When selecting drilling inserts, there are a few key factors to consider. Firstly, the material of the insert should be chosen based on what type of material is being drilled. Different materials require different grades of inserts. For example, harder materials such as stainless steel require a higher grade of insert than softer materials such as aluminum. Secondly, the geometry of the insert should be chosen based on the type of hole being drilled. Different geometries will produce different types of holes, such as straight, taper, or curved. Thirdly, the coating of the insert should be chosen based on the cutting speed and temperatures that it will be exposed to. Different coatings can increase the cutting speed and reduce the heat generated when drilling. Lastly, the size of the insert should be chosen based on the size of the hole being drilled.
Taking these factors into account when selecting drilling inserts will ensure that the job is done properly and efficiently. By selecting the right material, geometry, coating, and size, the drilling process will go more smoothly and the finished product will be of higher quality.
