DCMT11T304 HTI10
Uncoated Precision | Non-Ferrous Specialist | High-Mirror Finish
The Edge Sharpness Leader
HTI10 Grade (Uncoated Tungsten Carbide): The HTI10 is a high-hardness, fine-grained uncoated carbide grade. Without the "rounding" effect of CVD or PVD coatings, the HTI10 maintains a razor-sharp edge. It is specifically engineered for non-ferrous materials where chip welding is a risk, providing a mirror-like surface finish on Aluminum alloys, Brass, Bronze, and high-density Plastics.
DCMT Geometry (Free-Cutting): The 55-degree diamond shape with a 7-degree positive relief angle is designed for minimal cutting resistance. This is vital when machining soft materials to prevent the part from deforming or vibrating, especially in thin-walled components.
0.4mm Radius (Precision Profiling): The "04" nose radius allows for intricate detailing and precision finishing. It generates low radial force, ensuring that tolerances remain tight even during high-speed finishing passes on non-ferrous workpieces.
Metric vs. Imperial Comparison
| System | Model Designation | I.C. (Inscribed Circle) | Thickness | Radius (RE) |
|---|---|---|---|---|
| Metric | DCMT11T304 | 9.525 mm | 3.97 mm | 0.40 mm |
| Imperial | DCMT32.51 | 3/8" | 5/32" | 0.0157" (1/64") |
Recommended Cutting Parameters
*HTI10 is uncoated. High cutting speeds with fluid are recommended for Aluminum to ensure mirror finish.
| Workpiece Material | Speed (Vc) | Feed (fn) | Depth (Ap) |
|---|---|---|---|
| Aluminum Alloy (6061/7075) | 300 - 800 m/min | 0.05 - 0.20 mm/r | 0.10 - 2.00 mm |
| Copper / Brass / Bronze | 150 - 400 m/min | 0.05 - 0.15 mm/r | 0.10 - 1.50 mm |

HTI10 (Uncoated Specialist): Superior for Aluminum and Plastics. The lack of coating allows for the sharpest edge possible, preventing "fuzziness" or melting of the material.
VP15TF (PVD Generalist): Use this if you are switching between Steel and Aluminum. While less sharp than HTI10, the coating provides protection if you accidentally cut ferrous metals.
