PCD Turning Car Thread Insert 16ER Cutting Tool

Material Compatibility: Primary: Aluminum alloys (high-silicon), Copper, Brass, Magnesium.

                                     Secondary: Carbon fiber, GRP/CRP composites, Plastics, and Ceramics.

Note: Not suitable for ferrous metals like Steel or Cast Iron due to chemical reaction at high temperatures.

Hardness: PCD layer hardness approx. 8000 HV, offering 50–100x the wear resistance of tungsten carbide in abrasive non-ferrous applications.

Surface Finish: Capable of achieving mirror-like finishes (low $Ra$ values) due to the extremely sharp and stable diamond cutting edge.

Cutting Speed ($Vc$): Significantly higher than carbide, typically ranging from 200 to 2000 m/min depending on the workpiece material.

Clamping System: Standard screw-on or clamp-type laydown threading tool holders (SER / SER-L).

Description

Product Information

The 16ER series is a premium line of external threading inserts designed for high-precision “Car Thread” (Lathe threading) applications. Unlike standard carbide inserts, these feature a Polycrystalline Diamond (PCD) cutting edge, making them the ultimate choice for machining non-ferrous metals and highly abrasive materials.

  • PCD Tipped Technology: Engineered with a high-hardness diamond tip brazed to a robust carbide body, providing superior wear resistance and thermal conductivity.

  • Precision Threading: Specifically designed for external threading on lathes (Turning), ensuring a high-quality surface finish and tight dimensional tolerances.

  • Cost-Efficiency: While the initial cost is higher than carbide, the significantly longer tool life and reduced machine downtime offer a much lower “cost-per-part” in mass production.
