The cobalt drill structure is such that the cobalt is combined directly with the HSS steel, not just a layer on the drill. This makes it much more durable than ordinary drills or even coated drills.
Cobalt drill applications
The biggest strength of the cobalt drill is its widespread use in metal drilling. These drills are used in the following:
1. Hard steel drilling (stainless steel/stainless steel, cast iron, titanium)
2. Creating holes in special alloy metals such as vanadium, nickel, hard copper and steel spring $@|
The features and benefits of the cobalt drill
High thermal resistance: The most important feature of cobalt drill is tolerate very high temperatures during drilling; Therefore, when cutting hard metals, he or she is minimized and does not suffer from abrasion or slow. longer Life: than conventional drills or simple HSS, cobalt drills are several times more likely and need to be replaced later. precise performance: Due to the high hardness and stability of the structure, these drills create precision holes with the least twist and error. less need for lubricants: Due to extreme heat tolerance, even in some cases without the use of oil or cooling liquid, but the use of lubricants is still recommended.
Important Tips When using Cobalt Drill
1. Always use lubricant or cooling oil to extend the life of the drill.band@|%and the appropriate pressure of the device to fit both the drill and get a more accurate hole.
Summary Cobalt drill is a specialized tool for drilling hard, durable and alloy metals made with a combination of cobalt and steel steel and has a very high life and performance. Buying this type of drill for those who work with hard metals will be a professional and economical choice.
