Accurate and reliable tools for smooth spline cutting

Involute Spline Broaches are specially designed for accurate internal spline cutting. They create correct tooth shape, proper involute profile, and even spacing. This helps achieve smooth cutting, good surface finish, and reliable results in regular spline machining work.
Made from strong and durable material, involute spline broaches offer long working life. the balanced tooth design reduces cutting pressure, lowers vibration, and helps machines run smoothly during continuous production and heavy-duty spline cutting operations.
Involute Spline Broaches use a progressive tooth structure that removes material step by step. This ensures uniform cutting, better dimensional accuracy, reduced tool load, and consistent spline quality across all components in batch and mass production.
Heat-treated cutting edges in involute spline broaches improve hardness and toughness. This protects the tool from early wear, chipping, and edge damage while maintaining sharp cutting performance during long machining cycles.
Accurate profile grinding in involute spline broaches ensures correct pitch and smooth spline engagement. This helps produce reliable splines used in automotive parts, gearboxes, and power transmission components requiring tight tolerance and strong fitting.
Dedicated Impex manufactures involute spline broaches under strict quality control. Each broach is checked for profile accuracy, pitch consistency, and surface quality to ensure dependable performance in demanding industrial applications.
Involute Spline Broaches can be used on different materials such as carbon steel, alloy steel, and non-ferrous metals. This makes them suitable for various industries requiring flexible and reliable spline cutting solutions.
DIC ensures precise shank and pull-end grinding for proper alignment. This improves tool stability, reduces machine stress, and supports accurate spline cutting in manual, automatic, and high-speed broaching machines.
