Solid Carbide Drills for Drilling and Milling Thread Compound
Drilling
Feature Advantage:
- Efficient cutting: threaded bottom hole, hole chamfering and thread milling with one knife.
- High precision and long life: the thread is bright, the accuracy
level is adjustable, the coaxiality is high, and the service life
is up to 200m.
- Unique structure: unique internal cooling structure, central internal cooling plus blade partial flow.
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.
