√FEATURE:
The drill bit is made of M2 high-speed steel material, which has high hardness and wear resistance, making it suitable for processing medium-high hardness materials
Uncoated (Bright) surface is smoother, which reduces friction resistance during drilling
The 118° tip angle is a sharper tip angle, the cutting edge is sharper, and the resistance when cutting into the material is small.

√APPLICATION:
The drills are suitable for hard metals, such as steel, alloy cast iron, stainless steel, iron, copper, aluminum alloy, and cast iron. They are also effective in plastics and wood.

√NOTE:
When machining different materials, the spindle speed and feed rate vary.
Generally, the harder the material, the lower the spindle speed and feed rate need to be.
Position the twist drill at 90° to the workpiece.
For thick materials, drill in multiple passes to prevent overheating or breakage.
For large holes, start with a guide hole.
Use cutting fluid to improve efficiency, extend tool life, and reduce material damage.
For specific speed and feed rates recommended for common materials, please refer to the details provided on the product page.
