Solid Carbide Drills for HRc42 Steel Power Drilling
Feature Advantage:
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.
