Accupro 54020870 Solid Carbide Square Milling Insert

Product Description

The ACCUPRO 54020870 is a solid carbide milling insert designed for high-performance metal removal in indexable milling operations. Built to the XOLT insert style with a square shape and Size 13 designation, this insert features a CVD coating and the ACS35 manufacturer grade, making it suited for demanding cutting applications. It carries a positive rake geometry and a 9-degree relief angle for reduced cutting forces. With 4 available cutting edges and a corner radius of 0.0394 inches (1.00 mm), it delivers consistent edge life and predictable wear. Installation is performed by licensed machinists and CNC toolroom professionals as part of routine insert indexing cycles.

This insert is used in milling operations where the XOLT cutter series is deployed, typically in production machining environments running ferrous or non-ferrous materials. The single-sided, right-hand design and screw-held mounting method make it straightforward to index on compatible toolholders. Maximum depth of cut is 0.0394 inches (1.00 mm), keeping it well suited for finish or light roughing passes where edge integrity and surface finish consistency are priorities. The CI series designation ties it to a specific family of ACCUPRO milling tools.

Key Features

• Solid carbide substrate with CVD coating for extended tool life in milling applications
• ACS35 manufacturer grade optimized for consistent cutting performance
• 4 cutting edges per insert to maximize cost-per-edge value
• Positive rake geometry with 9-degree relief angle reduces cutting forces
• Corner radius of 0.0394 inches (1.00 mm) for controlled surface finish
• Screw-held, single-sided, right-hand insert for secure and repeatable seating

Compatibility

Designed for use with ACCUPRO XOLT cutter series toolholders, CI series. ISO code XOLT130410ERSCM identifies the exact insert geometry for cross-referencing with compatible toolholder seats.

Installation Notes

Insert indexing and replacement should be performed by a qualified machinist with the machine spindle fully stopped and the machine locked out per facility safety procedures. Use the appropriate torx or hex key specified by the toolholder manufacturer to secure the clamping screw to the correct torque per the toolholder documentation. Inspect the insert pocket and seating surface for chips or debris before seating a new insert. Never exceed the maximum depth of cut specification for this insert geometry.
