Tungaloy CNMG160612 T9115 Turning Insert

High-Speed Steel Specialist | Robust 1.2mm Radius | Premium CVD Coating

How does the 1.2mm radius on T9115 improve stability in heavy steel turning?

The Tungaloy CNMG160612 T9115 is a heavy-duty CVD coated carbide turning insert engineered for high-efficiency machining in carbon and alloy steels. The T9115 grade features Tungaloy's "PremiumTec" surface technology, utilizing a thick, highly-textured Al2O3 layer that provides industry-leading heat resistance and crater wear protection. This indexable turning tool is specifically designed for CNC machining where high surface speeds and deep cuts are required. With its large 1.2mm corner radius, it offers exceptional edge strength and is capable of handling higher feed rates while maintaining a stable cutting edge. Made in Japan, this insert is a premier precision machining solution for workshops aiming to maximize tool life and productivity in demanding steel applications.

Is T9115 suitable for continuous high-speed steel turning?

The T9115 CVD Grade is the definitive choice for high-speed continuous cutting of steel. The thick coating acts as a massive thermal barrier, protecting the carbide substrate during long machining cycles. This long-tail keywords industry favorite is widely implemented in CNC machining large components where heat management is vital. The CNMG160612 geometry, with its robust 6.35mm thickness and 1.2mm radius, provides the mechanical strength needed for heavy roughing and semi-finishing. This combination drastically improves tool life and ensures that the insert can withstand the pressure of deep cuts and high feed rates in precision machining workflows.

Recommended Cutting Parameters for T9115

Optimized for P (Steel) and K (Cast Iron):

  • Cutting Speed (Vc): 150 - 450 m/min (depending on steel grade)
  • Feed Rate (f): 0.20 - 0.60 mm/rev
  • Depth of Cut (ap): 1.5 - 6.0 mm

*Pro Tip: Because of the 1.2mm radius, you can increase your feed rate while still maintaining a strong cutting edge.*

Feedback from Global Machining Experts

⭐⭐⭐⭐⭐ "Extreme durability on 4140 steel" - Markus J., Germany
"The 1.2mm radius on the CNMG1606 is a beast. We run high speeds on 4140 and the T9115 grade easily outlasts our previous tools."

⭐⭐⭐⭐⭐ "Stable edge for heavy cuts" - Kenji O., Japan
"Very predictable wear patterns. The thick insert body prevents vibration on our heavy-duty Mori Seiki. Tungaloy quality is 10/10."

⭐⭐⭐⭐ "Great for production" - David R., USA
"Cuts clean and fast. We use these for large diameter turning and the chip control is excellent even at high feed rates."

⭐⭐⭐⭐⭐ "Excellent thermal resistance" - Gianni B., Italy
"Running these at 350m/min and the edge stays intact. Best CVD grade for high-speed steel production."

⭐⭐⭐⭐⭐ "Authentic product, fast shipping" - Tan H., Singapore
"Genuine Tungaloy Japan inserts. Arrived in perfect condition. These 160612s are exactly what we needed for our heavy turning."

Technical Q&A

Q: Can I use T9115 for stainless steel turning?

A: T9115 is optimized for Steel (P). For stainless (M), we recommend PVD grades like AH725 to avoid the chemical bonding that leads to notch wear.

Q: What holder size do I need for CNMG160612?

A: These inserts fit any standard **DCLNR16** or **MCLNR16** holder. Be aware they are larger than the standard 1204 size.

Q: Is this insert suitable for finishing?

A: Due to the large 1.2mm radius, this is primarily for roughing and semi-finishing. For super finishing, a 0.4mm or 0.2mm radius would be better.

Expert Insight: CVD vs. PVD for Steel Turning

For high-speed CNC machining of steel, CVD Coated Carbide (T9115) is the industry benchmark. Its thicker coating provides a superior heat shield, allowing for much higher surface speeds and significantly longer tool life compared to thinner PVD coatings.

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.
