You have probably heard that solid carbide drill bits are the most efficient, and cobalt drill bits are durable. This simple explanation is not enough to make an informative decision on which one to buy. SCTools is committed to helping you machine better, and we will give you a detailed breakdown of these two drill bits and help you choose the ideal one for your machining needs.

Most commonly used methods are sputtering and cathodic arc. In sputtering, the vapor is formed by a metal target being bombarded with energetic gas ions. Cathodic arc method uses repetitive vacuum arc discharges to strike the metal target and to evaporate the material.

The Ionbond™ PVD process is used for the deposition of coatings made of nitrides, carbides and carbonitrides of Ti, Cr, Zr and alloys like AlCr, AlTi, TiSi on a large range of tools and components. Applications include cutting and forming tools, mechanical components, medical devices and products that benefit from the hard and decorative features of the coatings. The typical process temperature for PVD coatings is between 250 and 450 °C. In some cases, Ionbond™ PVD coatings can be deposited at temperatures below 70 °C or up to 600 °C, depending on substrate materials and expected behavior in the application.

SCTools recommends carbide bits as the ideal drill bit to give your manufacturing company the cutting edge it needs to offer an impressive finish to products. You are assured of a masterful and splendid finish with a carbide drill bit that increases production speed and reduces costs.

Carbide drill bits are made of tungsten carbide, a combination of carbon and tungsten. This mixture helps increase metal cutting speeds and feeds, giving it a durable tool for cutting edges. Solid carbide drills are efficient in high-speed drilling and are used on fiber-glass reinforced plastics and hard, non-ferrous heavy metals.

Cobalt drill bits are primarily made from a 5–8% cobalt concentration and high-speed steel. This combination improves the heat and wear resistance of the drill bit, making it durable. Cobalt is added to the stainless steel alloy (Iron and Carbon) during formation, enabling resharpening without losing the drill bit’s cutting quality. Cobalt drill bits are best used on tool steel, stainless steel, and other hard ferrous metals.

Carbide and cobalt drill bits have an ultimate breaking point that can lead to chipping and ineffective functioning if not used properly. Overall, both drill bits get the work done with minimal cons, as shown in the table below.

The coatings can be deposited as mono-, multi- and graded layers. The latest generation films are nano-structured and superlattice variations of multi-layered coatings, which provide enhanced properties. The coating structure can be tuned to producing the desired properties in terms of hardness, adhesion, friction etc. The final coating choice is determined by the demands of the application. The coating thickness ranges from 2 to 5 µm, but can be as thin as a few hundred nanometers or as thick as 15 or more µm. Substrate materials include steels, non-ferrous metals, tungsten carbides as well as pre-plated plastics. The suitability of the substrate material for PVD coating is limited only by its stability at the deposition temperature and electrical conductivity.

PVD coatings reduce long term costs and increase efficiency. Costs are reduced due to longer-lasting tools and increased cutting speeds and feeds, which results in higher productivity. PVD coated tools can be run with dry or with minimum lubrication (or release agents in the case of forming tools) saving both operating and recycling costs. PVD coatings on mechanicals reduce friction and wear and improve performance and reliability.

The PVD,coating process, is a line of sight process which requires substrates to be rotated in the chamber (from single to triple rotation) in order to achieve the required homogeneous coverage and thickness. Coating of inner diameters in PVD is restricted to a depth equal to the diameter of the opening.

Typical lead times are 3 to 5 days. Test parts and samplings take more time as fixturing and process design is required.

High-speed steel drill bits are sometimes ineffective at drilling tough metal to produce spectacular results. To keep your manufacturing company at the top, you need to acquire durable and efficient drill bits, such as carbide or cobalt, to work on tough materials.

Prior to coating, substrates (tools and components) need to be free of any foreign matter, oils and grease on the surfaces that are to be coated, but also in all other areas. The cleaning process is an essential element that determines the adhesion and thus influences the performance of the coated part or tool. All parts are cleaned by Ionbond prior to coating, using a designated process. Ionbond encourages customers to discuss the optimum requirements for their substrates in order to ensure top performance.

As we have seen, both drill bits are made from high-grade materials and perform well. But in terms of strength, solid carbide drill bits are superior, with a hardness of 75 HRC and cobalt’s hardness of 65 HRC on a Rockwell scale. The table below compares the pros of cobalt and carbide drill bits.

Carbide is the hardest and most brittle drill bit in use today and gives a magnificent finish. Carbide drill bits are not suitable for hand tools such as impact drills or cordless drills but are generally ideal for high-production drilling.

PVD is a method for producing metal-based hard coatings by means of generation of partially ionized metal vapor, its reaction with certain gases and by forming a thin film with a specified composition on the substrate.
