Feature Advantage:

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.
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.
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.
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.
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.
