Hex Broaches – What You Should Know

Hex Broaches are tools for cutting hex shapes in metal products. They start with a standard pilot hole and are equipped with handwheels for precise positioning. Hex broaches come in two sizes: metric and imperial. To use one, you need to know the right size for the product. If you have difficulty locating the hex in your metal part, you can use a rotary tool for a more accurate result.

Rotary Tool

One of the most commonly used rotary broaches is a hex holder, which fits onto a rotary tool. These holders are available in different sizes and can be used for various applications. A rotary hexagonal broach is a versatile tool that can produce various shapes, including square, hex, and star. They are highly accurate and reduce auxiliary costs.

While a rotary hex broach drills a hole 1% larger than the hex profile, the hex nut is manually removed from the workpiece after drilling. Because of this inherent problem, the hex nut can only be drilled halfway through, making it impractical for broaching a full-form hex. Although the hex nut size is usually 1.3 to 1.5 times its ID, it may still be used for other applications. The rotary tool is also designed to drill a hole with a one-degree offset.

HSS Push Type

If you’re looking to make a hexagon hole in metal, hex broaches are your best choice. They offer the fastest hex form of any type of broach. And because they are push-type, they require less pressure than three-point broaches. Hex broaches are often used to punch hex holes in sockets, jigs, and fixtures. They can be operated manually or using a hydraulic arbor press.

Push-type keyway broaches come in the most common Metric sizes and P9 tolerance. They’re typically used with “A” or “B-1” bushings. If you need something larger than 18mm, you’ll need “Special Bushings”; we carry these in stock. Whether you use a vertical broaching machine or a hydraulic press, you’ll find a hex broach that meets your needs.

Forming Tool

Hexagonal broaches are tools used to form holes or other parts’ features. They can create internal or external hex features in different materials. They are available in two main types: internal and external. Internal ones are located on the shank and are held in place with a set screw clamped into the whistle notch. External broaches are attached to the outer flange and are held in place with a drive pin and spindle cap.

Hex broaches are widely used for machining applications, including fasteners. Their offset design makes them ideal for high-speed applications. They are also highly versatile – they work on all types of turning machines and can be adjusted to fit nearly any material. Rotary broaches are best for FRC applications and can be used to create many shapes, including hex nuts. The downside to rotary broaching is that you must adjust the spindle RPM for the correct fit.

Keyway Broach

If you’re looking for a keyway hex broach, you may choose between a standard square and a specially-formed one. A standard square broach will be cheaper than a keyway broach, so choose wisely. Hex broaches are a versatile way to machine hex-shaped parts, and they’re ideal for various applications. To find the right keyway broach for your application, consider the following tips.

A single-point keyway broach is a popular type for blind and through-hole operations. Its single-point design allows it to be sharpened several times, extending tool life. On the other hand, around the keyway broach is a single-pass cutter, which cuts the full width and depth of the workpiece in one pass. In addition, production-type keyway broaches are designed for long, high-speed production runs and feature self-supporting shanks.
