CCMT09T304 HTI10
Non-Ferrous Specialist | Sub-Micron Uncoated Carbide | 0.4mm Sharp Radius
Material Science & Razor Edge
HTI10 Grade (Uncoated Precision): Specifically engineered for ISO N (Non-Ferrous Metals). HTI10 is a sub-micron tungsten carbide grade. By remaining uncoated, this insert maintains a significantly sharper cutting edge than PVD/CVD counterparts. This sharpness is critical for preventing material from welding to the tip (Built-Up Edge) when machining soft Aluminum, Copper, or thermoplastics.
0.4mm Radius & Positive Geometry: The 04 (1/64") radius is the precision standard for finishing. Combined with a high positive rake angle, it reduces cutting resistance and heat, allowing for exceptionally high surface speeds and a mirror-like finish on non-ferrous workpieces.
Metric vs. Imperial Comparison
| System | Model Designation | I.C. (Inscribed Circle) | Thickness | Radius (RE) |
|---|---|---|---|---|
| Metric | CCMT09T304 | 9.525 mm | 3.97 mm | 0.40 mm |
| Imperial | CCMT32.51 | 0.375" (3/8") | 0.156" (5/32") | 0.0157" (1/64") |
Recommended Cutting Parameters
*HTI10 thrives at very high surface speeds. Use flood coolant to ensure efficient chip evacuation in Aluminum.
| Workpiece Material | Speed (Vc) | Feed (fn) | Depth (Ap) |
|---|---|---|---|
| Aluminum Alloys | 400 - 1000 m/min | 0.05 - 0.20 mm/r | 0.10 - 2.50 mm |
| Copper / Brass | 200 - 500 m/min | 0.05 - 0.15 mm/r | 0.10 - 1.50 mm |

Shop SCLCR 09 HoldersPro-Tip: HTI10 vs VP15TF
HTI10 (Uncoated): The Specialist for non-ferrous metals. The razor-sharp edge prevents "material smearing." Essential for high-finish aluminum work.
VP15TF (PVD): The Universalist for steel. Never use HTI10 on hard steel; it lacks the thermal coating to protect against carbon-based heat, leading to instant edge failure.
