How Do You Choose An End Mill

When picking an end mill for a particular milling operation, there are numerous possibilities as to which tool is best for the job. The product you are working with, the specific characteristics of the tool and coating choice, the device tool and the tool holding all play an important role and can have a significant impact on whether these things include value or considerable cost to your milling application.

Few steps in the machining procedure are as essential as picking the very best tooling alternative for your task. Making complex the process is the reality that each specific tool has its own distinct geometries, each essential to the eventual result of your part. We advise asking yourself key concerns before beginning the tool choice procedure. In doing so, you can make sure that you are doing your due diligence in choosing the best tool for your application. Taking the additional time to guarantee that you’re selecting the ideal tool will minimize cycle time, increase tool life, and produce a higher quality product.


Let us begin initially by understanding what is milling? Milling is a cutting procedure where we utilize a cutter to eliminate the material from the surface of a metal or workpiece. This cutter which we use has several turning cutting surface areas. Milling cutters play an important function in the milling procedure and they are utilized in several milling machines. Milling cutters are of numerous sizes and shapes.

Today, with innovative drilling makers, multi-faceted drill points are the norm. Not just do they need 50% less thrust, but they likewise produce 60% less heat than a conventional drill point. And there are a number of different setups, each of which– when combined with a particular drill point angle– appropriates for particular jobs.

Here are the things you need to consider when choosing a drilling end mill:

What Product am I Cutting?

Understanding the product you are dealing with and its homes will assist narrow down your end mill selection significantly. Each material has a distinct set of mechanical properties that offer them special attributes when machining. For example, plastic materials require a different machining technique– and various tooling geometries– than steels do. Selecting a tool with geometries customized towards those distinct characteristics will help to enhance tool efficiency and longevity.

When should you use end mill?

Do you require to dig a big hole? The big hole requires a big drill and big horsepower, which is the emphasize of spiral milling. Use a milling cutter with a size of 60-80% of the hole diameter to tidy up quickly, while leaving enough area for debris to getaway.

Need to level the bottom hole on the workpiece? Regular drills can’t do this, so you ‘d better remove this item from the drill’s worklist.

Required to produce a lot of holes of different sizes? Try to utilize end milling cutter, which can save time and area of tool altering.
