Blanks: Cutting and Cutting Tools
Each machining process uses a specialized cutting tool. There are two basic types of these tools. The first ones are point tools which are used for , planing and boring processes, and the second ones are tools which are used for and drilling. Cutting tools are usually made from and high-speed steel. Upkeep of cutting tools can be very expensive, but it is important for the tools to stay in good condition, so the work-piece is cut correctly.
To finish the work-piece, we usually perform multiple . The whole process can be divided into two sections: the phase and the phase. cuts are used to change the form of the material according to the desired shape of the final product. The last cut is called the cut which is used to finish the surface of the work-piece while it gains the exact desired dimensions. Sometimes it might be necessary to use cutting which lubricates and cools the cutting tool.

Blanks: Drilling
Drilling employs a tool called a drill and is conducted on a machine. The rotates in order to drill through the used work-piece. The drill has a shape which helps eliminate . If we widen an already made hole, the process is called (similarly to internal turning). We can use a tool called holesaw if the hole has a large . Holesaw has a cylindrical shape with teeth. We are able to drill into concrete with the use of holesaws whose edges are made of industrial . This process is called drilling or diamond drilling. Drilling can be automated by CNC.
There are various drill which can be used if needed, such as peck drills, spotting drills or chucking . Peck drill bits are used when we frequently retract the bit back in order to lower of the drilling. Spotting drill bits are used to drill shallow holes. Chucking are used for with exceptional precision and accuracy.

Blanks: Milling
Milling employs rotating cutters which are typically stationary. The cutters are toothed disc-like tools. The used work-piece is fixed onto a which is part of a milling machine. The of the milling machine is then moved against the of the cutters, so the material is cut by them. For milling is typical to move the material in the of the cutter rotation.
Milling can be divided into two categories. The first one is milling which we use to cut surfaces or cavities with bottom into the material. The second one is milling which is used when gear teeth, deep slots or are required to be made.
The milling machine is able to perform various other processes such as , routing, die-sinking, etc. Most milling machines have either vertically or horizontally mounted with the exception of milling machines which can have both.
