4. Grade Details – Key Grade Characteristics

The KW10 grade is a fine-grained uncoated carbide optimized for high-speed finishing and semi-finishing of non-ferrous materials. Key characteristics include:

• Substrate: Ultra-fine grain carbide with high hardness and excellent wear resistance
• Coating: Uncoated – ideal for machining materials where built-up edge is a concern
• ISO Application Group: K10 classification for machining cast iron, non-ferrous metals (aluminum, copper, brass), plastics, and titanium alloys
• Edge Preparation: Sharp cutting edge optimized for low cutting forces and minimal burr formation
• Thermal Stability: Maintains hardness at elevated temperatures during dry machining

6. Chipbreaker Profile

The A3 chipbreaker geometry is specifically engineered for turning operations with the following features:

• Land Width: Narrow land design for reduced cutting pressure and improved surface finish
• Groove Depth: Optimized for chip curling and controlled breakage in finishing to medium machining
• Chip Control: Effective chip evacuation for both short-chipping (cast iron) and long-chipping (aluminum) materials
• Edge Stability: Reinforced cutting edge corner for improved resistance to chipping under intermittent cuts

7. Recommended Applications & Workpiece Materials

This insert excels in the following material groups and application scenarios:

• Aluminum & Aluminum Alloys: Excellent mirror finish capability due to sharp uncoated edge preventing built-up edge
• Copper & Brass: Ideal for electrical component machining requiring burr-free edges
• Cast Iron (Gray & Ductile): Stable performance in finishing operations with good wear resistance
• Titanium Alloys: Suitable for low-speed, high-precision titanium finishing where heat generation must be minimized
• Plastics & Composites: Clean cuts without material melting or fiber pull-out

9. Recommended Cutting Conditions

Starting parameters for KW10 uncoated carbide. Adjust based on machine rigidity and workpiece condition:

10. Operating Guidelines

• Tool Presetting: Ensure insert seating surface is clean and free of chips before clamping
• Cutting Fluid: Not mandatory for aluminum and cast iron; flood coolant recommended for titanium to prevent work hardening
• Depth of Cut: Do not exceed 2× corner radius for finishing passes to maintain surface quality
• Speed Ramp: Start at lower Vc and increase gradually while monitoring tool wear and surface finish
• Insert Change: Index to fresh edge when flank wear exceeds 0.15 mm or when surface finish degrades
• Storage: Keep inserts in original packaging away from moisture and corrosive environments

11. Toolholder Compatibility

This 55 degree diamond insert requires compatible right hand toolholders with the following characteristics:

• Toolholder Series: DCGT – ISOI standard holders
• Clamp System: Lever lock or top-clamp for secure insert retention
• Insert Seat Angle: Must match 55° included angle
• Shank Size: Select based on machine turret and workpiece reach requirements
• Coolant Delivery: Through-tool coolant holders recommended for deep cavity machining
