Iscar 5607644 T-slot Milling Tip 1.238 in 8 Flute IC908 Carbide

Product Description

The ISCAR 5607644 is a T-slot replaceable milling tip designed for use with compatible SD-SP series milling bodies. Manufactured from sub-micrograin carbide in the IC908 grade with a PVD-applied TiAlN coating, this tip delivers consistent performance in demanding milling applications. It carries a 1.238-inch cutting diameter, a 0.125-inch cutting width, and a maximum depth of cut of 0.315 inches. The 8-flute configuration supports higher feed rates and improved surface finish in production environments. Right-hand cutting geometry and a 90-degree lead angle make this tip suited for standard T-slot milling operations across a broad range of workpiece materials.

This milling tip is intended for T-slot machining operations in shop, production, and job-shop environments. It is compatible with materials including steel, stainless steel, cast iron, non-ferrous metals, superalloys, titanium, and hard materials, covering ISO material codes P, M, K, N, S, and H. Typical applications include milling T-slots on machine tables, fixtures, and structural components where precise slot geometry and flute count are critical to chip evacuation and cycle time.

Key Features

• IC908 sub-micrograin carbide grade with PVD TiAlN coating for extended tool life on hard and abrasive workpiece materials
• 8-flute design supports high feed rates and efficient chip evacuation in T-slot operations
• 1.238-inch cutting diameter with 0.125-inch cutting width for standard T-slot profiles
• Maximum depth of cut of 0.315 inches suitable for full-depth T-slot passes
• Right-hand cutting, 90-degree lead angle, no chipbreaker - straightforward setup with compatible SD-SP holders
• ANSI-standard geometry; no coolant-through requirement simplifies setup in standard machining centers

Compatibility

Designed as a replaceable tip for ISCAR SD-SP series milling bodies, specifically the D1.25-H125D insert size designation. Verify holder compatibility using the full milling tip description SD D1.25-H125D-SP15 before ordering.

Installation Notes

Installation of replaceable milling tips should be performed by a qualified machinist or tooling technician. Disengage machine power and confirm the spindle is fully stopped before tip exchange. Use the appropriate torque wrench and seating tool specified by the holder manufacturer - do not over-torque the clamping screw. Inspect the seating pocket for chips or damage before installing the new tip to ensure proper seating and runout.
