ALUMINA TURNING INSERTS

ALUMINA TURNING INSERT 
High-Performance ISO Turning Inserts
Welcome to Alumina Carbides. Here, we supply a comprehensive range of ISO Turning Inserts for modern machine shops. Specifically, these replaceable carbide tips are designed to fit standard holders on both CNC and manual lathes. Whether you are roughing down raw stock or performing delicate finishing passes, our inserts deliver consistent tool life. Therefore, you can trust our grades to keep your spindles turning.

Applications:

  • ISO turning inserts are standardized replaceable tips used in CNC and manual lathes.
  • Common shapes: CNMG, DNMG, TNMG, SNMG, VNMG, CCMT, etc.
  • Designed for roughing, finishing, and profiling operations.
  • Identified by ISO code → shape, clearance, tolerance, chipbreaker, and grade.

Key Advantages:

  • AP 4225 & AJ 525 – Steel: General-purpose grade; balanced toughness and wear resistance.
  • AMP 30 & AS 20 – Stainless Steel: Resists built-up edge (BUE); suited for sticky materials.
  • AK 1500 – Cast Iron: Excellent for abrasive materials; strong edges for brittle chips.
  • ALK 10 – Non-Ferrous: Sharp and polished edges; ideal for aluminum and copper.
  • ASM 30 – Superalloys: Withstands high heat; designed for Inconel, titanium, etc.
  • AN 20 & ASM 30 – Hardened Steel: CBN/ceramic tips for hard turning >45 HRC.

Chipbreaker

  • Roughing (CQ, PR): Heavy cuts, strong edge, large chip groove.
  • Medium (PM, GH, TM, TC, BM, MT): Balanced performance for most jobs.
  • Finishing (PF, HA, TC, BF, FG): Sharp edge, smooth surface, small DOC.
  • High Positive (AK, HA): Light cuts, low power, soft materials (e.g., aluminum).

High-Performance ISO Turning Inserts

Welcome to Alumina Carbides. Here, we supply a comprehensive range of ISO Turning Inserts for modern machine shops.

Whether you are roughing down raw stock or performing delicate finishing passes, our inserts deliver consistent tool life. Therefore, you can trust our grades to keep your spindles turning.

Optimize Your Machining by Material

Selecting the right grade is critical for success. For example, our AP 4225 grade is a general-purpose powerhouse for steel. In contrast, if you are machining stainless steel, the AMP 30 grade resists the common “built-up edge” issue. Furthermore, for abrasive materials like Cast Iron, we recommend the AK 1500 series. As a result, matching the insert to the material significantly reduces your cost per part.
