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.
