Frequently Asked Questions (FAQs)

1. What are drill mills for?

Drill mills are versatile tools used for chamfering, milling, and drilling non-ferrous materials. They are also suitable for light-duty spotting operations. However, it is important to note that drilling and spotting operations are recommended only for drill mills with an included angle greater than 60°.

2. What is the difference between a drill mill and a drill bit?

The main difference between a drill mill and a drill bit is their function. A drill bit is designed for boring straight down into materials like metal, plastic, or wood, while a drill mill is designed for sideways cutting. They serve different purposes and cannot be interchanged.

3. Can a drill be used as a mill?

Using a drill as a mill is possible but with limitations. It can be used for very light milling, such as cutting through plastic. However, it is not recommended for heavy milling operations as it can cause damage to the drill press due to the lack of rigidity and stability.

4. What can you use a drilling machine for?

A drilling machine is primarily used for drilling holes in hard materials. It is widely used in various industries such as manufacturing, metallurgy, woodworking, masonry, and construction. Additionally, drilling machines can also be used for tasks like tapping, spot facing, reaming, counter sinking, and counter boring.

5. Can you mill with a drill chuck?

Milling with a drill chuck is possible but with limitations. It can work for light milling if the drill chuck is securely held into a milling machine spindle with a drawbar. However, the reduced rigidity of the setup may affect the finish and precision of the milling operation.

6. Why is milling better than drilling?

Milling is often considered better than drilling because a milling machine can operate in three directions simultaneously, providing more versatility and precision. In contrast, a drill press only moves up and down in one axis, limiting its capabilities. Additionally, milling machines can achieve higher rotational speeds, allowing for more precise and efficient cutting.
