When the hardness of the material to be processed is ≥HRC42, the conventional process is difficult to directly process with the drill bit, and must be completed by rough machining + heat treatment + finishing process. This processing process is complicated, the time is long and the cost is high.
The powerful drill bit can realize the material drilling of ≥HRC42, especially after the quenching.
Achieve the completion of rough and fine drilling, greatly improve processing efficiency, ensure product quality, and have high cost performance.
The unique coating post-treatment technology effectively reduces the cutting force, making the chip removal smoother and safer.

Technical Information:

Typical application of integral alloy drill bits:
- Small diameter hole
- Tight or precision tolerance hole
- The hole shorter than a deep hole
Chip formation and chip evacuation are important issues in drilling. It depends on the workpiece material, blade geometry selection, coolant pressure, capacity, and cutting parameters.
Chip clogging can cause the drill bit to move radially and affect hole quality, bit life and reliability.
The drill bit is mounted on the shank chuck and its circumferential runout must be less than 0.02 mm.
