DCMT 070208 GT9530 indexable turning insert for turning — Tungaloy

DCMT 070208 GT9530 is a coated cermet indexable insert optimised for finishing and light universal turning in steel, offering high wear resistance and consistent surface quality.

• Coated cermet grade GT9530 for steel
• Ideal for finishing and light general use
• Rhombic DCMT geometry, 55° relief angle
• Single-sided chipbreaker with bore and countersink

Consistent finish and extended tool life with a wear-resistant cermet

The GT9530 coating on a cemented carbide substrate delivers a balance between wear resistance and edge strength that is particularly suited to finishing operations in stable setups. This wear-resistant grade reduces flank wear and helps maintain dimensional accuracy over longer production runs, which translates into fewer tool changes and lower downtime. The improved edge integrity also promotes a superior surface finish, reducing rework and ensuring repeatable part quality for batch production.

Geometry and clamping: predictable performance across holders

The rhombic DCMT form with a 55° approach angle and a 7° clearance provides predictable chip flow and consistent engagement in external and internal turning. The single-sided chipbreaker is designed for light to finishing cuts and is combined with a central hole featuring a cylindrical bore and a one-sided countersink (40°–60°) for secure clamping. Compatibility with the toolholder is determined by insert form, clearance, tolerance class, fastening method, size and thickness; these parameters ensure repeatable seating and torque transfer when used with the appropriate external holder, shim and clamping screw.

Practical application advice for reliable machining results

Engineered for turning of steel under stable conditions, this indexable insert performs best when matched to a stable setup and the correct chipbreaker for the chosen feed and depth of cut. The 0.8 mm corner radius helps to blend surface peaks and improve part aesthetics while maintaining edge strength for light interrupted cuts. Select the appropriate chipbreaker and holder combination based on the component geometry and machining strategy to exploit the insert’s productive potential and achieve consistent cycle time and surface integrity.

FAQ

What workpiece materials is this insert suited for? The DCMT 070208 GT9530 insert is specified for the machining of steel and is optimised for finishing and light universal turning when stable clamping and cutting conditions are provided.

How does the GT9530 grade affect tool life and finish? GT9530 is a coated cermet designed for wear resistance and surface quality; the grade extends tool life under finishing conditions while producing consistent surface finishes on steel components.

Which holders are compatible with this DCMT insert? Compatibility depends on the insert form, clearance, tolerance class, fastening, size and thickness; the DCMT geometry fits standard ISO external holders and appropriate clamping sets that accept size 07, 2.38 mm thick inserts.

Can the insert be used for interrupted cuts? The 0.8 mm corner radius increases edge robustness, allowing limited interrupted cutting, but the grade and chipbreaker are optimised for finishing and light general-purpose use, so stable conditions are recommended for best performance.

What is the significance of the central bore and countersink? The cylindrical bore with a one-sided countersink (40°–60°) secures the insert in the clamping system and ensures correct seating and repeatable orientation in the holder.
