CCMT060202 UE6020
Steel Machining Specialist | CVD Coated Carbide | 0.2mm Radius
Material & Geometry Analysis
UE6020 Grade (CVD Coated Carbide): The UE6020 grade features a thick TiCN + Al2O3 + TiN coating. This multi-layer CVD coating provides exceptional heat resistance and prevents plastic deformation of the cutting edge. It is specifically optimized for ISO P20-P35 steel machining, offering a stable tool life across a wide range of cutting speeds.
0.2mm Precision Radius: The sharp 0.2mm corner radius is designed for Micro-Boring and fine finishing. It minimizes radial cutting forces, which prevents tool deflection in small-diameter boring bars, ensuring your holes stay perfectly concentric.
Metric vs. Imperial Comparison
| System | Model Designation | I.C. (Inscribed Circle) | Thickness | Radius (RE) |
|---|---|---|---|---|
| Metric | CCMT060202 | 6.35 mm | 2.38 mm | 0.20 mm |
| Imperial | CCMT21.50.5 | 1/4" | 3/32" | 0.0079" |
Recommended Cutting Parameters
*The 0.2mm radius requires lower feed rates to avoid edge breakage. Use with coolant for maximum tool life in UE6020.
| Material Group | Speed (Vc) | Feed (fn) | Depth (Ap) |
|---|---|---|---|
| Carbon Steel (S45C) | 120 - 280 m/min | 0.03 - 0.10 mm/r | 0.10 - 1.00 mm |
| Alloy Steel (4140) | 100 - 220 m/min | 0.03 - 0.08 mm/r | 0.10 - 0.80 mm |
Required Tool Holder
Optimized for use with SCLCR/L 06 Boring Bars and External Holders:
Shop SCLCR 06 HoldersGrade Comparison: UE6020 vs NX2525
UE6020 (Carbide): Choose this for General Purpose & Productivity. It handles variations in material and light interruptions better than cermet. It is the "workhorse" for steel turning.
NX2525 (Cermet): Choose this only for High-Gloss Finishing. Cermet provides a better surface finish (mirror look) but is more brittle and cannot handle the same depth of cut as UE6020.

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.
