Seco 74037153 Anvil for Indexables 0.375 Inch

Product Description

The SECO 74037153 is a precision anvil for indexable toolholders, designed to support ceramic, carbide, and other indexable inserts during cutting operations. The anvil seats beneath the insert in the toolholder pocket, distributing cutting forces and protecting the holder body from damage. This component is sized for a 0.375 inch inscribed circle insert and measures 1/8 inch in thickness. It is a consumable-grade replacement part installed by machinists and toolroom technicians during insert changes or toolholder maintenance on CNC lathes, mills, and boring setups.

This anvil is suited for use in indexable toolholder setups requiring a 0.375 inch IC insert seat. Toolholder insert size codes 12-3 and 16-3 are the designated size references for this anvil. It is compatible with anvil screw CA3507 and anvil key SMS795, making component sourcing straightforward when assembling or servicing a complete toolholder. Typical applications include production turning, facing, and boring operations where insert protection and consistent seating depth are required.
