Description:
This drill has a unique stepped structure, which enables it to flexibly open holes of various sizes, thus achieving the convenience of one drill to meet multiple needs. Compared with traditional twist drills, it can be constructed without the use of center impact, which greatly reduces the risk of breakage, and can be applied to drilling needs of various specifications, simplifying the operation steps.
This drill can not only open holes, but also remove burrs, chamfer, open holes and expand holes, which are not easily achieved by traditional twist drills. Compared with ordinary twist drills, it shakes less during operation, and can open precise and beautiful holes even without center impact.
When using, it can be used with a hand drill or a bench drill, and it is recommended to use water for cooling, which can not only effectively extend the service life of the drill bit, but also reduce the high temperature generated during drilling and reduce tempering. It is particularly important to note that when drilling stainless steel, be sure to choose M35 material and avoid using 4241 material to avoid scrapping the drill bit. For drilling holes in steel plates below 5 mm, water cooling measures should be strengthened, because such working conditions will more easily cause the drill bit to heat up during use and quickly become scrapped.
Overall, this drill bit provides an efficient, safe and economical solution for field work through its advanced design and multifunctional nature, and is particularly suitable for professional environments that require frequent drilling operations.
