SHARS 3/16″-B HSS Keyway Broach with SHIMS 404-9617 6.75″ Length

Description

Product Overview

The SHARS 3/16″-B HSS Standard Keyway Broach with SHIMS 404-9617 is a precision‑engineered cutting tool designed for the creation of accurate keyways in a variety of metal workpieces. Constructed from high‑speed steel (HSS), the broach delivers exceptional hardness and wear resistance, ensuring a long service life even under demanding machining conditions. The broach follows the B‑style geometry, featuring a keyway width of 3/16 inch and a matching back width, which provides consistent material removal and a clean, burr‑free finish. Its overall length of 6‑3/4 inches offers ample reach while maintaining a compact profile that fits comfortably into standard tool holders. Weighing just 4 ounces, the tool is lightweight enough for extended use without causing operator fatigue. The package includes a single precision shim, calibrated to maintain optimal alignment and reduce deflection during cutting, thereby enhancing dimensional accuracy and repeatability. This broach is not discontinued by the manufacturer, and it remains a popular choice among professionals, as reflected by its #73 ranking in the Broaches subcategory on Amazon and a perfect 5‑star customer rating.

Usage

Designed for industrial and scientific applications, this keyway broach excels in environments where precision and reliability are paramount. It is ideally suited for machining keyways in shafts, gear blanks, and couplings across automotive, aerospace, and heavy‑equipment sectors. The tool’s HSS construction allows it to cut through hardened steels, stainless steels, and alloyed materials without excessive wear, making it a versatile solution for both production runs and custom job shops. Operators can employ the broach in CNC machines, manual lathes, or dedicated broaching stations, adjusting feed rates to match material hardness and desired surface finish. The included shim ensures that the broach maintains proper alignment within the tool holder, reducing the risk of misfeeds and guaranteeing tight tolerances—critical for applications where keyway fit is essential for power transmission. Its lightweight design facilitates quick tool changes, minimizing downtime in high‑volume manufacturing settings. Whether you are producing standard 3/16″ keyways or need to retrofit existing equipment with a reliable cutting solution, this SHARS broach delivers consistent results.

FAQ

What materials can this broach cut?

The broach is made from high‑speed steel, allowing it to cut hardened steels, stainless steels, alloy steels, and other common industrial metals without excessive wear.

How do I install the shim correctly?

Place the shim between the broach shank and the tool holder, ensuring it sits flush against both surfaces. This alignment eliminates play and maintains the tool’s straightness during cutting.

Can this broach be used in CNC machines?

Yes, the broach’s standard shank dimensions are compatible with most CNC lathe and broaching stations. Adjust feed rates according to material hardness for optimal results.

What is the recommended feed rate for stainless steel?

For stainless steel, a moderate feed rate of 0.0015–0.0025 inches per revolution is recommended, combined with adequate coolant to prevent overheating.

Is there a warranty or guarantee?

Shars offers a limited warranty covering manufacturing defects. Contact our support team for replacement or repair options if the tool does not meet quality expectations.
