Solid Carbide Drills for Stainless Steel Drilling with 5D
Internal Cooling
The First Choice for Stainless Steel Drilling.
Feature Advantage:
- D3.0-D20.0 diameter
- The length includes 3D and 5D.
- Each model has two types: internal cooling and external cooling.
- The first choice for mild steel and stainless steel drilling.
- The sharp cutting edge avoids the formation of built-up edge and is
suitable for high performance drilling.
- The optimized drill tip structure enhances the strength of the
chisel and inner edges, makes the cutting lighter and the chip
breaking is better.
- Nano-TiAlN coating for excellent wear and high temperature
resistance.
- The unique groove structure has large effective chip space, smooth
chip removal and stable drilling.
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 clogging can cause the drill bit to move radially and affect
hole quality, bit life and reliability.
- 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.
- The drill bit is mounted on the shank chuck and its circumferential
runout must be less than 0.02 mm.
Recommended Cutting Parameters:
- When using this series of tools for the first time, the cutting is
performed according to the recommended cutting speed of 90% or the
feed rate of 85%. When the cutting condition is stable, the cutting
speed and the feed are increased one by one.
- Cutting parameters are recommended for water soluble cutting
fluids.
- Use a defect-free, clean chuck when installing the drill and
control the drill runout to within 0.02 mm.
- The recommended cutting parameters are for applications where the
hole depth is below 5D.
- The recommended cutting parameters are externally cooled drills,
which can be increased by 10%-15% depending on the situation.
