Capabilities: Internal Splines & Serrations


Internal Spline Capabilities

•Pitch Diameters: 1/4″ to 48″
•Number of teeth: 4 teeth to 400 teeth
•Face Width: 9″ maximum face width
•Pitch Types: Diametral Combination Pitch (SAE/ ANSI Standard), Metric Splines (DIN 5480/ DIN 5482), Module Splines, Full Fillet splines, Flat Root splines, Major Diameter Fit splines, SAE Involute Serrations, Straight Sided splines, SAE 6 spline, SAE 10 spline, Metric Straight Sided splines.
(Other less common pitch cutters can be rented or purchased as needed).
•Tooth size: 120 Diametrial Pitch to 2 Diametral Pitch, .2 Module to 12 Module.
•Pressure Angle: 30° PA is the most common pressure angle for spline tools that we stock.
We also stock some 37.5° and 45° cutters.
(Other less common, pressure angle gear tools are available to rent or purchase as needed.)

Gear Materials

We can use a variety of materials to create your custom gear including steels, hardened steels, pre-heattreat steels, stainless steels, cast iron, aluminums, delrin (aceytl), nylon, uhmw and other plastics, non-metallics (phenolics), brass and bronzes, graphite, titanium, monel, inconel. We can and have made internal splines out of many other materials as well.
