It is here that the name "Cobalt Drill" comes as an unrivaled hero. But the bigger challenge is to find and buy the original cobalt drill in Tehran ; A market that is unfortunately full of counterfeit and low -quality goods.

What is a Cobalt drill and why is it superior to ordinary steel (HSS)?

To understand the value of a original cobalt drill , we first need to know its fundamental difference with standard HSS (High-Speed Steel).

HSS drill: These drills are made of harsh steel and are suitable for softer metals such as iron, aluminum and construction steels. They do well, but with the increase in temperature (which is inevitable in hard metal drilling), they lose hardness and slow down or "burnt".
Cobalt drill (HSS-CO): These drills are a completely different tool. Cobalt here is not a coating or cover; Rather, it is an alloy element that melts with steel. This process substantially changes the molecular structure of the steel. The addition of cobalt (usually 5% or 8%) greatly increases heat resistance. This feature, which is called "Red-Hardness", allows the drill to retain its winning edge even at very high temperatures.

In short, a original cobalt drill is designed to battle the most difficult metals; Where ordinary drills simply disappear.

Difference of Original Cobalt Drill: How to cheat in Tehran Market?

This is the most important part for any buyer. Unfortunately, many sellers sell ordinary HSS drills that only have a golden or bronze color cover instead of original cobalt drill . To avoid this costly mistake, pay attention to these golden points:

Drilling: Original cobalt drills are usually a bronze or matte gold -plated color due to the presence of cobalt alloy. This color is part of the metal itself and is not a coating. If the gold drill has a very shiny and bright similar to the titanium drill, check it more cautiously.

Amers on the Body (Markings): This is a key sign. Authentic manufacturers engrave important information on the drill body. Look for symptoms such as HSS-CO , co 5%, m35 , CO 8% or m42 . These engravings are usually laser and very clean and accurate. Fake drills either lack these engravings or the writings engraved on them are of poor quality, tilted and unreadable.

Irregular Price: Remember, cobalt is an expensive metal. If the proposed price for a original cobalt drill in Tehran was suspiciously low and close to the price of an ordinary HSS drill, it is almost certainly that it is a fake product. No cheapness is inappropriate.

Practical test (if possible): The best test is performance. A real cobalt drill should be able to pierce stainless steel sheets easily and without the need for too much pressure. The fake drill is quickly smoke and the edge disappears.

Buying from a valid source: The simplest and most reliable way to guarantee the purchase Original Cobalt drill in Tehran is to refer to a reputable and reputable seller such as Aras Tool .
