7 Types of 4 Flute Milling Cutter That Pros Use

Milling cutters are used to shape and form metal, wood, or other machinable materials. A 4 flute milling cutter is a specific type of cutting tool used for machining operations such as drilling, slotting, and side milling. In this guide, we will explore the different styles of 4 flute milling cutters available and explain how to pick the right one for your job.

Convex – for general purpose cutting, used mainly for high speed machining.

Convex 4 flute milling cutters are designed to reduce material from the workpiece quickly. This type of cutter is best suited for high speed machining operations such as drilling. The design makes it easier for chips to flow out and away from the cutter, which improves cutting performance. They come in various sizes and shapes depending on your project needs, so make sure you choose the right one for your job!

Corner Radiused – with radiused corner that allows it to produce deeper cuts than the Convex cutter with less damage to cutting edges.

Corner Radiused 4 flute milling cutters are great when you need to make deep cuts in harder materials. These cutters have radiused corners that will produce a more even finish, allowing for deeper cutting without excessive damage to the cutting edges. They come in a variety of sizes and shapes, making them highly versatile and perfect for any job.

End Mill – a strong and versatile cutter suitable for use with a variety of materials, including aluminum and wood.  

The end mill 4 flute milling cutter is designed to produce clean cuts in a variety of materials and thicknesses, making them highly versatile. These cutters use four cutting edges to shear the material during the cutting process, allowing them to create accurate cuts with minimal chatter. They come in different sizes so you can pick the perfect one for your project, allowing you to achieve a superior finish on all types of projects.

Double End Mill – designed to be used when two different kinds of material (such as aluminum and stainless steel) are being cut at the same time.

Double end mills are designed to be used when two different kinds of material (such as aluminum and stainless steel) are being cut at the same time. Each flute is ground with a different pitch, allowing it to cut two materials in one pass, reducing your cutting time significantly. Double end mills are mainly used for creating slots and recesses, but they can also be used for other applications that benefit from having two cutting edges on each tool.

Hollow Mills – intended for working in tight places or machining structurally difficult shapes; has many flutes around its circumference; also known as TREs (taper relief end mills).  

Hollow mills are specifically designed for working in tight places or machining structurally difficult shapes. Unlike other flute milling cutter, hollow mills have many flutes around their circumference making them well-suited for cutting irregularly shaped material. It also helps reduce vibration when plunging, allowing you to achieve better surface finishes on your work. Hollow mills, also known as TREs (taper relief end mills), are an excellent choice when machining hard metals or deep cavities.
