Involute Spline Rotary Broach Tool

Involute Spline Rotary BroachInvolute spline rotary broach shapes are popular forms used for connecting driven components in machines and vehicles. Typical examples would include gear shifters on motorcycles and clamps for engine shafts. Standard splines and involute splines control power transmission by the way contact is designed into the teeth.

Involute Spline rotary broach tools can be made to international standards or custom made to your specifications. However, most are made to the customer’s specified dimensions. Due to the wide variety of tolerances, tooth width and custom features, Polygon Solutions cannot stock standard spline broaches.

The size of involute spline forms that can be made by rotary broaching is limited by the amount of material to be removed. Usually, material removal (or tooth height) is limited to .025” per side. This limitation keeps most involute spline forms under 1 inch diameter.

Oversize pilot holes are required for all involute spline form rotary broaching applications. The pilot hole will leave a small radius at the inside corners. This radius is often acceptable because contact is still made at the outside of the form.
