The result is a generated involute tooth in a single setup. A shaper cutter looks like a gear and reciprocates up-and-down through the blank, indexing one tooth at a time. Hobs are faster and more accurate for production; shapers can cut internal gears and gears with shoulders close to the tooth (which a hob cannot reach).\u003c\/p\u003e\u003c\/div\u003e\u003c\/details\u003e \u003cdetails class=\"gc-faq-i\"\u003e\u003csummary\u003eWhat is module and how do I read a gear-cutter spec?\u003c\/summary\u003e\u003cdiv class=\"gc-faq-body\"\u003e\u003cp\u003eModule (M) is the metric unit of tooth size: M = pitch diameter ÷ number of teeth (millimetres per tooth).
