Drilling inserts, also known as drill bushings, are used to guide drill bits when drilling. They are manufactured using a variety of materials, depending on the application and the environment in which they will be used. Commonly used materials for manufacturing drilling inserts include steel, aluminum, tungsten carbide, and polycrystalline diamond.
Steel is the most commonly used material for drilling inserts, due to its strength and durability. It is used in a variety of applications, from general purpose drilling to high-precision drilling. Steel drilling inserts are usually made of high-grade steel, such as AISI 4140 or AISI 8620.
Aluminum is a lightweight material that is often used for drilling inserts in applications where weight is a factor. Aluminum drilling inserts are usually made of 6061 or 7075 aluminum alloy. They are not as strong as steel drilling inserts, but they provide good wear resistance and are corrosion resistant.
Tungsten carbide is a very hard material that is used for drilling inserts in applications that require high wear and abrasion resistance. Tungsten carbide drilling inserts are usually made of a tungsten-cobalt alloy, and they are extremely durable and long-lasting.
Polycrystalline diamond (PCD) is a synthetic material that is used for drilling inserts in applications that require high precision. PCD drilling inserts are usually made of a diamond-tungsten-carbide composite. They are very precise and durable, and they can be used for drilling in hard materials such as stainless steel and titanium.
No matter what material is used for manufacturing drilling inserts, it is important to choose the right material for the application. Different materials offer different benefits, so it is important to consider all the factors before making a decision.
