Product Description
The SECO 75004877 is a replacement wedge for indexable face mills in the Octo Mill series. Wedges secure the cutting inserts within the toolholder body, maintaining precise positioning during face milling operations. A properly seated wedge is critical for consistent depth of cut, surface finish quality, and insert retention at elevated spindle speeds. This component is used by machinists and toolroom technicians working with SECO Octo Mill face mill assemblies on CNC machining centers and manual knee mills. At 0.02 pounds, it is a lightweight precision component that should be replaced any time wear, deformation, or insert seating inconsistency is observed.
This wedge is designed for use in SECO Octo Mill indexable face mill toolholders. It is a direct fitment component for toolholder models R220.43-0063, R220.43-0080, and R220.43-0100-8160. Compatible wedge screws for this application are LD8018-T25P and LD8020-T25P. Installation is performed by machining professionals during toolholder maintenance, insert indexing, or after a crash event where wedge integrity may be compromised.
