What are the features of single flute end mills?

Single flute end mills are versatile cutting tools used in a variety of applications. From creating straight cuts in wood and plastics to contouring and slotting in metalworking. These end mills feature a single flute, or cutting edge, which makes them fast and efficient at material removal.

In this article, we will discuss the features of two types of single flute end mill: carbide and coated.

Carbide Single Flute End Mill:

They are made from a combination of tungsten carbide and cobalt. The carbide provides high hardness and wear resistance, while the cobalt helps boost toughness and resistance to chipping.

Here are some of the features of carbide single flute end mills:

  1. High Hardness – Carbide end mills have a high hardness rating of HRC 65-68, making them suitable for machining hard materials such as stainless steel, titanium, and hardened steels.

  2. Better Wear Resistance – Carbide’s wear resistance property allows the end mill to maintain its sharpness for longer, resulting in improved tool life and reduced tool replacement costs.

  3. High Dimensional Accuracy – Carbide end mills offer high dimensional accuracy due to their high stiffness and low deflection rates, making them ideal for precision cutting.

Coated Single Flute End Mill:

They are made from tungsten carbide and cobalt too. Coated with a thin layer of Titanium Nitride (TiN), or other coatings. The coatings enhance cutting performance by reducing friction and heat generation during cutting.

Here are some of the features of coated single flute end mills:

  1. Improved Cutting Performance – Coatings on the end mill reduce build-up of materials on the cutting edge, resulting in better chip formation and improved cutting performance.

  2. Reduced Heat Generation – The coatings minimize heat generated during cutting, which prevents material deformation and prolongs tool life.

  3. Cost-Effective – Coated end mills are a cost-effective alternative to carbide end mills, and are suitable for a wide range of materials, including aluminum, copper, and brass.


Single flute end mill is a kind of popular cutting tools, thanks to their ability to make fast and efficient cuts in a variety of materials. Carbide and coated single flute end mills are two popular types, each with its unique features and advantages. Whether you choose carbide or coated end mills will depend on your application, budget, and specific requirements.
