Square Broaches

We are a Manufacturer of Square Broaches, also known as “square hole broaches” or “square push broaches.” These are ideal for cutting square forms in metal products simply using a pilot hole and required broach. Our Square Broaches are mainly designed to generate, in one pass, a square hole in a previously cast or drilled round hole.

Square Broaches are available in standard and non-standard sizes with all types of latest PVD coatings. These broaches are suitable for a wide range of materials, including Steel, Cast Iron, Brass, and Aluminum. Custom profiles can be manufactured to meet specific production requirements. The broaches ensure consistent performance and long tool life even under heavy-duty operations.

Our technical team is available to assist with selection, customization, and optimization of broaching solutions for maximum efficiency. Super Tools ensures every broach delivers superior quality, precision, and value for your manufacturing needs.

Product FAQ’s

Q. What is a square broach and where is it used?

A square broach is a precision cutting tool used to produce accurate internal square holes or profiles in metal components through a single continuous broaching operation. It progressively removes material with a series of teeth to achieve sharp corners, tight tolerances, and excellent surface finish.

Q. How does a square broach different from other internal broaches?

A square broach is specifically designed to produce internal square profiles with sharp corners and uniform geometry, unlike other internal broaches that create round, spline, keyway, or special shapes. Its tooth geometry and rise per tooth are optimized to maintain corner accuracy and dimensional consistency throughout the cut.

Q. Are Square Broaches available in both push and pull types?

At Super Tools, square broaches are manufactured in both push-type and pull-type designs to suit different broaching machines, component sizes, and cutting forces, ensuring accurate square profiles, smooth cutting action, and consistent performance in both light- and heavy-duty applications.

Q. Can square broaches be re-sharpened after wear?

Yes, square broaches can be re-sharpened after wear by regrinding the cutting faces while maintaining the original tooth geometry.
Re-sharpening restores cutting performance and extends tool life when done within allowable stock removal limits.
Professional regrinding ensures accuracy, surface finish, and dimensional consistency of the square profile.

Q. What is the maximum square size that can be broached internally?

The maximum internal square size that can be broached depends on the broaching machine capacity, broach design, and workpiece material. Larger sizes are possible with custom broaches and presses, but require higher pulling force, rigid fixturing, and precise alignment.

Q. What is the difference between form-relieved and ground square broaches?

Form-relieved square broaches have teeth that are relieved by form grinding, making them easier to re-sharpen while maintaining the square profile, and they are commonly used for standard, high-volume applications. Ground square broaches are fully precision-ground on all cutting faces, offering higher dimensional accuracy and superior surface finish, which makes them suitable for tight-tolerance and critical components.

Q. Who is the top Square Broaches Manufacturer in India for precision internal broaching applications?

Super Tools Corporation is recognized as a top Square Broaches Manufacturer in India, known for precision manufacturing, custom broach solutions, and consistent export-quality performance across diverse industrial applications.

Q. Can square broaches be designed with progressive or variable tooth pitch?

Yes, square broaches can be designed with progressive or variable tooth pitch to gradually increase cutting load along the broach length. This design improves chip control, reduces cutting forces, and minimizes tool wear and vibration. Progressive tooth pitch is especially beneficial for tough materials and high-precision square broaching applications.

Q. Are square broaches suitable for ferrous and non-ferrous materials?

Yes, square broaches are suitable for both ferrous and non-ferrous materials when designed with the correct tool material and tooth geometry. They are commonly used on steels, cast iron, aluminum, brass, bronze, and other alloys with optimized rake angles and coatings. Proper broach design ensures smooth cutting, good surface finish, and long tool life across different material types.
