Kyocera CCMT060204HQ CA115P TML00322 Diamond Insert - Steel Roughing

Product Overview

The CCMT060204HQ CA115P TML00322 is a premium 80° diamond indexable insert engineered by Kyocera for demanding CNC turning operations. Featuring a heavy-duty quality chipbreaker and 0.4 mm nose radius, this insert delivers exceptional chip control and surface finish on steel and stainless steel workpieces. The PVD TiAlN-coated fine-grained carbide substrate ensures extended tool life even at elevated cutting speeds, making it ideal for high-volume production environments where consistency and reliability are paramount.

ISO Designation Breakdown

The CCMT060204HQ designation follows the ISO 1832 standard for indexable inserts. Each character in the code specifies a critical geometric or functional parameter:

Recommended Cutting Conditions

Start with these parameters and optimize based on your machine rigidity and workpiece condition:

Note: Values are starting recommendations. Adjust based on machine power, rigidity, and coolant application.

Operating Guidelines

Follow these best practices to maximize tool life and part quality:

• Entry Angle: Use 45°-75° entering angle for optimal chip control and reduced notch wear.
• Coolant: High-pressure coolant (70+ bar) recommended for stainless steel and deep cavity work.
• Dry Machining: CA115P grade is optimized for dry cutting; coolant may cause thermal shock in interrupted cuts.
• Edge Preparation: Do not re-sharpen or re-coat. Insert is designed for single-use indexing.
• Tool Overhang: Minimize overhang to 4× insert size for stable cutting and reduced vibration.
• Chip Management: Ensure adequate chip evacuation to prevent recutting and premature flank wear.
• Workpiece Preparation: Remove scale and surface defects before finishing operations to protect cutting edge.
• Speed Ramp: Reduce speed by 15% for first 2 minutes to allow thermal stabilization of the coating.
• Roughing Note: Increase feed rate gradually to avoid overload; use rigid setup for interrupted cuts.

Toolholder Compatibility

The CCMT060204HQ is compatible with standard ISO toolholders. Recommended holder families:

• Compatible Holders: MCLN / MCKN / MCGN (80° diamond)
• Clamping Method: Screw clamp (for hole-type inserts) or lever lock
• Holder Material: Alloy steel, heat-treated to 45-50 HRC
• Insert Seat: Precision ground to match insert shape and clearance angle
• Coolant Delivery: Through-tool coolant recommended for optimal chip evacuation
