A Hex Broach is a tool that is used to create holes and other features in a metal, plastic, or other material. There are two main types of hex broaches. Internal broaches are found on the shank, and are held in place by a set screw in the whistle notch. External broaches are found on the outer flange and have a spindle cap and drive pin to keep them firmly in place.
The PCM Willen brand makes broaching tools that are compatible with almost any free-cutting metal. These tools can handle a tensile strength of 850N/mm2. However, heat treated steels and non-free-cutting stainless may reduce tool life. A chamfer of 60deg-90deg is typically used to make starting the broach easy. This chamfer prevents the broach from backing off after it has been inserted into a hole.
The rotary method is the most efficient and cost-effective way to broach a metal. Rotary hexagonal broaches can be used on all types of turning machines and can produce various shapes. These rotary tools are incredibly versatile, and can reduce auxiliary costs for the user. A hex broach is an indispensable tool for any shop. They are highly accurate and versatile and can be used in a variety of applications. Hex broaches are an ideal choice for fastener machining.
The hex broach holder is an important part of a machining center or lathe. It allows for fast application of a single tool without the need for complex motion or skilled labor. The holder rotates around the part as it cuts it, and the part will be fully-finished in one operation. When a hex broach is used in conjunction with a machining center, it can dramatically improve the efficiency of a shop’s production processes.
Hexagon broaches are available as HSS push type and can be used in a vertical broaching machine. External hexagon rotary broaches can be used on a variety of materials and can be sharpened multiple times. The hex broaches are usually available in standard sizes, or can be ordered on a per-print basis. Aside from the external hexagon rotary broach, you can also choose from various options for resharpening and machining.
Bone screws have also become popular in orthopedic applications. In fact, hex screws are used in a variety of applications, including those with Torx heads. These screws are typically 2.7mm or 3.5mm in diameter and 12 to 90 mm long. They are also commonly used in the biomedical industry. A rotary broach tool needs to have the right blend of toughness and wear resistance. In this case, carbide is a better option because it’s more durable than HSS.

While oil-based coolant will provide more lubricity, water-soluble coolants can be a good alternative. 100% synthetic coolant will shorten tool life. When using oil-based coolants, you can consider a TiN coating. This coating is effective in broaching most common materials, such as aluminum, cast iron, and nickel. However, a TiAlN coating will increase the lubricity of the tool, so you can expect better performance from your tool.
The type of Hex Broach you choose will depend on your needs and the material you’re working with. For example, you can purchase a square or a special-formed keyway broach. The former is cheaper and more widely used in automotive applications, while the latter is made of specially formed metal. Whether you need a broach for metal or plastic, you’ll be able to find one that fits your needs.
Internal and external broaches have face angles that create a sharper cutting edge. The face angles vary for different materials. Internal broaches are located inside the shank and hold in place by a set screw clamped on the whistle notch. External broaches are located on the outer flange and have a spindle cap or drive pin to hold them in place. While both types have the same function, they are different in the way they are used.
