Hex and Open-End Broaches – Specialized Tools for Precision Machining of Wrench Head Cavities

Hex and open-end broaches are specialized push-broaching tools designed for machining the internal cavities (hexagonal or open-end profiles) of combination wrenches, open-end wrenches, and box wrenches, widely used in the hand tool manufacturing industry. The tools are precisely designed according to the internal cavity profile of the wrench head, completing the cavity forming in a single push-broaching pass with high precision and excellent efficiency. The series includes metric and inch series broaches, with dimensions customizable according to relevant standards including GB (Chinese), ANSI/ASME (American), DIN (German), and other international specifications—meeting the wrench head machining requirements of different global markets. They are indispensable specialized tools in the hand tool manufacturing industry.


Minor Diameter Centering Spline Broaches – Professional Solutions for High‑Precision Spline Machining

Minor diameter centering spline broaches are specialized pull‑broaching tools designed for high‑precision spline machining. Employing minor diameter centering technology, they ensure high concentricity between the spline minor diameter and major diameter through precise control of the minor diameter dimensions, thereby significantly enhancing spline pair transmission accuracy and service life. Manufactured from premium high‑speed steel (HSS) or powder metallurgy high‑speed steel (PM‑HSS) with precision CNC grinding, these broaches offer outstanding advantages including high production efficiency, superior machining accuracy, and excellent surface quality—making them particularly suitable for high‑volume production and high‑precision transmission applications in the automotive, aerospace, and construction machinery industries.
