SDNC N2020K square ISO turning insert, 15° clearance, with hole — Tungaloy

SDNCN2020K is an ISO-indexed turning insert designed for external and internal turning applications; it features a square form with a 90° included angle and a cylindrical hole with double-sided countersink for secure clamping.

• ISO indexable insert for turning
• Square form with 90° included angle
• 15° clearance angle for reliable seating
• 2.38 mm plate thickness for rigidity
• Cylindrical hole with double countersink

Reliable seating and repeatable clamping for production use

The ISO-standard geometry ensures the insert seats consistently in a matching holder, which is essential for repeatable part quality in batch production. Made from carbide, the cutting element provides the hardness needed for sustained cutting and contributes to predictable wear behaviour. The square plate form with a 90° included angle supports perpendicular approaches and simplifies toolpath planning for many turning operations. Because compatibility depends on form, 15° clearance, tolerance class, fastening and thickness, selecting a matching clamping set or holder is decisive for process stability and is emphasised in the system description.

Rigidity and cutting stability for clean surfaces

A plate thickness of 2.38 mm increases rigidity at the cutting edge and reduces vibration in interrupted cuts, which benefits surface finish and dimensional control. The absence of an integrated chipbreaker means the insert is suited where a specific chip control geometry is chosen separately; selecting an appropriate chip-control solution according to workpiece material and machining parameters supports efficient chip evacuation. In routine turning tasks — both roughing and finishing passes — the combination of carbide durability and robust plate geometry helps maintain consistent cycle times and tool life.

Secure fastening and flexible holder compatibility to reduce setup time

The cylindrical hole with double-sided countersink (70°–90°) enables a secure and centred mount, improving resistance to axial and radial forces during heavy cuts. As the insert is ISO-compatible, it integrates into standard tool systems comprising a matching external holder or boring bar, a backing pad or clamping set, and retaining screws. The system approach reduces inventory complexity: once holders and clamping kits are specified to the insert’s form, clearance and tolerance class, changeovers become faster and setup reliability improves, supporting continuous production demands.

FAQ

What workpiece materials can this insert machine effectively?
The insert is made of carbide and is suitable for a wide range of materials when paired with the correct grade and cutting parameters; SDNCN2020K is designed for general turning tasks across common steels and alloyed materials when the matching grade is selected.

How does the hole and countersink affect clamping reliability?
The cylindrical hole with double-sided countersink (70°–90°) on the SDNCN2020K ensures centred clamping and improved resistance to axial load, which reduces movement in heavy cuts and enhances repeatability.

Is a chipbreaker included with this insert?
This insert is supplied without a chipbreaker, allowing selection of a separate chip-control geometry or external chip-control measures tailored to the workpiece material and cutting strategy.

Which toolholders are compatible with this ISO insert?
Compatibility depends on holder form, clearance angle, tolerance class, fastening method, size and thickness; the insert integrates with standard ISO turning holders and boring bars specified for N2 square plates and a 15° clearance.

What system components are recommended when ordering for production?
Order matching external holders or boring bars, a backing pad or clamping set, and replacement screws alongside the SDNCN2020K to ensure correct seating and quick changeover in production setups.
