Audited Supplier Description:
1. Quick drilling after opening the blade. CNC precision grinding double back Angle, effectively improve chip removal performance,
make cutting more sharp, drilling speed is also faster.
2. M35 high speed steel was used for milling and forming, and the whole was subjected to vacuum heat treatment.
3. The enemy of stainless steel.
4. Chamfering of round handle. Clear size of stencils, easy to use when identifying bit diameter.
Selling point:
1. The precision grinding process has strong toughness. WEIX twist drill is made of hard and sharp HSS high speed steel after high
temperature quenching and dozens of fine grinding processes. The grinding bit is superior to the rolling bit in both accuracy and
life, especially in improving its toughness.
2. Cobalt-containing twist bit has special sharpening tool, high hardness, and excellent machining performance when drilling
workpiece materials.
3. The drill body is roasted yellow, with higher wear resistance and lower friction coefficient.
4. It can improve the productivity and reduce the processing cost per unit hole.
