- Forged drill body with special surface treatment enhances wear resistance and durability
Special Drill Coating PC5335
High toughness ultra-fine substrate provides excellent machining stability
High lubricity coating suppresses built-up edge formation, improving cutting performance
Optimal universal material for various drilling applications
High lubricity coating with good welding performance
Combination of high hardness and high toughness layers achieves balance between wear resistance and chipping resistance
Optimized high toughness substrate provides excellent fracture resistance and cutting stability during drilling
* Proprietary PVD coating KROEX - TechTM substrate is more suitable for hole machining
Drilling Precautions
- If the hole diameter is larger than the center drill diameter, or if there are protruding parts, severe vibration may cause damage to the center drill and inserts
- If there is an inclined surface, ensure it is leveled through facing operations before drilling
- Stacked plate machining is not supported
