Assembly work performed during the installation of metal structures constantly requires drilling holes. However, the use of high strength alloys makes this operation difficult, and sometimes makes it unfeasible with conventional drills. To overcome such difficulties, metal drills HSS-Co which are made of high speed steels with a specific cobalt content.
Scope of Application of HSS-Co Cobalt Drills
Due to its high strength, this high speed tool is widely used in the following cases:
1) creating holes in alloyed alloys;
2) work with ductile corrosion-resistant steel;
3) for the production of blanks using drilling machines;
4) drilling of gray cast irons and heat-acid-resistant steels;
5) if it is necessary to use heat- and wear-resistant drills;
6) drilling any form of steel casting;
7) for fast and accurate hole making;
8) work in extreme conditions;
9) for manual and automated process.
Due to the high reliability of cobalt alloy, HSS-Co metal drills are successfully used in all types of construction, installation and commissioning works, as well as in any repair and technical area.
Technical features of cobalt metal drills
The main characteristic that gives this tool its unique properties is the presence of cobalt (Co) in the alloy (the letter K is used in the Russian marking). Depending on the specific model, the concentration of this element may vary slightly. The most common specimens are those with a Co content in the range of 5 ... 8%. This concentration is sufficient to work with most extra strong metals.
There are two types of cobalt drills:
- standard (for professional drilling of holes);
- a kind of Topline (for higher highly specialized requirements).
These drills can be ordinary and double-sided. In this case, the diameter of the tail section is similar to the diameter of the hole for which the drill is intended.
Key Benefits of HSS-Co Cobalt Drills
The main advantages of such a tool is the ability to work with durable metal structures. In addition, two cutting edges ensure maximum hole precision and process speed. Other benefits include:
- resistance to wear and deformation;
- increased tool hardness;
- no need for frequent sharpening of cutting edges;
- the ability to use in any drilling tool;
- high speed
