DCGT 11T304 SH725 — ISO rhombic turning insert, coated carbide by Tungaloy

The DCGT 11T304 SH725 is a rhombic ISO turning insert designed for external and internal turning, offering a tough, cutting-edge-stable coated-carbide grade for variable engagement conditions.

• ISO rhombic insert for turning, 55° included angle
• SH725 coated carbide for stable cutting edges
• 0.4 mm corner radius for precise finishes
• One-sided chipbreaker, hole with countersink

Reliable grade for variable machining conditions

The SH725 grade is a coated carbide formulation developed for toughness and stable cutting edges under fluctuating engagement and smaller-tool scenarios. In practical terms, this means longer intervals between insert changes and reduced scrap rates when encountering intermittent cuts or uneven stock. The combination of coating and substrate supports consistent wear patterns, allowing process engineers to predict tool life more reliably and to plan production runs with fewer interruptions.

Geometry tuned for finish and rigidity

A 55° rhombic profile provides versatile cutting entry angles for both external and internal turning operations, while the 0.4 mm corner radius helps achieve finer surface finishes without compromising strength at the cutting edge. The 7° relief angle minimises flank contact and the 3.97 mm thickness contributes to insert rigidity, reducing vibration and improving dimensional stability. These geometric choices balance surface quality with robustness, making the insert suitable where repeatable tolerances and good finishes are required.

Compatibility, clamping and chip control

As part of the ISO series, compatibility with external holders is determined by form, relief angle, tolerance class, fastening, size and thickness. The insert features a cylindrical hole with single-sided countersink (40°–60°) and a one-sided chipbreaker, which together enable secure clamping and controlled chip flow in many turning setups. When selecting a toolholder and clamping set, match the holder form and tolerance class to the insert dimensions to ensure repeatable seating and torque transmission.

Recommended applications and selection guidance

The insert is intended for general turning tasks where changing cutting conditions or limited overhangs are common; it is especially appropriate for smaller tooling systems and mixed-production environments. Choose the one-sided chipbreaker and the SH725 grade to favour toughness and edge stability; when facing different workpiece materials or harder conditions, adapt the chipformer and cutting parameters accordingly. For process optimisation, pair the insert with holders that provide minimal runout and good rigidity to exploit the coated carbide benefits fully.

FAQ

What holders are compatible with this insert?
Compatibility is determined by the insert form, relief angle, tolerance class, fastening and thickness; the DCGT 11T304 SH725 fits ISO-compatible external holders designed for DCGT inserts.

For which turning tasks is this grade recommended?
The SH725 grade is recommended for turning operations with variable engagement and smaller-tool set-ups where edge stability and toughness are priorities.

How does the 0.4 mm corner radius affect surface finish?
A 0.4 mm corner radius balances edge strength and surface quality, improving finish compared with larger radii while maintaining robustness under intermittent cuts.

What is the purpose of the single-sided chipbreaker?
The one-sided chipbreaker controls chip formation and evacuation for many turning scenarios; pairing it with appropriate feeds helps maintain steady cutting conditions.

What should be checked before mounting the insert?
Ensure the holder matches the ISO form, verify seating flatness and tolerance class, and confirm the clamping screw and pad align with the insert hole and countersink.
