5.【Five Edge Design】With five cutting edges, it can achieve the effect of rapid chip removal and heat dissipation, realizing fast drilling;
6.【Surface plating treatment】HSS material is surface plated with Titanium Aluminum Nitride (TIALN) to improve cutting performance, increase hardness, wear-resistant and durable, corrosion-resistant;
7.【Applicable Machines】Quick-change shank, suitable for most power tools, such as hand drills, electric drills and bench drills.
Precautions:
1. Applicable to hand electric drill, bench drill; hand electric drill use should pay attention to the operating techniques, vertical drilling, do not swing from side to side. Drill feed speed should not be too fast, do not press hard / brute force operation, in order to avoid breaking.
2. Continuous drilling is recommended to use cutting oil or water cooling can greatly extend the service life;
3. ONLY choose flat drilling mode! DO NOT use the impact and hammering mode!
