Value Collection 428-9707 Spider Handle Bridgeport Heads

Product Description

The VALUE COLLECTION 428-9707 is a spider handle designed for use with Bridgeport milling machine heads. Spider handles provide the mechanical grip point used to rotate and adjust the quill or spindle assembly on vertical milling machines. This handle installs in the bore of the head assembly and gives the operator the leverage needed to make precise manual adjustments. With a 1-inch bore size and 1-inch overall length, this is a direct-fit accessory for standard Bridgeport-style heads. Machinists, tool-and-die technicians, and machine shop maintenance personnel are the primary installers. The part weighs 1.5 pounds.

This spider handle is suited for use on Bridgeport milling machine heads in job shop, production, and maintenance environments. It serves as a replacement or spare accessory for shops running Bridgeport-style vertical mills where the original handle has worn, stripped, or gone missing. The compact 1-inch overall length makes it appropriate for standard head configurations without clearance concerns. Typical applications include manual quill operation and head adjustment tasks on knee mills.
