Description

TaeguTec TNMG 160412 PC TT8115

Engineered for High-Speed Cast Iron and Stable Steel Machining

Product Overview

"Which insert is best for high-speed turning of cast iron components while maintaining a high feed rate and superior tool life?"

The TaeguTec TNMG 160412 PC TT8115 is a premium CVD-coated carbide insert built for maximum productivity. The TT8115 grade features an ultra-hard substrate combined with a thick alumina coating, providing unmatched wear resistance in ISO K (Cast Iron) and high-speed ISO P (Steel) applications. This model is paired with the PC (Positive Cut) chipbreaker, designed to reduce radial cutting forces and heat build-up. With its 1.2mm corner radius, this insert allows for significantly higher feed rates compared to standard 0.4mm or 0.8mm models, making it the perfect solution for large-diameter turning and high-productivity finishing.

Core Performance Advantages

TT8115 Wear Resistance

Optimized for abrasive materials like Grey and Nodular Cast Iron. Exceptional resistance to crater and flank wear.

PC Low-Force Logic

The sharp positive geometry slices through the workpiece, minimizing machine spindle load and preventing vibration.

High-Feed Finishing

The 1.2mm radius allows for faster table feeds without sacrificing surface quality, shortening overall cycle times.

Why Choose TaeguTec TT8115?

In high-speed production environments, downtime for tool changes is profit lost. The TaeguTec TT8115 grade is engineered with a substrate that resists the intense heat generated when cutting abrasive cast irons. By utilizing the PC chipbreaker, this insert prevents the common issue of work hardening and excessive spindle load. The larger 1.2mm corner radius further enhances the durability of the cutting edge, ensuring dimensionally accurate parts through long production shifts.

Frequently Asked Questions

Q: Is TT8115 suitable for interrupted cuts?
A: TT8115 is a very hard grade optimized for continuous high-speed turning. For heavy interrupted cuts, we recommend the tougher TT8125 grade.
Q: Can I use this on Stainless Steel?
A: No. The coating and substrate are optimized for Iron and Steel. For Stainless (ISO M), please use TaeguTec TT9080 or TT5080.
Q: Why use a 1.2mm radius over 0.8mm?
A: A larger radius provides a stronger cutting edge and allows for higher feed rates (fn) while maintaining the same surface finish quality.

Machining Tip: CVD grades like TT8115 are best for thermal resistance in stable applications. Always prioritize the 1.2mm radius when the part geometry allows for increased productivity.

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.

When will my order ship and arrive?

According to our shipping policy, orders are typically processed and shipped within 1–3 business days after confirmation. Delivery generally takes 5–20 business days, depending on your destination and shipping method. Customs clearance or unforeseen delays may affect delivery times.
