Drill/mills are versatile cutting tools that combine some of the capabilities of drill bits and end mills, making them useful for a variety of machining tasks. They are characterized by their pointed tip, which can be used for drilling operations, and flutes that can also perform milling actions. Here are some of the primary uses and advantages of drill/mills:

**Drilling Operations**: Drill/mills can be used to drill holes in a workpiece, similar to standard drill bits. Their pointed tip allows them to start the hole accurately. Due to their lack of a radial cylindrical margin (like a dedicated drill bit) they are not optimal for high production applications or for applications that need superior finishes.

**Milling Operations**: They can perform light milling tasks, such as slotting, side milling, and contouring. This is facilitated by the cutting flutes along the sides of the tool.

**Chamfering**: The angled tip of a drill/mill makes it suitable for chamfering or beveling the edges of a workpiece. This is useful for removing sharp edges and preparing parts for fitting or welding.

 **Plunging**: Unlike some traditional end mills that cannot plunge (move vertically into the material) due to their design, drill/mills can plunge into a workpiece to start a hole or cavity.

 **Engraving**: In some applications, especially with CNC machines, drill/mills can be used for engraving or detailing on the surface of materials due to their pointed tip.


**Versatility**: Drill/mills reduce the need for tool changes between drilling, milling, and other operations, which can save time and increase efficiency in the workshop.

**Cost-effectiveness**: By combining functions, they can reduce the number of tools that need to be purchased and maintained.

**Space-saving**: In environments where space or tool storage is limited, having tools that can perform multiple functions is highly beneficial.

 However, it’s important to note that while drill/mills offer versatility, they may not always be the best choice for all applications. Dedicated drill bits or end mills might perform specific tasks more efficiently or with higher precision in certain materials or situations. The choice of whether to use a drill/mill or a more specialized tool will depend on the specific requirements of the task at hand, including the material being worked on, the precision required, and the equipment available.

AlTiN coating improves the performance and lifespan of a cutting tool. It is a thin layer of aluminum titanium nitride that is applied to the surface of the tool, providing improved hardness, wear resistance, and lubricity. The coating can also reduce friction between the cutting tool and the material being cut, resulting in better cutting speeds and reduced heat buildup. Overall, AlTiN coating can enhance the efficiency and precision of cutting tools, making them more effective for a wide range of applications.
