Hook / Attention Line

Do more with less downtime — the Kyocera CCMT09T304HQ CJ225P turning insert from CNC Tools Depot offers the perfect mix of toughness, wear resistance, and consistency.

Key Features & Specs

  • Geometry & Design: CCMT — an 80° rhombic (diamond) insert with neutral hand and HQ chipbreaker ensures stable cutting, great chip evacuation, and strong corner strength. According to Kyocera’s turning catalog, CCMT 09T304HQ geometry provides proven reliability. 

  • Grade & Coating: CJ225P — a CVD-coated carbide grade from Kyocera’s indexable turning portfolio. This grade is built for steel and stainless, delivering excellent thermal stability and wear resistance. 

  • Dimensions & Spec Highlights:

    • Inscribed Circle (I.C.): ~ 9.53 mm (09T3 series) 

    • Thickness: ~ 3.97 mm for 09T304 variants.

    • Relief Angle: ~ 7° (standard for HQ geometry).

      Corner Radius Options: Commonly 0.4 mm for 09T304; other variants exist. 

Why It’s a Best Seller:

  • Extended Tool Life: CJ225P’s robust CVD coating resists wear even under high temperatures — so you change inserts less often.

  • Less Downtime: Stable cutting performance and the HQ chipbreaker reduce the risk of edge chipping or breakage.

  • Consistent Surface Finish: Exceptional edge integrity helps you maintain tight tolerances and smoother finishes, minimizing rework.

  • Cost Efficiency: More parts per insert, fewer tool changes — this drives down the cost per component directly.

🏭 Application Industries

This insert shines in:

  • Turning / External & Internal Turning of steel & stainless steel

  • Facing / Boring operations where durability + surface quality matter

  • Industries like automotive, aerospace, die & mold, general engineering, tool & gauge, and machine shops

Frequently Asked Questions

This insert is optimized for steel and stainless steel turning, leveraging the CJ225P grade’s toughness and wear resistance

It uses HQ chipbreaker — a general-purpose geometry that supports medium to heavy cutting with reliable chip control.

The CCMT geometry typically provides 2 usable edges per insert (diamond shape) when using neutral-hand inserts

Commonly a 0.4 mm corner radius (09T304). Other variants like 0.8 mm (09T308) are also available in similar grades

CJ225P is a CVD-coated carbide grade offering a great balance: high wear resistance + toughness + thermal stability → less frequent tool changes and longer edges, reducing overall tooling cost.
