are manufactured strictly adhering to international ISO/ANSI specifications. A CNMG 120408 from OYYU BEYOND will flawlessly fit any standard turning tool holder or indexable tool from major global brands like Sandvik Coromant, Kennametal, Iscar, Walter, or SECO, providing a highly cost-effective premium alternative without sacrificing tolerance or tool life.

How do I choose the correct insert grade and chipbreaker for machining Stainless Steel (M) vs. Carbon Steel (P)?

We offer optimized CVD and PVD multi-layer coatings for different ISO material groups:

  • For Carbon/Alloy Steel (ISO P): Choose our thick multi-layer CVD coated grades (e.g., Al2O3 + TiN). They provide exceptional crater wear resistance and thermal barriers during high-speed dry or wet roughing.
  • For Stainless Steel (ISO M): Choose our nano-structured PVD coated grades with sharp, positive chipbreakers (like -TM or -MA). This combination prevents work hardening and effectively controls sticky chips.
What are the recommended cutting speed (Vc) and feed rate (f) parameters to maximize tool life?

The optimal cutting parameters vary depending on the workpiece hardness and operation type:

  • For General Steel Turnings: Recommended cutting speed ($V_c$) ranges from 150 to 280 m/min, with a feed rate ($f$) of 0.15 to 0.45 mm/rev.
  • For Stainless Steel Finishing: Recommended cutting speed ($V_c$) is 120 to 200 m/min, with a feed rate ($f$) of 0.10 to 0.25 mm/rev.Always adjust parameters based on early wear patterns: increase $V_c$ if built-up edge occurs, or reduce $V_c$ if severe flank wear is observed.
Do you offer bulk discounts or wholesale pricing for machine shops and distributors?

Yes, we support machine shops, distributors, and global buyers with tiered wholesale pricing and competitive volume discounts. We also provide OEM custom manufacturing solutions for tool holders and carbide inserts based on your technical drawings. Contact our team to request a quick B2B quotation.

What is your international shipping policy and typical lead time for orders?

We provide secure worldwide express shipping (via DHL, FedEx, and UPS) with specialized, vibration-proof industrial packaging to ensure tools arrive in perfect condition. In-stock items are dispatched within 24-48 hours, while custom or bulk orders typically have a stable lead time of 15-25 days.
