TaeguTec TDC4 TT9080
Maximum Edge Security: The 4.0mm Solution for Severe Interrupted Cuts
Product Overview
"Which 4mm parting insert is tough enough to handle heavy interrupted cuts in alloy steel without chipping the cutting edge?"
The TaeguTec TDC4 TT9080 is engineered for "worst-case scenario" machining. When dealing with large diameter Hex Bars, cross-holes, or unstable workholding, standard grades often fail due to mechanical shock. The TT9080 PVD grade features a specialized high-toughness substrate that acts as a shock absorber. Combined with the 4.0mm TDC chipbreaker, which uses a concave geometry to compress chips narrower than the slot, this insert provides unrivaled stability. It is the industrial choice for Steel (ISO P) and Stainless Steel (ISO M) where process security is more critical than pure cutting speed.
Core Advantages
Unique multi-layer PVD coating designed to prevent crack propagation during heavy interrupted machining cycles.
The 4mm width offers maximum lateral support, drastically reducing vibration in deep grooves or large radial parting.
The TDC breaker folds chips into a "C" shape narrower than 4mm, eliminating sidewall friction and surface damage.

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.
