The invention discloses a rotary drill die, which comprises a drill die clamp body (1) and a drill template (2) located at the upper end of the drill clamping fixture body (1), a drill casing (3) on the drill template, a graduation locator (4) in the upper half of the drill clamping fixture body, and a through hole (5) on the drill clamping fixture below the indexing locator. A convex font bushing (6) is provided on the through hole, the convex shaped bushing is made of metal rubber, and the surface of the convex shaped bushing is provided with a frictional line. The convex shaped bushing is provided with a locking nut (7), one end of the locking nut is sequentially connected with a indexing plate (8), a positioning core shaft (9) and a clamping nut (10), and the workpiece is located in the position. The core is on the shaft. The invention adopts a rotary drilling model with high machining precision, compact structure, and a convex shaped bushing fitted on the through hole, which can make the structure more stable and stable, and the scale of the dividing plate is set on both sides, so it is easy to observe.
