Description

Introduction:

The SDMT150512 high-feed milling insert is designed for high-speed and high-feed machining applications. With optimized cutting geometry and reinforced cutting edges, this carbide insert ensures low cutting resistance, stable performance, and excellent chip evacuation.

Manufactured from high-quality tungsten carbide substrate and coated with advanced PVD/CVD technology, the insert delivers superior wear resistance, heat resistance, and long tool life under demanding machining conditions.

This High-Feed Milling Insert is suitable for:

Alloy steel milling

Stainless steel machining

Cast iron cutting

Mold and die machining

Automotive component production

The double-sided design increases cost efficiency and maximizes productivity, making it an ideal solution for roughing and semi-finishing operations.

 

  1. Low Entering Angle Geometry

The insert utilizes a small entering angle (typically 10°-17°), transforming radial cutting forces into axial forces. This significantly reduces vibration and improves machining stability, especially on long overhang tools and less rigid setups.

  1. High Feed Capability with Chip Thinning Effect

The chip thinning principle allows feed rates 2-4 times higher than conventional 90° milling insert while maintaining controlled chip thickness. This increases productivity without increasing cutting depth.

  1. Reinforced Cutting Edge Preparation

Special edge honing or chamfering strengthens the cutting edge, improving resistance to chipping and ensuring reliable performance under high feed and heavy load conditions.

  1. Advanced Coating Technology

Available with high-performance PVD/CVD coatings such as TiAlN or AlTiN, providing excellent wear resistance, thermal stability, and oxidation resistance for high-speed machining applications.

  1. Optimized Carbide Substrate

Fine-grain carbide substrate ensures an ideal balance between hardness and toughness, offering outstanding resistance to thermal cracking and plastic deformation.
