Description
Product Overview
The HFS(R) 18‑piece No.10 HSS keyway broach set is engineered to meet the demanding requirements of modern machining environments. Constructed from high‑speed steel (HSS) that has been hardened and precision‑ground, each broach delivers a sharp, durable cutting edge that maintains its geometry even after repeated use. The set includes four broaches—two in style B (1/8″ and 3/16″) and two in style C (1/4″ and 3/8″)—providing a versatile range of sizes for common keyway dimensions. Complementing the broaches are nine collared bushings, carefully sized to match each broach style, ensuring optimal support and alignment during the cutting process.
Every component of this kit is housed in a compact, fitted box that not only protects the tools during transport but also organizes them for quick access. The box contains precision pullers, slotted bushings, and the necessary gaskets, allowing users to set up and begin work with minimal preparation time. The dimensions of the package—13.7 x 7.5 x 2.8 inches—and its weight of 8.3 pounds make it portable enough for on‑site applications while still providing the robustness required for shop‑floor use.
Designed with a focus on rigidity, the broaches feature a solid shank and a carefully calculated tooth geometry that balances material removal rate with surface finish quality. This balance reduces the risk of chatter and ensures a clean, accurate keyway profile, which is essential for the proper fit of rotating shafts and couplings. The collared bushings act as guides, maintaining the broach’s axial position and preventing deflection, which further enhances the precision of the cut.
Beyond the mechanical advantages, the set reflects HFS’s commitment to quality control and consistency. Each broach undergoes a rigorous heat‑treatment process followed by a final grinding stage to achieve the exact tolerances required for keyway machining. The result is a toolset that delivers repeatable performance, reducing scrap rates and increasing overall productivity for both small‑batch and high‑volume production runs.
Usage
This keyway broach set is ideally suited for a wide range of industrial and scientific applications where precise keyway slots are required. Typical use cases include the preparation of shafts for mechanical couplings, the creation of keyways in gear blanks, and the machining of pilot holes for assembly fixtures. The set works best when paired with a spindle press or a manual press that can provide a steady, controllable force, allowing the operator to feed the broach at a consistent rate for optimal chip evacuation and surface finish.
When using the broaches, the operator first selects the appropriate size based on the required keyway dimensions. The collared bushing is then installed on the workpiece to act as a guide, ensuring the broach remains centered throughout the cutting operation. The broach is inserted into the bushing and a gradual, uniform pressure is applied. This method minimizes the risk of tool breakage and produces a clean, accurately sized keyway that meets engineering specifications.
Because the set includes both metric and imperial size options, it can be employed in environments that adhere to different standards, making it a versatile addition to any machine shop’s inventory. The hardened HSS material allows the broaches to cut through a variety of ferrous and non‑ferrous alloys, including stainless steel, carbon steel, aluminum, and brass, without significant wear. This versatility reduces the need for multiple specialized tools, streamlining the workflow and lowering overall tooling costs.
For best results, users should ensure that the workpiece is securely clamped and that the press is calibrated to deliver the recommended feed rate. Regular inspection of the broach teeth for wear and the bushing collars for damage will extend the life of the set and maintain the high level of precision that HFS promises. When properly maintained, this set can provide hundreds of high‑quality cuts before any component requires replacement.
Why Choose Us
Choosing the HFS(R) keyway broach set means investing in a tool that combines durability, precision, and comprehensive support. HFS has a long history of manufacturing cutting tools that meet stringent industry standards, and this set is no exception. The use of high‑speed steel that is both hardened and precision‑ground ensures that each broach retains its cutting edge longer than comparable carbon‑steel tools, delivering consistent performance over an extended service life.
Our commitment to quality is reflected in the meticulous manufacturing process, which includes heat treatment, grinding, and final inspection to verify that each tooth profile meets exact tolerances. This attention to detail translates into reduced downtime for users, as the tools require fewer replacements and produce fewer defective parts. Additionally, the inclusion of collared bushings with each broach eliminates the need for separate purchases, providing a complete, ready‑to‑use solution straight out of the box.
Beyond the physical product, HFS offers responsive customer support and technical assistance. Whether you need guidance on selecting the correct broach size for a specific application or advice on optimal press settings, our knowledgeable team is available to help. We also provide after‑sales service, including tool sharpening and replacement parts, ensuring that your investment continues to deliver value long after the initial purchase.
Finally, the ergonomic design of the pullers and the organized packaging reduce setup time and improve workflow efficiency. By minimizing the time spent searching for the correct component, operators can focus on the machining process, leading to higher throughput and better overall shop performance.

FAQ
What material can the broaches cut?
The broaches are made from hardened HSS, allowing them to cut ferrous metals such as carbon steel and stainless steel, as well as non‑ferrous alloys like aluminum and brass, with consistent accuracy.
How do I select the correct broach size?
Choose the broach based on the required keyway width and depth. The set includes styles B (1/8″ and 3/16″) and C (1/4″ and 3/8″), each paired with matching collared bushings to guide the cut.
Can the set be used with a manual press?
Yes, the set is designed for manual spindle presses. Apply steady, uniform pressure while feeding the broach through the bushing to achieve a clean, precise keyway.
What maintenance is recommended?
Regularly inspect the broach teeth for wear and the bushings for damage. Sharpening or replacing worn components will maintain cutting performance and extend the tool’s lifespan.
Is technical support available?
HFS provides expert technical assistance for tool selection, setup, and troubleshooting, ensuring you get the most out of your broach set.
