ISO Designation Breakdown

Engineering Dimensions & Geometry

Grade Details - Key Grade Characteristics

KW10 Grade Overview: KW10 is an uncoated fine-grain carbide grade equivalent to ISO K10 classification. It features a sharp cutting edge geometry optimized for low cutting forces and exceptional surface finish quality.

• Substrate: Carbide — Ultra-fine grain carbide substrate (0.5μm), high hardness (92.5 HRA), excellent wear resistance, superior edge sharpness retention, low coefficient of friction.
• Coating: Uncoated — ideal for materials prone to built-up edge
• Hardness: 92.5 HRA (typical for fine-grain uncoated grades)
• Transverse Rupture Strength: 2,800 N/mm²
• Recommended coolant: Water-soluble or oil-based; dry machining acceptable for aluminum

Grade Comparison Matrix

KW10 vs K20: KW10 offers finer grain structure for superior finish; vs coated grades: uncoated substrate prevents built-up edge on aluminum; vs ceramic: higher toughness for interrupted cuts.

Chipbreaker Profile

Chipbreaker Design: F-type chipbreaker features a positive rake angle with a narrow land width, designed specifically for finishing operations. The breaker groove creates tightly curled chips that evacuate efficiently even at low depths of cut.

Recommended Applications & Workpiece Materials

The WBGT080204L-F is optimized for the following materials and applications:

• Primary Application: Boring, Internal Facing
• Workpiece Materials: Aluminum alloys (1xxx-7xxx series), copper, brass, bronze, cast iron (gray, ductile), titanium alloys (Ti-6Al-4V), magnesium alloys, plastics, composites, non-metallic materials.
• Industry Sectors: Aerospace, automotive, medical devices, precision engineering, general manufacturing
• Machine Type: CNC turning centers, multi-tasking machines, Swiss-type lathes, sub-spindle configurations

Application Map by Operation

Boring: Ideal for internal diameter enlargement on CNC turning centers. Internal Facing: Perfect for facing operations inside bores and recesses. Sub-Spindle: Compatible with sub-spindle operations for back-side machining.

Recommended Cutting Conditions

Operating Guidelines

Use through-tool coolant for chip evacuation in deep bores. Maintain boring bar overhang ratio ≤ 4:1 (L:D). For internal facing, reduce feed rate by 20% compared to external operations. Verify concentricity before sub-spindle transfer.

• Always verify insert seat cleanliness before mounting
• Use torque wrench for clamping screws (recommended 2.5-3.5 N·m)
• Monitor flank wear; replace when VBmax = 0.15-0.20 mm
• Store inserts in original packaging away from direct sunlight and moisture
• For aluminum machining, use polished inserts to prevent built-up edge

Toolholder Compatibility

Compatible with WBGT series boring bars and internal turning tools. Use Kyocera ISOI holder series or equivalent with 95° approach angle. Minimum boring diameter: 8mm.

Packaging & Ordering Information

Each insert is precision-packed in individual plastic pockets within a 10-piece Kyocera labeled container. MPN TWE series packaging includes rust-inhibitor coating.
