Value Collection BS-1 Semi-universal Dividing Head 3MT

Product Description

The VALUE COLLECTION BS-1 is a semi-universal dividing head designed for precision indexing and gear-cutting operations on milling machines. It accepts a 3MT (Morse Taper No. 3) headstock taper, allowing direct mounting of compatible tooling and arbors. With a 5.04 inch centerline height, the unit positions workpieces at a consistent, repeatable reference height above the machine table. Weighing 79 pounds, this is a robust, cast-iron-class fixture intended for machine shop environments. Installation and setup are handled by machinists and toolroom technicians working with manual or CNC knee mills and horizontal milling setups.

The BS-1 suits toolroom, job shop, and production machining applications where angular indexing, flute spacing, gear tooth cutting, or polygon milling is required. The semi-universal configuration supports both direct and differential indexing methods, expanding the range of division counts achievable with the included index plates. The complete set includes the dividing head, indexing plates, and a tailstock for supporting longer workpieces between centers. Overall footprint is 9.52 inches long by 6.61 inches wide by 8.66 inches high, making it compatible with mid-size knee mill tables.

Installation Notes

Installation is performed by a qualified machinist or toolroom technician. Secure the dividing head body to the milling machine table using appropriate T-slot hardware and verify alignment with a dial indicator before cutting. Power down and lock out the milling machine spindle before mounting or adjusting the dividing head or tailstock. Consult the machine tool manufacturer documentation for table load ratings before positioning this 79 pound assembly.
