Recommended parameters: speed 2000-3000. For ordinary metals, the thickness should not exceed 2.5mm, and for stainless steel, it should be less than 2.0mm.
Notes: The speed should not be less than 1000. It should not be processed with a hand drill or unstable equipment.
It is recommended to use an extrusion tap for tapping
It only takes a few seconds to make a threaded bushing on the surface of a thin material. No other materials are needed.
A high-precision product can be manufactured in just two steps.
Short drill: used for commonly used thin-walled parts. Suitable for penetrating workpieces with a thickness of 0.8mm~3mm.
The cylindrical part of the drill bit is shorter, and the hole formed after extrusion molding is conical, which can enhance the tapping strength.
Long drill: used for thicker workpieces, or when straight holes need to be processed. Suitable for penetrating workpieces with a thickness greater than 3mm-12mm.
The cylindrical part of the drill bit is longer, and the hole formed after extrusion molding is longer.
