| Tool | Damage Form | Cause | Countermeasure |
| Flank Wear | | · Tool grade is too soft. · Cutting speed is too high. · Flank angle is too small. · Feed rate is extremely low. | · Tool grade with high wear resistance. · Lower cutting speed. · Increase flank angle. · Increase feed rate. |
| Crater Wear | | · Tool grade is too soft. · Cutting speed is too high. · Feed rate is too high. | · Tool grade with high wear resistance. · Lower cutting speed. · Lower feed rate. |
| Chipping | | · Tool grade is too hard. · Feed rate is too high. · Lack of cutting edge strength. · Lack of shank or holder rigidity. | · Tool grade with high toughness. · Lower feed rate. · Increase honing. (Round honing is to be changed to chamfer honing.) · Use large shank size. |
| Fracture | | · Tool grade is too hard. · Feed rate is too high. · Lack of cutting edge strength. · Lack of shank or holder rigidity. | · Tool grade with high toughness. · Lower feed rate. · Increase honing. (Round honing is to be changed to chamfer honing.) · Use large shank size. |
| Plastic Deformation | | · Tool grade is too soft. · Cutting speed is too high. · Depth of cut and feed rate are too large. · Cutting temperature is high. | · Tool grade with high wear resistance. · Lower cutting speed. · Decrease depth of cut and feed rate. · Tool grade with high thermal conductivity. |
| Welding | | · Cutting speed is low. · Poor sharpness. · Unsuitable grade. | · Increase cutting speed. (For ANSI 1045, cutting speed 260 SFM.) · Increase rake angle. · Tool grade with low affinity. (Coated grade, cermet grade) |
| Thermal Cracks | | · Expansion or shrinkage due to cutting heat. · Tool grade is too hard. Especially in milling. | · Dry cutting. (For wet cutting, flood work material with cutting fluid) · Tool grade with high toughness. |
| Notching | | · Hard surfaces such as uncut surface, chilled parts and machining hardened layer. · Friction caused by jagged shaped chips. (Caused by small vibration) | · Tool grade with high wear resistance. · Increase rake angle to improve sharpness. |
| Flaking | | · Cutting edge welding and adhesion. · Poor chip disposal. | · Increase rake angle to improve sharpness. · Enlarge chip pocket. |
