CNC Cutting Tools - All You Need To Know

CNC Cutting Tools – All You Need To Know

If you’re interested in learning more about CNC cutting tools, this article is for you. In this article, we’ll discuss the differences between Bull nose end mills and square end mills, threading taps, and High-speed steel, and more. Whether you’re an industrial designer or are in the process of purchasing your first machine, this article will provide you with all the information you need to make an informed decision.

Square end mills


Square end mills in CNC cutting tools are used in general milling applications. These mills produce a sharp edge at the bottom of pockets and slots. Their cutting heads feature flutes to divert the chips away from the workpiece. Square end mills are used both on CNC cutting tools and manually operated milling machines. Here are some important facts about these mills. To use one, you must know the type of workpiece you will be milling.

Bull nose end mills

One of the most versatile CNC cutting tools is a bull nose end mill. These tools are great for roughing applications and can be customized to meet a variety of applications. Large-core ball nose end mills are a great choice for roughing softer steels, while sharper designs can produce more predictable results. Ball nose end mills are commonly paired with conventional tools, including drills and router bits.

Threading taps

There are several types of threading taps. The spiral flute thread taps use fewer teeth than a regular hand tap. The spiral flute design helps chip breakage and gives more room for lubricant to enter. Threading taps can be either solid or insert carbide. Thread taps used for CNC operations are a step above hand taps. If your CNC cutting tools need to produce internal screw threads, it’s essential to choose the right tap.

High-speed steel

This report provides an overview of the high-speed steel market, including its characteristics, applications, and future trends. It outlines the market by geography and product, and offers forecasts for the next five years. High-speed steel has been used for cutting tools since the beginning of the 20th century, but it is gradually being replaced with powder metal-based inserts. High-speed steel cutting tools are produced by sintering or metal injection molding, and the end-users of high-speed steel cutting tools will benefit from its sharpness and corrosion resistance.

Ceramic materials

This study evaluated the efficiency of different types of CNC tools for ceramic materials. The efficiency of tools was assessed based on cutting forces, cumulative process energy demand and surface roughness of the machined workpiece.


The results showed that the ceramic tools had a lower energy demand, exhibited less tool wear and produced less surface roughness. However, further studies are needed to verify the presented results and determine the economic benefits. In the meantime, CNC cutting tools for ceramic materials have the potential to improve the performance of machining processes.
