An involute spline broach is a high-precision cutting tool designed to generate internal involute spline profiles in a single linear stroke. Manufactured from premium tool steels and engineered with controlled tooth geometry, these broaches ensure exceptional dimensional accuracy, repeatability, and surface finish — even in demanding production environments.
A straight spline broach is designed to generate internal parallel-sided spline profiles in a single, accurate broaching stroke. These broaches are essential for components requiring precise rotational engagement, high torque transmission, and repeatable fit accuracy.
Manufactured to strict dimensional standards, straight spline broaches from Ashok Long Life Tools Engineering deliver exceptional consistency, tool life, and surface finish.
A ROUND BROACH ( Pull Type or Push Type)is a precision-engineered cutting tool used to generate or size perfectly round internal holes with superior dimensional accuracy and surface finish. These broaches are commonly used after casting, drilling, or rough machining to achieve the final required diameter in a single, controlled pull stroke.
Round broaches from Ashok Long Life Tools Engineering are designed for consistent performance, excellent finish, and long tool life — ideal for high-volume production.
A keyway broach is a specialized cutting tool designed to machine internal keyways and straight slots inside cylindrical bores with exceptional accuracy. In a single controlled pull stroke, these broaches deliver perfectly dimensioned keyways without the need for milling or slotting operations.
Engineered with progressive tooth geometry and manufactured using premium tool steels, Ashok Long Life Tools Engineering keyway broaches ensure high repeatability, minimal burr formation, and long tool life — making them ideal for high-volume production environments.
A square and hax broach is designed to machine internal square holes with high dimensional accuracy in a single broaching stroke. These broaches are used when components require positive torque locking, multi-sided engagement, or precise mechanical indexing.
Square broaches from Ashok Long Life Tools Engineering are engineered with progressive tooth geometry and SPM-ground profiles to ensure consistent accuracy, clean corner formation, and excellent surface finish.
Plug gauges are precision inspection tools used to verify the internal diameter, roundness, and dimensional accuracy of holes, bores, and machined components. Manufactured to strict tolerance classes and gauge standards, plug gauges ensure consistent quality control in high-volume and precision-critical industries.
At Ashok Long Life Tools Engineering, we manufacture a full range of plug gauges — from standard GO/NO-GO types to highly customized profiles — with micron-level accuracy and exceptional durability.
At Ashok Long Life Tools Engineering, every broach and gauge we manufacture is engineered with micron-level accuracy. From SPM profile grinding to multi-stage inspection, we ensure perfect geometry, consistent tolerances, and superior surface finish. Our tools deliver dependable performance in high-volume production environments where precision is non-negotiable.
Equipped with state-of-the-art SPM machines, heat-treatment systems, and precision measuring instruments, we provide complete tooling solutions — from new broach manufacturing to expert reconditioning and gauge calibration. Our advanced processes enhance tool life, reduce downtime, and ensure maximum value for our customers.
Quality is the foundation of everything we build. Each tool undergoes strict dimensional checks, hardness verification, and profile inspection before dispatch. With fast delivery timelines, tailored tooling solutions, and responsive technical support, we are dedicated to helping manufacturers achieve consistent accuracy, improved productivity, and long-term reliability.
