Indexing Heads & Spacers

Indexing heads, also called dividing heads or spiral heads, are specialized tools which enable circular indexing of workpieces (precise rotation to present angles or circular divisions). Indexing heads are typically used on milling machines tables, but also on drill presses, boring machines and grinders. Indexing head operations include machining the flutes of a milling cutter, cutting the teeth of a gear, milling curved slots, or drilling a bolt hole circle around the circumference of a part.
