What is CNC milling?
CNC milling is a manufacturing process that involves the use of computer numerical control (CNC) technology to automate the milling of various materials. Milling is a process of removing material from a workpiece using a rotating cutter to produce a desired shape or surface finish. CNC milling allows for the production of complex and intricate parts with a high level of precision and accuracy.
Tools are a crucial aspect of CNC milling, as they determine the shape and finish of the final product. Choosing the right tool for the job is essential to ensure that the desired results are achieved. In this article, we will provide a list of CNC milling tools and discuss their uses and applications.
End mills
End mills are a type of milling cutter that are used to create shapes and profiles in a workpiece. They are typically made of high-speed steel or carbide and have a pointed tip that rotates at high speeds to remove material from the workpiece.
There are various types of end mills, including square end mills, ball nose end mills, and chamfer end mills. Square end mills have a flat end that is used to create flat-bottomed pockets and slots. Ball nose end mills have a rounded tip that is used to create curved surfaces and contours. Chamfer end mills have a chamfered edge that is used to create angled surfaces and corners.
End mills are commonly used in CNC milling to create a wide range of shapes and profiles, including pockets, slots, and contours. They are versatile tools that are suitable for use on a variety of materials, including metals, plastics, and composites.
Face mills
Slot drills are a type of milling cutter that are used to create slots and holes in a workpiece. They are similar to end mills in that they have a pointed tip that rotates at high speeds to remove material from the workpiece. However, slot drills have a shorter overall length and a larger diameter than end mills, which makes them more suitable for creating deeper slots and holes.
There are various types of slot drills, including single flute slot drills and multi-flute slot drills. Single flute slot drills have a single cutting edge and are used to create clean and precise cuts in materials such as aluminum and brass. Multi-flute slot drills have multiple cutting edges and are used to create faster and rougher cuts in materials such as steel and cast iron.
Slot drills are commonly used in CNC milling to create slots and holes in a workpiece, as well as to create rounded corners and edges. They are suitable for use on a variety of materials and are particularly useful for creating deep and narrow slots and holes.

Drills
Drills are a type of milling cutter that are used to create holes in a workpiece. They have a pointed tip that rotates at high speeds to remove material from the workpiece, and are typically made of high-speed steel or carbide.
There are various types of drills, including twist drills, center drills, spade drills, and taper shank drills. Twist drills have a cylindrical shape and are used to create straight holes in a workpiece. Center drills have a shorter and thicker body than twist drills and are used to create a starting hole for a larger drill. Spade drills have a flat end and are used to create holes in thin materials. Taper shank drills have a tapered end that allows them to be mounted in a drill chuck or holder.
Drills are commonly used in CNC milling to create holes in a workpiece, as well as to create countersinks and counterbores. They are suitable for use on a variety of materials and are particularly useful for creating precise and accurately sized holes.
Reamers
Reamers are a type of milling cutter that are used to finish and size holes in a workpiece. They have a pointed or conical tip that rotates at high speeds to remove material from the inside of a hole, creating a smooth and accurate finish. Reamers are typically made of high-speed steel or carbide and are used to create precise and accurately sized holes.
There are various types of reamers, including chucking reamers and hand reamers. Chucking reamers are designed to be mounted in a chuck or holder and are used to create precise and accurately sized holes in a workpiece. Hand reamers are designed to be used by hand and are used to finish and size holes in a workpiece.
Reamers are commonly used in CNC milling to create precise and accurately sized holes in a workpiece. They are suitable for use on a variety of materials and are particularly useful for creating smooth and accurately sized holes in materials such as metals and plastics.
Taps
Taps are a type of milling cutter that are used to create threads in a workpiece. They have a pointed or conical tip that rotates at high speeds to remove material from the inside of a hole, creating threads on the inside surface of the hole. Taps are typically made of high-speed steel or carbide and are used to create internal threads in a workpiece.
There are various types of taps, including plug taps, taper taps, and bottoming taps. Plug taps have a tapered end and are used to create threads in a hole that is slightly larger than the tap’s major diameter. Taper taps have a longer and more gradual taper than plug taps and are used to create threads in a hole that is slightly smaller than the tap’s major diameter. Bottoming taps have a longer and more gradual taper than taper taps and are used to create threads in a hole that is the same size as the tap’s major diameter.
Taps are commonly used in CNC milling to create internal threads in a workpiece. They are suitable for use on a variety of materials and are particularly useful for creating precise and accurately sized threads in materials such as metals and plastics.
Dies
Dies are a type of milling cutter that are used to create external threads on a workpiece. They have a pointed or conical tip that rotates at high speeds to remove material from the outside surface of a workpiece, creating threads on the outside surface. Dies are typically made of high-speed steel or carbide and are used to create external threads on a workpiece.
There are various types of dies, including round dies and hexagonal dies. Round dies have a cylindrical shape and are used to create external threads on round rods or pipes. Hexagonal dies have a hexagonal shape and are used to create external threads on hexagonal rods or bolts.
Dies are commonly used in CNC milling to create external threads on a workpiece. They are suitable for use on a variety of materials and are particularly useful for creating precise and accurately sized threads in materials such as metals and plastics.
Knurls
Knurls are a type of milling cutter that are used to create a pattern of raised ridges or grooves on a workpiece. They have a pointed or conical tip that rotates at high speeds to remove material from the surface of a workpiece, creating a pattern of raised or indented lines. Knurls are typically made of high-speed steel or carbide and are used to create a decorative or functional pattern on a workpiece.
There are various types of knurls, including straight knurls and diagonal knurls. Straight knurls have a straight pattern of raised or indented lines and are used to create a decorative or functional pattern on a workpiece. Diagonal knurls have a diagonal pattern of raised or indented lines and are used to create a decorative or functional pattern on a workpiece.
