Solid Carbide Drills with Double Edged Belt for 8D Deep Hole Drilling

Feature Advantage:

This series of solid carbide drills is extremely versatile, and the same series can achieve efficient drilling of steel, stainless steel, cast iron and other materials.
Optimized drill tip structure for better cutting performance.
Double-edged belt design for improved drilling stability.
∅2 - ∅25 Diameter, 0.1 mm first gear, complete types.
3D, 5D, 8D, all kinds of lengths are complete.
All specifications and models are available in both internal and external cooling to meet the requirements of various machine tools.
AlCrN coating combines excellent wear resistance with anti-blocking properties for improved edge stability.
The unique coating post-treatment technology effectively reduces the cutting force, making the chip removal smoother and safer.

Technical Information:

Typical application of solid carbide drills:
- 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, tool geometry selection, coolant pressure, capacity, and cutting parameters.
Chip clogging can cause the drill to move radially and affect hole quality, tool life and reliability.
The drill 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, Internally cooled drills can be increased by 10%-15% depending on the situation.
