Iscar 5607512 Milling Insert Tpkt 1003PDR IC830 Carbide

Product Description

The ISCAR 5607512 is a solid carbide milling insert designed for high-performance face and shoulder milling in the HELI3MILL HM390 cutter series. Carrying the ANSI/ISO designation HM390 TPKT 1003PDR IC830, it features a triangular geometry with three usable cutting edges, a positive rake angle, and a helical cutting edge style. The IC830 grade substrate is coated with a Sumotec PVD AlTiN and TiN multilayer coating applied via physical vapor deposition, delivering wear resistance and thermal stability in demanding cutting applications. The PDR chip breaker geometry is engineered for controlled chip formation across a range of cut depths up to 0.315 inches. Licensed machinists and CNC tooling technicians are the primary installers of this insert.

This insert is suited for milling steel, stainless steel, superalloys, and titanium workpiece materials, covering ISO material groups P, M, and S. It is used in right-hand cutter bodies within the HM390-10 series, making it appropriate for both roughing and semi-finishing passes on machining centers running ferrous and exotic alloy components. The screw-clamping holding method provides secure seating in the pocket at elevated feed rates. The insert is supplied individually but must be ordered in multiples of 10 per manufacturer minimum order quantity.

Key Features

• Solid carbide substrate with Sumotec PVD AlTiN and TiN coating for extended tool life in steel and titanium
• Three cutting edges per insert - triangular TPKT geometry, single-sided
• Helical cutting edge style with PDR chip breaker for positive rake cutting action
• Maximum depth of cut of 0.315 inches (8.00 mm) for HM390 shoulder milling operations
• Right-hand orientation; screw-clamped insert holding for rigid pocket seating
• Compliant with ANSI and ISO 13399 tooling data standards

Compatibility

Designed for use in HM390-10 series cutter bodies. ANSI code HM390 TPKT 1003PDR IC830 and ISO code HM390 TPKT 1003PDR confirm fitment within ISCAR HELI3MILL HM390 shoulder milling systems accepting the 10 mm insert seat size.

Installation Notes

Insert seating and replacement are performed by qualified CNC tooling technicians or machinists following the cutter body manufacturer torque guidelines for the clamping screw. Ensure the cutter body pocket is clean and free of chips or debris before seating the insert. Always index or replace inserts with the spindle fully stopped and the machine in a locked-out, zero-energy state per applicable shop safety procedures. Handle carbide inserts carefully to avoid edge chipping prior to first use.
