Iscar 5691263 Milling Insert Apcr 1003PDFR-P IC28 Carbide

Product Description

The ISCAR 5691263 is a solid carbide milling insert designed for use in helical milling cutters operating on non-ferrous metal workpieces. Manufactured to ANSI and ISO 13399 standards under ISCAR grade IC28, this insert carries a bright uncoated finish and features a positive rake geometry with a sharp cutting edge style. The parallelogram insert shape, 11-degree relief angle, and 0.50 mm (0.0197 inch) corner radius work together to deliver clean, low-force cuts in aluminum, copper, and other non-ferrous materials. With two cutting edges per insert, it delivers efficient material removal at a maximum depth of cut of 0.386 inches (8.00 mm).

This insert is suited for light-to-medium milling operations in residential shop environments and industrial production settings alike. It is compatible with the ISCAR HELIMILL series and specifically the HM90-10 cutter series. Typical applications include face milling, shoulder milling, and pocket milling of non-ferrous components. The screw-in holding method provides secure insert clamping and repeatable positioning during high-speed passes. Licensed machinists and CNC tooling technicians are the primary installers of this insert style.

Compatibility

Designed for use with the ISCAR HELIMILL series, specifically HM90-10 cutter bodies. Insert size code 1003 with inscribed circle range of 0.2500 to 0.3000 inches and length range of 0.4000 to 0.4500 inches.

Installation Notes

Installation is performed by machinists or CNC tooling technicians following the cutter manufacturer torque guidelines for the HM90-10 screw-in insert system. Always power down and lock out the spindle before seating or removing inserts. Inspect the cutter pocket seating surface for debris or damage before installing a new insert. Handle carbide inserts with care to avoid chipping the cutting edge prior to use.
