    Exact counterbores are very important and should never be taken for granted in any way. This is due to the role they are known to play when it comes to cutting holes accurately. If you are looking to cut holes on various surfaces, there is no need to bother. We have the exact counterbore cutters that can fit in.

    What Are Counterbores?

    Exact counterbores are a form of rotary cutting tools. Apart from using them to have an existing hole's opening enlarged, they can also help in holding the fastener. One of the reasons why counterbores have become popular is that they can make an end product look beautiful. Also, clearance can create problems during the process of manufacturing. These can be eliminated through counterbores.

    Counterboring is a process by which exact counterbores are used on milling machines. The intention is to have a hole created over screw clearance. With the aid of the hole which has been newly formed, the screw isn't going to stick out. Instead, it will rest in its place.

    Types of Exact Counterbore Cutters

    At this point, it is important to note that we have different kinds of counterbores. Understand their uses and features before deciding to choose the one that will be ideal for your project.

    • Cap Screw Counterbores - These can be used for cleaning or enlarging holes. They are also great when it comes to spot facing those spots that seem smaller.
    • Interchangeable Counterbores - These are useful in creation of recess for bolt, cap screw or spring. They can be used alongside interchangeable pilots ground in order to fit into various hole sizes which want to be counterbored.
    • Interchangeable Counterbore Pilots - Counterbores like these usually have flat on each shank's side. Interchangeable pilot style counterbores is what they are used with.
    • Filister Head Screw Counterbores - These are meant to create recess for flat head machine screws as well as small filisters.

    How To Make Exact Counterbores

    Follow the steps below to get this done:

    • Your workpiece should be placed in the milling machine's machine vice.
    • Have the drill bit replaced using a counterbore. Choose the right dimension since there are various exact counterbores.
    • The pilot should be placed inside your workpiece's hole.
    • Have the spindle turned on. At this point, the milling machine should be allowed to run. This should continue until the required dimensions are achieved.
    • Have the screwhead placed upside down in the counterbored hole. Check whether it fits in as expected.
