Screwdriver Bit Coating | Types of Bit Coatings

It is not a whim that there are different qualities and coatings of tips. Knowing the applications and adapting the quality of the tips to each of them is essential to achieve optimal performance in their use. With different qualities of steel and types of coating on the market, the most common in the tool world are chrome-vanadium alloy steels, chrome, molybdenum and vanadium steels among the raw materials, and TiN (titanium nitride) coating among the surface treatments, although there is a wide variety of them depending on the characteristics that are desired to be obtained from them.

Bianditz bits are made from what is colloquially called molybdenum-vanadium steel. Why? Because of the optimal combination of hardness and resilience that is obtained by applying the appropriate heat treatment. Starting from this good base, the variety of ranges shown in the catalogue are built.

Extra Tips – Molybdenum Vanadium

The extra-hard series bits are designed and manufactured for intensive, high-performance professional use. As we have already mentioned, Bianditz bits are made of steel with Molybdenum and Vanadium alloys and are extremely robust and combine fundamental aspects of hardness 60-62 HRC and toughness. These attributes allow the Bianditz extra-hard series bits a very high level of wear resistance, increasing their productivity, increasing their useful life and therefore reducing the cost of the investment made.

TiN CVD (Titanium Nitride) tips

TiN coating, also known as Titanium Nitride, is a coating that has a very low reactivity towards ferrous metals, thanks to this characteristic the wear of the tip is reduced. We can distinguish this coating from others thanks to its golden colour. It should be mentioned that this type of coating is frequently used in the food industry, in medical applications or in decoration applications. The Bianditz TiN series of tips with Titanium Nitride coating are specifically designed for intensive work, where work is carried out under controlled conditions of perpendicularity and controlled tightening torque. This titanium nitride layer is 3 +/- microns at a hardness of 2,400/2,600 HV (Vickers scale) with the core of the tool being hardened by a procedure similar to the extra-hard tips. This coating provides a 3-4 times longer life in wear resistance and a surface roughness that minimises the ejection effect in the screwdriver.

TiCN (Titanium Carbonitride) Tips

Titanium carbonitride is a ceramic coating applied by PVD technology. The TiCN coating stands out for its high hardness, high adhesion resistance, good wear resistance, improved toughness, low coefficient of friction and high thermal conductivity. Its extraordinary hardness and resistance combined with the torques of the Extra quality tips, provide the tip with a toughness with highly professional results. The TiCN surface coating is grey and is applied only to the work area where the greatest friction and abrasion stresses occur, in this way the rest of the body maintains the optimal torsion characteristics of the Extra quality tips. Hardness 2,500 HV in 2 microns thickness. Suitable for use in assembly lines with controlled tightening torque and good perpendicularity, even for already automated applications.
