Endmills for Steel
While you won’t find the best drill bit for aluminium here, these endmills are designed for use with steel. The name endmill is fairly self-explanatory, as endmills are used in milling applications. Some examples of milling applications are reaming, drilling, slotting, contouring, plunging, face milling, and profile milling. Due to this diversity, endmill is an umbrella term that encompasses all manner of tools, such as milling cutters and slot drills. Our endmills are available as square-end, ballnose and corner radius solutions, making them suitable for use in an array of applications.
Slot Drills for Steel
Slot drills (also known as slot mills) are milling cutters that are most often applied to general machinery. As a rule of thumb, these products have two flutes, flat ends, flat edges, and two opposing radial cutting edges. Additionally, slot drills are often equipped with reinforced teeth to contribute to their durability and minimise the likelihood of chipping. Consequently, the tools are very versatile, being suitable for use in engineering, carpentry, construction, metalworking, and woodworking. In addition to the variety of materials they can be used with, slot drills also tend to cut in all directions, allowing for efficient practice.
Thread Mills for Steel
Last but not least is thread mills, which, like endmills, are essentially named after their purpose; thread mills cut threads by milling. In order to thread mill, the diameter of the tool needs to be smaller than the thread diameter, as the tool is straight, and the thread has a helix angle. Consequently, when too big a tool is used, this can lead to the deviation of the thread profile. The entire process of thread milling can be long-winded; however, it’s the best way to achieve a quality thread. Ultimately, when precision is required, thread milling is the way to go.
