Iscar 5606945 High Feed Milling Tip 4 Flute IC903

Product Description

The ISCAR 5606945 is a high feed end replaceable milling tip from the MM EFF (Multimaster/FeedMill) series, designed for indexable milling tool systems. Built from ultra fine grain carbide with an IC903 grade and PVD-applied TiAlN coating, this tip delivers reliable performance in high feed milling applications. The 4-flute geometry and 97-degree lead angle work together to maximize material removal rates at shallow depths of cut, making this tip well suited for aggressive roughing strategies where axial depth is limited. It is installed by qualified machinists and tooling specialists on Multimaster-compatible milling arbors and holders.

This milling tip is intended for right-hand cutting operations with a maximum depth of cut of 0.024 inches (0.6 mm) and a cutting diameter of 12.70 mm (approximately 0.500 inches). The 48-degree chamfer angle and 83-degree included angle are characteristic of high feed insert geometry optimized for hard materials and difficult-to-cut workpiece families. Applicable workpiece materials include steel, stainless steel, cast iron, non-ferrous metals, superalloys, titanium, and hard materials, covering ISO material codes P, M, K, N, S, and H.

Key Features

• IC903 grade ultra fine grain carbide substrate with PVD TiAlN coating for extended tool life in steel and stainless applications
• 4-flute high feed geometry with 97-degree lead angle for reduced axial cutting forces and higher feed rates
• Maximum depth of cut of 0.024 inches (0.6 mm) suited for high feed roughing passes
• Right-hand cutting orientation; no chipbreaker, no coolant-through
• Extension from holder of 0.6496 inches (16.50 mm); functional length of 0.6500 inches
• Conforms to ANSI standards; UNSPSC code 23291601

Compatibility

Designed for use with ISCAR Multimaster MM EFF series compatible holders and milling arbors that accept the MM EFF 127T4R2.59 insert size. Verify holder taper, bore size, and clamping mechanism against the specific MM EFF arbor specifications before ordering.

Installation Notes

Installation of replaceable milling tips should be performed by a qualified machinist or tooling technician. Ensure the milling machine spindle is fully stopped and locked out before mounting or removing the tip. Use the appropriate ISCAR Multimaster torque key or locking tool as specified for the MM EFF holder series; do not use open-ended wrenches or improvised tools on the tip seat. Inspect the holder pocket and seating surfaces for chips or wear before installing a new tip.
