Drill America 12 Half Round Bastard File, DIC Series

The half round files are a versatile tool that can be used on a variety of surfaces, including concave, convex, and flat. Regardless of the file type, there are some consistent features that are worth noting.

Firstly, the files are rounded on one side and flat on the other, allowing them to be used effectively on both curved and flat surfaces. This design provides the user with greater flexibility and the ability to tackle a wider range of tasks.

When it comes to the cutting pattern on the backs of the files, there are some variations depending on the specific file type. The backs of all half round bastard files are double cut, meaning they have a more aggressive cutting pattern that is well-suited for removing material quickly. In contrast, the backs of all half round second cut files longer than 6 inches are double cut, while the 4 and 6 inch files are single cut, which results in a slightly finer finish.

The half round smooth files, on the other hand, have a single cut pattern on the backs, providing a smoother and more refined finish. This makes them well-suited for tasks that require a higher level of precision and attention to detail.

Interestingly, the flat sides of all half files are also double cut, regardless of the file type. This ensures a consistent and efficient cutting performance on flat surfaces, complementing the versatility of the half round design.

In summary, the half round files are a versatile and well-designed tool that can be used on a wide range of surfaces, from concave and convex to flat. The cutting patterns on the backs and sides of the files are tailored to provide the best possible performance for specific tasks, making them a valuable addition to any workshop or toolbox.
