Why TiN coated drills?

What are TiN drill bits used for?

TiN is a ceramic material that increases the surface hardness of the bit and provides a thermal barrier by reducing friction. This results in increased production rates, corrosion resistance, and 3 to 6 times longer tool life. Titanium bits are suitable for drilling iron, steel, aluminum, magnesium, and wood.

Why TiN coating is useful?

The advantages of TiN coating include high hardness and adhesion, good ductility, excellent lubricity, high chemical stability and tough resistance to wear, corrosion and temperature.

Why are drill bits coated?

This coating helps reduce friction in the cut, reducing heat buildup in the drill bit, as well as improving the flow of material out of the drilling point. It also delivers protection against corrosion, rust and water damage.

What is the best coating for a drill bit?

A titanium nitride, sometimes called TiN, coating reduces friction during drilling and increases heat resistance. Coating a drill bit with titanium nitride can increase the life of the bit up to 5 times. It also allows for faster drilling speeds.

What does TiN coated mean?

Tinning is the process of thinly coating sheets of wrought iron or steel with tin, and the resulting product is known as tinplate. The term is also widely used for the different process of coating a metal with solder before soldering.

Is TiN coating good for aluminum?

The titanium nitride (TiN) coatings deposited by physical vapor deposition (PVD) are extensively used on aluminum due to their excellent surface features.

What is the hardest drill bit for metal?

Cobalt (HSCO) includes between 5 and 8% cobalt in the base, making it an excellent option for drilling into harder steel and stainless steel. Carbide is the strongest drill bit for metal and is typically reserved for professional-grade tools.

What is titanium nitride used for?

Titanium nitride (TiN) is an extremely hard material that is used as coating material for various tools and implants (TiN coating). It is also used in plastics such as PET flasks to improve the physical properties of these flasks and to improve the efficiency of PET manufacturing processes.

What is tungsten carbide bits used for?

Many tools for cutting, shaping, drilling and sharpening are now made using Tungsten Carbide for uses in Jewellery Making, Stone Carving, Glass Art and Wood Carving because of it’s extreme hardness, toughness and durability.

What is the advantage to a tungsten carbide bit?

Though drill bits come in standard sizes, tungsten drill bits are one of the more durable styles because of the material’s toughness. One of the main benefits of tungsten carbide drill bits is its hardness. Tungsten falls between 8.5 and 9 on Moh’s hardness scale (trailing diamonds, which have a hardness of 10).
