Grade Details - Key Grade Characteristics
Grade KW10 is a fine-grained uncoated carbide substrate classified under the ISO K10 range. It offers high hardness, excellent wear resistance, and superior edge stability for light to medium machining operations. The absence of coating makes it ideal for applications where built-up edge must be minimized and where sharp cutting edges are paramount.
- High hardness and abrasion resistance
- Excellent surface finish capability
- Stable performance in non-ferrous and cast iron materials
- Optimized micro-grain structure for edge stability
Grade Comparison Matrix
| Grade | Coating | ISO Range | Best For |
|---|---|---|---|
| KW10 | Uncoated | K10 | Cast iron, non-ferrous, plastics, titanium |
| KW20 | Uncoated | K20 | General purpose, interrupted cuts |
| CA530 | CVD Coated | P30 | Steel machining at higher speeds |
Chipbreaker Profile
This insert features a precision-ground cutting edge without a dedicated chipbreaker profile, optimized for back turning where minimal cutting interference and maximum edge stability are required. The natural chip flow geometry ensures reliable chip evacuation at moderate feeds.
Recommended Applications & Workpiece Materials
- Cast iron (gray, ductile, malleable)
- Non-ferrous metals (aluminum, copper, brass, bronze)
- Non-metallic materials (plastics, composites, wood)
- Titanium alloys and heat-resistant materials
- Back Turning operations on CNC lathes and turning centers
Application Map by Operation
| Operation | Suitability | Notes |
|---|---|---|
| Back Turning | Primary | Optimized geometry for this operation |
| Roughing | Limited | Light roughing only; not for heavy interrupted cuts |
| Finishing | Excellent | Delivers mirror-quality surface finishes |
| High-Speed Machining | Good | Use with stable setups and adequate coolant |
Recommended Cutting Conditions
| Workpiece Material | Cutting Speed (m/min) | Feed (mm/rev) | Depth of Cut (mm) |
|---|---|---|---|
| Gray Cast Iron | 80-150 | 0.05-0.20 | 0.5-3.0 |
| Aluminum Alloy | 200-400 | 0.05-0.15 | 0.5-2.0 |
| Brass / Bronze | 100-250 | 0.05-0.20 | 0.5-2.5 |
| Titanium Alloy | 30-60 | 0.05-0.12 | 0.3-1.5 |
Operating Guidelines
- Ensure rigid workpiece clamping and minimal tool overhang for best results
- Use adequate coolant flow to prevent thermal cracking and built-up edge
- Verify insert seat condition before indexing to avoid micro-chipping
- Start at the lower end of recommended speeds for new setups
- Monitor chip formation; adjust feed if chips are too fine or too heavy
- For titanium and heat-resistant alloys, use high-pressure coolant when possible
Toolholder Compatibility
The TKFB16R38005M is designed for use with KTKF series back turning toolholders, compatible with TKFB-style clamping systems. Always verify toolholder pocket geometry, clamping mechanism, and coolant delivery compatibility before operation. Use genuine Kyocera toolholders to ensure optimal insert positioning and repeatability.
