Product Overview

The CCGT030104L-F Grade KW10 Uncoated Carbide Turning Insert is a precision-engineered indexable insert manufactured by Kyocera in China. Designed for boring, external turning, facing, internal facing, sub-spindle, this 80 degree diamond insert delivers exceptional surface finish, dimensional accuracy, and extended tool life on CNC turning centers and milling machines.

With 2 usable cutting edges and a 1/64" (0.4mm) nose radius, the CCGT030104L-F minimizes cutting forces and enhances chip control, ensuring consistent and repeatable results across high-volume production runs. The KW10 substrate provides the ideal balance of hardness and toughness for machining non-ferrous metals, cast iron, and non-metallic materials.

ISO Designation Breakdown

The ISO code CCGT030104L-F follows the standard ISO 1832 nomenclature for indexable inserts:

Engineering Dimensions & Geometry

Grade Details - Key Grade Characteristics

Kyocera Grade KW10 is a premium uncoated fine-grained tungsten carbide grade with a cobalt binder matrix. Classified under the ISO K10 group, this grade delivers exceptional hardness and abrasion resistance for precision machining applications.

• Substrate: Ultra-fine WC-Co grain structure (0.5–0.8 μm)
• Hardness: 92.0 HRA (approx. 1600 HV30)
• Transverse Rupture Strength: >2,800 MPa
• Binder Content: 6% Co
• Coating: None (uncoated for maximum edge sharpness)
• Color Code: Gray (uncoated carbide)

The absence of coating preserves a razor-sharp cutting edge essential for mirror-finish machining on non-ferrous metals, cast iron, and non-metallic materials. The fine grain structure minimizes micro-chipping and ensures consistent tool life in high-speed finishing operations.

Grade Comparison Matrix

Selection Guidance: Choose KW10 when maximum edge sharpness and surface finish are required on non-ferrous or cast iron workpieces. For roughing or interrupted cuts in cast iron, consider KW20 or coated alternatives.

Chipbreaker Profile

The F-type chipbreaker features a narrow, shallow groove designed for light cutting depths and low feed rates. Ideal for finishing operations requiring superior surface finish on non-ferrous materials and cast iron.

Recommended Applications & Workpiece Materials

The KW10 grade is specifically formulated for stable cutting of cast iron, non-ferrous materials, non-metals, and titanium alloys. The uncoated substrate maintains a sharp cutting edge without built-up edge formation, making it ideal for:

• Aluminum & Aluminum Alloys: Mirror-finish turning on Al-Si alloys up to 12% silicon content. Prevents material adhesion and built-up edge.
• Copper & Brass: Excellent for electrical component machining where surface conductivity is critical. No coating contamination.
• Gray & Ductile Cast Iron: Stable performance in continuous and lightly interrupted cuts. Abrasion resistance from fine WC grain structure.
• Titanium Alloys: Low cutting speeds with sharp edge reduce work-hardening and extend tool life in Ti-6Al-4V applications.
• Plastics & Composites: Clean cutting without delamination or fiber pull-out in GFRP and CFRP materials.
• Non-Metallic Materials: Suitable for graphite, ceramics, and engineered plastics requiring high precision.

Application Map by Operation

Recommended Cutting Conditions

Starting parameters for KW10 grade in common workpiece materials. Adjust based on machine condition and setup rigidity:

Note: Values are starting recommendations. Adjust based on machine rigidity, workpiece condition, and coolant application. Dry machining is recommended for aluminum and non-ferrous materials to prevent built-up edge.

Operating Guidelines

• Edge Preparation: This insert comes with a precision-honed edge (T-land or sharp edge depending on radius). Do not re-hone unless using specialized equipment.
• Coolant Recommendation: Flood coolant recommended for cast iron and titanium. Air blast or minimal quantity lubrication (MQL) preferred for aluminum to prevent thermal cracking.
• Toolholder Overhang: Keep overhang-to-diameter ratio below 4:1 for boring operations to minimize chatter.
• Insert Seat Cleaning: Always clean the toolholder pocket and ensure proper seat contact before insert installation. Poor contact reduces heat dissipation and causes premature failure.
• Torque Setting: Tighten clamping screw to 2.5–3.5 N·m using a torque wrench. Over-tightening causes insert fracture; under-tightening leads to micro-vibration and poor finish.
• Storage: Store in original packaging away from moisture and corrosive environments. Uncoated carbide is susceptible to oxidation in humid conditions over extended periods.

Toolholder Compatibility

SCLCR/L, MCLNR/L, DCLNR/L series toolholders with 80° diamond insert pockets. Left-Hand toolholders required. Compatible with Kyocera standard toolholders and industry-standard ISO toolholders.
