Advantages of 4F single tip;

1. The 2-sided main cutting edge of the center positioning tip is formed by CNC one-time machining to ensure that the beating of the main cutting edge and the center positioning tip are on the axis line.

2. The main cutting edge has a transverse front angle to make the cutting more light.

3. Add 2 auxiliary spiral grooves to make them better and less prone to burning

4. The outer circle of the steel body working part is enlarged to make its overall strength better.

Rotational speed: 4500-8000(r/min)

Maximum drilling depth: 57 length depth 20mm, 70 length depth 33mm
