Metric keyway broaches for internal keyways

Metric keyway broaches are used for cutting straight internal keyways in hubs, gears, pulleys and other bored components. A good broach set makes the work repeatable, accurate and efficient when the part needs to fit a keyed shaft securely.

The NOVA keyway broach sets are designed for practical workshop use. Hardened broaches provide long service life when used with correct alignment, suitable lubrication and a steady press force.

Choosing the right keyway broach set

Start by checking the required keyway width, the bore diameter of the workpiece and the key standard used in your application. The range includes sets for common metric keyway sizes such as 4–8 mm and 10–14 mm, making it easier to choose a compact set for smaller work or a larger set for heavier components.

For repair and maintenance work, a set is often the most convenient choice because several sizes are ready when shafts, hubs and replacement parts vary from job to job. Individual replacement broaches are also useful when one size is used frequently.

What is needed for keyway broaching?

Keyway broaching is normally done with an arbor press or hydraulic press. The broach is guided through the bore with a suitable bushing, and shims are used when the keyway depth needs to be increased in controlled steps.

For best results, keep the broach aligned with the bore, use suitable cutting fluid and avoid forcing the tool at an angle. Clean chips between passes and inspect the cutting edges regularly.
