Bridgeport 12200098 Quill Lock Handle I Series Milling

Product Description

The BRIDGEPORT 12200098 is a quill lock handle designed as a direct replacement part for Bridgeport milling machines. The quill lock handle secures the quill at a set depth during milling operations, preventing unwanted vertical movement and maintaining consistent cut depth. It fits within the lower housing of 2J and J-Head style machines and is a common wear or damage replacement for shops keeping vertical knee mills in service. Machinists and maintenance technicians performing part-level repairs on Bridgeport-style mills will find this a straightforward swap.

This handle is intended for use with I Series Bridgeport milling machines. It mounts in the 2J and J-Head lower housing, making it applicable to one of the most widely used vertical knee mill configurations in machine shops, vocational programs, and light manufacturing facilities. It is sold individually and is a stock replacement component for routine maintenance or collision-damaged quill assemblies.

Installation Notes

Installation is typically performed by a machinist or qualified maintenance technician. Before replacing the quill lock handle, power down and lock out the machine per OSHA lockout/tagout procedures. Standard hand tools are sufficient for most handle replacements on knee mill quill assemblies. Verify fit and full engagement of the locking mechanism before returning the machine to service.
