Iscar 3346812 Indexable High-feed End Mill 0.472 in

Product Description

The ISCAR 3346812 is a 3-flute indexable high-feed end mill designed for aggressive material removal at shallow depths of cut. Built on a modular shank connection (T08 size), it accepts three FFT3WXMT030206T screw-lock inserts and delivers a maximum cutting diameter of 0.472 inches with a maximum depth of cut of 0.60 mm. The steel body supports through-coolant delivery, helping manage heat and chip evacuation during high-feed milling operations. This tool is intended for use by machinists and CNC tooling professionals running high-feed strategies on machining centers.

This end mill is suited for high-feed milling applications in production and job-shop environments where shallow axial depths and high feed rates are used to maximize metal removal rates. The modular T08 connection allows fast tool changes without removing the shank from the spindle. With an overall length of 22.50 mm and a head length of 15.00 mm, this is a compact tooling solution for tight-clearance and face milling work. It conforms to ISO 13399 tooling data standards, making it compatible with standard tooling management systems.

Key Features

• 3-flute design using FFT3WXMT030206T inserts secured by screw-lock clamping
• Maximum depth of cut of 0.60 mm supports high-feed, low-engagement strategies
• Through-coolant construction for improved chip evacuation and insert life
• Modular T08 shank connection enables fast, repeatable tool changes
• Maximum ramping angle of 4.70 degrees for controlled plunge-ramp entries

Compatibility

Designed for use with FFT3WXMT030206T inserts in the FFT3 toolholder series. Modular connection size T08. Conforms to ISO 13399 tooling data standards.

Installation Notes

Installation and tool changes should be performed by a qualified machinist with the spindle fully stopped and machine power locked out per shop safety procedures. Use the correct T08 modular interface torque procedure per the machine tool manufacturer's guidelines. Inserts must be seated fully before tightening the clamping screw; inspect insert pockets for chips or debris before each insert change. Verify coolant passages are clear and through-coolant pressure is within the machine tool's rated range before running.
