Have you ever been interested in knowing how a cutting tool company works? 

Have you ever heard of multi-flute end mills that are the backbone of a cutting tool company?  

If not, no worries because in this blog we will share with you, different types of end mills and flutes that collectively make a huge part of the cutting tool company. So, let’s begin reading.  

Types of End Mill 

End grinders are used to create shapes and holes in workpieces in milling, profiling, contouring, slotting, machine building, drilling, and boring applications. They are designed with cutting teeth on the face and edge of the body and can be used to cut a variety of materials in many directions. 

  • Square head mills  

Square Head Mills are used for general milling applications including grooving, profiling, and longitudinal cutting. 

  • Keyway End Grinders  

Keyway End Grinders are manufactured with smaller cutting diameters to provide a tight fit between the keyway groove they cut and the keyway or keyring. 

  • Ball end mills 

Ball end mills also known as ball end mills, are used for milling contoured, slotted, and pocketed surfaces. The ball head mill is composed of a circular cutting edge and is used in mold and die machining. 

  • Coarse mills 

Coarse mills also known as hog mills are used to quickly remove large amounts of material during heavier operations. The tooth design allows little or no vibration but leaves a coarser finish. 

  • Corner radius end mills  

Corner radius end mills have round cutting edges and are used where specific radius dimensions are required. Bevel end mills have an angled cutting edge and are used where a specific radius size is not required. Both types provide longer tool life than square head grinders. 

  • Roughing and finishing machines  

Roughing and Finishing end mills are used in a wide variety of milling applications. They remove heavy material while providing a smooth finish in one glide. 

Types of Flutes 

Flutes feature grooves or valleys that are cut into the body of the tool. A higher number of flutes increases the strength of the tool and reduces space or chip flow. End mills with fewer flutes on the cutting edge will have more chip space, while end mills with more flutes will be able to be used on harder cutting materials. 

  • Single Flute  

Single flute designs are used for high-speed machining and high-volume material removal. 

  • Four/Multiple Flute  

Four/Multiple flute designs allow for faster feed rates, but due to the reduced flute space, chip removal may be a problem. They produce a much finer finish than two and three flute tools. Ideal for peripheral and finish milling. 

  • Two Flute  

Two flute designs have the most amount of flute space. They allow for more chip-carrying capacity and are preeminent in slotting and pocketing nonferrous materials. 

  • Three Flute 

Three flute designs are just like two flute designs with higher strength. They are used for pocketing and slotting ferrous and nonferrous materials. 


Hence, this is all we must know about multi-flute end mills to know the cutting tool company better. If you want to buy better tools, our website is easily available on the internet.
