A Basic Understanding of Hex Broaches

Hex Broaches

Hex Broaches are used to drill holes in different materials. They are most commonly used for bolts and nuts. The hex nut size is approximately 1.3 to 1.5 times the diameter of the workpiece, so the diameter of the hole should be at least 1% larger than the hex profile. The hex nut can be drilled partially or fully through the material. The hex nut size is often smaller than the ID of the workpiece, but can be used for other applications.

Hex broaches can also be used for fasteners that are hexagonal in shape. The broaching process can remove all metals from hexagonal fasteners, but sometimes it is not enough. To learn more about hexagonal broaches, continue reading. This article will give you a basic understanding of the hex broach and how it works. It also will provide you with a step-by-step process to get the job done correctly.

Hex broaches are specialized tooling that allow you to make accurate hex shapes into metal products. They start by creating a pilot hole with the right size and then drill into the metal. Some types of hexagon broaches come with a hand wheel for accurate locating. Hex broaches are made in metric and imperial sizes. The size is not very important but it does depend on the type of workpiece that you are working on.

Before you begin the broaching process, you should make sure the hole is 1.3 to 1.5 times the part’s OD (across-point diameter). After the hole is drilled, you can also counter-bore it with a smaller drill to ensure a concentric fit. This technique is especially helpful when working on aerospace parts. In these cases, you cannot use radius drilling along the walls of the broached hole. Shop hexagonal broaches from Somma Tool.

When you’re setting up your tool for broaching, you should ensure that it has a long tailstock and good metric drill rod. The holder’s tailstock needs to be centered on the back end of the toolholder, with the cutting edge at the correct distance from the tailstock. Once the holder has been properly adjusted, you can remove the spindle and replace it with the broach. This process is also quick and easy, but you should always make sure that you keep your tool safe while broaching.

Rotary broaching is another option for cutting polygons. This method is also fast and produces both internal and external polygons on a rotating workpiece. This method can also produce forms with precision better than 0.0005″. They are available from suppliers and can be used for a variety of applications. If you need to make a lot of polygons, you can buy a rotary broaching machine. The best part about it is that they are inexpensive and easy to use.
