Tool Incorporates Square, Single Sided Insert with Increased Clearance Angles

Iscar presents the Fast Feed Quad (FFQ4) mills for high-feed and rough milling applications. The tool’s design incorporates a square, single-sided insert with increased clearance angles (both radial and axial) and four cutting edges. The FFQ4 features a 9-degree cutting edge angle for long reach, and positive rake angle position for the insert in the cutter body. According to the company, this design supports enhanced performance in terms of insert and tool life when milling difficult-to-machine materials, like austenitic stainless steel and high-temperature alloys.

Two new insert grades have been introduced: Grade IC1882 and Grade IC5820. The IC882 features a tough submicron substrate with AlTiN+TiN PVD coating and a special surface treatment, and is designed for machining austenitic stainless steel, titanium and high-temperature alloys. The IC5820 has a tough submicron substrate with a MTCVD alpha Al2O3 coating and a special surface treatment for machining austenitic stainless steel, titanium and high-temperature alloys, and is capable of withstanding higher surface speeds than IC882.
