DCMT070208 GT9530 rhombic turning insert for turning — Tungaloy

The DCMT070208 GT9530 is an ISO-standard rhombic indexable turning insert intended for finishing and light general-purpose turning in steel under stable machining conditions.

• Coated cermet grade GT9530 for long tool life
• ISO rhombic DCMT070208 geometry
• 7° clearance angle for stable finishing
• 0.8 mm nose radius for superior surface finish

High-quality finishing with extended wear resistance

The coated cermet composition of this indexable insert delivers a balance between wear resistance and surface integrity. The GT9530 grade is designed for wear-resistant finishing and light universal applications in steel, providing longer component life under stable setups. The 0.8 mm nose radius reduces scallop height and enables improved visual and dimensional surface quality, translating into fewer downstream operations and a lower cost per part. This combination supports predictable machining cycles and contributes directly to production efficiency.

Secure mounting and consistent repeatability

Rhombic geometry and ISO conformity mean the insert integrates into standard tool systems with predictable seating and clamping behaviour. Compatibility with a holder depends on form, clearance, tolerance class, fastening, size and thickness — factors that ensure secure location and repeatable results. The 7° clearance minimises rubbing at the flank and improves tool life during finishing passes. The insert includes a cylindrical hole + single-side countersink (40°–60°) for reliable fixing, while the 2.38 mm plate thickness enhances rigidity in the cutting zone, reducing vibration and maintaining dimensional accuracy.

Practical machining guidance for turning steel

Intended for external and internal turning, this insert performs best when paired with an appropriate one-sided chipbreaker and stable tool overhang. The geometric choices suit finishing and light turning where surface quality and tool life are priorities; select the chipbreaker and grade according to workpiece material and machine stability. The insert is especially effective in stable set-ups where consistent cutting engagement is maintained, leading to fewer interruptions and more predictable process control. Where higher stability is present, feed and depth can be adjusted to favour productivity while retaining the desired finish.

Integration into the tooling system and stock strategy

The ISO designation simplifies procurement and inventory control by matching a recognised geometry to compatible holders, shims and clamping kits. Typical system components include the indexable insert, a compatible external holder or boring bar, a shim or clamping set, and replacement screws — all chosen to match the insert’s form, free angle and tolerance. Keeping a small selection of this grade and size on hand supports quick changeovers for finishing operations and reduces machine downtime, delivering a practical balance of availability and performance.

FAQ

What materials is this insert suitable for?
The DCMT070208 GT9530 insert is designed primarily for machining steel and is optimised for finishing and light universal turning under stable conditions.

How does the GT9530 grade affect tool life and finish?
The GT9530 coated cermet grade provides enhanced wear resistance and a fine surface finish, extending tool life in finishing applications while maintaining consistent component quality.

Which holders are compatible with this insert?
Compatibility depends on the holder’s form, clearance, tolerance class, fastening method, size and thickness; the ISO rhombic DCMT070208 profile ensures fitment with standard ISO external holders and boring bars that accept rhombic inserts.

What does the cylindrical hole with single-side countersink provide?
The cylindrical hole + single-side countersink (40°–60°) offers secure clamping and precise location, improving repeatability and minimising movement under cutting forces.

Is the DCMT070208 GT9530 suitable for internal turning?
Yes, the insert is suitable for internal turning as well as external operations, particularly when a finishing pass is required and the machining set-up provides sufficient rigidity.
