TaeguTec SPMG060204DG TT8020
High-Performance Drilling: Optimized Stability for Steel & Stainless Steel
Product Overview
"Which indexable insert is best for stable hole making in alloy steel while ensuring smooth chip evacuation in deep-hole drilling?"
The TaeguTec SPMG060204DG TT8020 is a premium indexable drilling insert designed for the DrillRush and standard indexable drill families. Featuring the TT8020 grade, it utilizes a specialized PVD coating over a tough sub-micron substrate, providing excellent resistance to heat and chipping. The DG chipbreaker is specifically engineered for drilling applications; its unique geometry breaks chips into small, manageable "C" shapes, preventing flute clogging and ensuring continuous operation in both ISO P (Steel) and ISO M (Stainless Steel) materials.
Key Features
Advanced multi-layered AlTiN coating provides extreme hardness and thermal stability, extending tool life in high-speed drilling.
Optimized for drilling: reduces cutting resistance and ensures excellent chip breaking even at varying feed rates.
Reinforced cutting edges minimize micro-chipping during the high-impact entry and exit phases of the drilling process.

Why Trust TaeguTec SPMG?
The SPMG060204DG is the result of South Korean precision engineering. By utilizing the TT8020 PVD grade, TaeguTec ensures that users experience fewer tool changes and higher reliability. Whether you are running a single CNC machine or a high-volume production line, these inserts deliver the predictability required for modern "lights-out" manufacturing.
"Excellent Stability" - Switched to SPMG DG for our stainless manifold job. Zero flute clogging issues.
— Workshop Manager (USA)Sehr gute Standzeit in 42CrMo4. Die Spankontrolle ist hervorragend.
— CNC Spezialist (Germany)Ottimo grado TT8020. Resistente al calore anche a secco.
— Meccanica Generale (Italy)Predictable wear patterns. Makes planning production much easier.
— Tooling Tech (Japan)Frequently Asked Questions
1. Can I use SPMG inserts in both the peripheral and central pockets?
Yes, the SPMG square design allows the same insert to be used in both positions on compatible TopDrill bodies, simplifying your inventory.
2. Is TT8020 better for dry or wet drilling?
While TT8020 has high thermal stability, internal coolant is highly recommended for drilling to ensure chip evacuation and prevent heat build-up in the hole.

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.
