SDJC SDJCR2020K R2020K turning insert – Tungaloy

The SDJCR2020K Tungaloy turning insert is an ISO-standard, square cemented carbide insert engineered for external and internal turning applications, compatible with holders defined by form, clearance angle, tolerance class, fixing and plate dimensions.

• ISO-standard square carbide insert SDJCR2020K
• 15° relief angle for precise cutting
• Cylindrical hole with double countersink 70°–90°

Consistent interchangeability reduces set-up time and error

The ISO conformity of the series ensures reliable interchangeability between inserts and holders, which reduces downtime and simplifies inventory. The square geometry and clearly defined fixing dimensions allow fast indexing and repeatable seating in the clamping system; the 90° included angle contributes to predictable cutting engagement. Thanks to the 15° relief angle, flank contact is reduced, promoting stable cutting conditions and predictable tool life.

Cemented carbide construction for stable cutting performance

Manufactured from cemented carbide, the insert provides a stable cutting edge and wear resistance appropriate for a broad range of turning tasks. The model series advises selecting an appropriate chipbreaker and grade to match workpiece material and machining stability; this guidance supports both efficient material removal and improved surface finish. The absence of an integrated chipbreaker means the chip control strategy can be tailored through grade and holder selection for specific applications.

Design details that improve clamping and repeatability

Attention to mounting features simplifies assembly and maintenance: the plate has a 2.38 mm thickness, square geometry, and a corner radius R2 for defined edge strength. The cylindrical hole and the double countersink (70°–90°) permit secure screw engagement and reliable seating, minimising micro-movements under cutting forces. These design choices contribute directly to dimensional repeatability and reduce the frequency of re-setting operations on production lines.

System approach for productive machining and quick replacement

The insert is conceived as part of a complete system: an ISO turning insert combined with a matching external holder or boring bar, shim/clamp set and spare screws ensures stable clamping and straightforward replacement routines. This system mindset supports higher uptime and consistent results in continuous production. For applications that require precise process tuning, consulting the technical documentation or Metav Werkzeuge’s consultants assists in selecting the optimal grade and mounting configuration for productive machining.
