With 2 precision-ground cutting edges, the ABW23R5015 offers cost-efficient performance for high-volume production environments.

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: This insert features a precision-ground cutting edge without a dedicated chipbreaker groove, optimized for ultra-fine finishing and low-depth-of-cut applications where chip control is managed through cutting parameters.

Recommended Applications & Workpiece Materials

The ABW23R5015 is optimized for the following materials and applications:

• Primary Application: Back Turning
• 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

Back Turning: Primary application for facing and back-turning operations on CNC lathes. Suitable for small-diameter workpieces where conventional turning is restricted.

Recommended Cutting Conditions

Operating Guidelines

Use minimum coolant flow to prevent thermal shock. Ensure toolholder rigidity—minimum overhang of 1.5x diameter. For back turning, approach angle should not exceed 93°. Verify insert seating with dial indicator before operation.

• 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 ABS/ABW series back-turning toolholders. Use Kyocera APBT holder series or equivalent ISO-compliant holders with 93° approach angle.

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 and impact-resistant foam.
