CCMW09T308 UC5115
Cast Iron Heavy-Duty Specialist | Reinforced Flat-Top | UC5115 CVD Grade
Engineered for Abrasive Environments
UC5115 Grade (CVD Coating): The UC5115 grade is a dedicated Cast Iron Specialist. It features a thick, highly-adherent Alumina (Al2O3) CVD coating that acts as a thermal shield. This allows for extreme surface speeds while protecting the carbide substrate from the micro-abrasions caused by the graphite flakes and sand inclusions common in cast iron.
CCMW Geometry (Non-Chipbreaker): The Flat-Top (CCMW) design is intentional. Cast iron produces short, segmented chips that do not need to be mechanically curled. By removing the chipbreaker groove, the cutting edge remains at its maximum thickness, drastically increasing Edge Strength and resistance to chipping under high-load conditions.
0.8mm High-Strength Radius: The 08 (1/32") radius is the tank of the CCMW series. It distributes cutting pressure over a larger area than a 0.4mm radius, making it ideal for Roughing and Semi-Finishing where the surface may have scale or casting crust.
Metric vs. Imperial Comparison
| System | Model Designation | I.C. (Inscribed Circle) | Thickness | Radius (RE) |
|---|---|---|---|---|
| Metric | CCMW09T308 | 9.525 mm | 3.97 mm | 0.80 mm |
| Imperial | CCMW32.52 | 3/8" | 5/32" | 0.0315" (1/32") |
Recommended Cutting Parameters
*UC5115 excels in high-speed dry machining. When machining ductile iron, ensure stable feed rates to avoid work hardening.
| Workpiece Material | Speed (Vc) | Feed (fn) | Depth (Ap) |
|---|---|---|---|
| Gray Cast Iron (GG25) | 180 - 450 m/min | 0.15 - 0.40 mm/r | 0.80 - 3.50 mm |
| Ductile Cast Iron (GGG60) | 130 - 320 m/min | 0.12 - 0.35 mm/r | 0.80 - 3.00 mm |

CCMW09T308 (0.8mm Radius): Use for roughing or when the surface has heavy scale. The larger radius provides the toughness needed to survive high feed rates in gray iron.
CCMW09T304 (0.4mm Radius): Use for finishing or when machining thin-walled cast iron parts to reduce cutting pressure and prevent deformation.

Technical FAQ & Buying Guide
When choosing CNC cutting tools, check the full model code, dimensions, grade and selected variant before ordering. Do not rely on the product image alone.
For carbide inserts, tool holders, drills and end mills, compare the mounting dimensions, connection type and manufacturer's specifications with your holder or machine. If you are unsure, share your existing part number and machining application with us before ordering.
Check the product listing for the selling unit, pack quantity and included components. If it is unclear whether the price is per piece or per pack, or whether a tool body and inserts are sold separately, contact us before purchasing.
Select cutting speed, feed rate and depth of cut using the relevant manufacturer's recommendations for your tool model, workpiece material, machine conditions and coolant method. The same settings are not suitable for every product or application.
