5 Common Reasons for Early Wear of Carbide Cutting-Tools

Even premium cemented-carbide cutting-tools can wear out prematurely if cutting-parameters or operation settings are incorrect. Here are 5 frequent causes:

1. Excessive cutting speed: Too-high spindle speed creates extreme heat, burning off the tool coating.

2. Improper feed rate: Too-low feed leads to friction-wear on the tool tip.

3. Wrong carbide grade: Using a finishing-grade insert for heavy rough-cutting causes chipping.

4. Insufficient cooling-liquid supply: Poor coolant cannot take away cutting heat quickly.

5. Unstable clamping: Loose tool holders produce vibration and notch wear.

If your carbide inserts wear much faster than expected, check these 5 factors first. Our technical engineers can also help you optimize your cutting-parameters.
