Kennametal 1803178 Square-shoulder Face Mill 3in

Product Description

The KENNAMETAL 1803178 is an indexable square-shoulder face mill designed for precision milling operations in metalworking and machining environments. Built around the Fix-Perfect series platform, this tool accepts five BGHX 15L5 inserts and delivers a maximum cutting diameter of 3 inches with a maximum depth of cut of 0.394 inches. The 1-inch arbor hole and overall height of 1.75 inches make it a compact, rigid body for high-accuracy shoulder and face milling. Through-coolant capability supports chip evacuation and extended insert life during continuous cuts. This tool is installed and operated by machinists and CNC tooling specialists in production and job-shop settings.

This face mill is suited for square-shoulder milling applications on ferrous and non-ferrous materials where a true 90-degree wall is required. The 0/90 lead angle produces a square shoulder profile in a single pass, making it effective for step milling, face milling, and pocketing operations on vertical and horizontal machining centers. The coarse pitch configuration with five flutes supports stable cutting at moderate feed rates. Through-coolant compatibility makes it appropriate for applications requiring thermal management and consistent surface finish.

Key Features

• Maximum cutting diameter of 3 inches with a 0.394-inch maximum depth of cut
• Accepts five BGHX 15L5 inserts with a clamp-style insert holding method
• 0/90 lead angle produces a true square shoulder in a single pass
• Positive rake angle of 24 degrees reduces cutting forces and promotes free cutting action
• Through-coolant design improves chip control and insert longevity
• Fix-Perfect series body with coarse pitch and right-hand cutting direction

Compatibility

Designed for use with BGHX 15L5 series inserts. Compatible with machine spindles accepting a 1-inch arbor hole. Verify spindle interface, torque capacity, and RPM range against machine tool specifications before installation.

Installation Notes

Installation should be performed by qualified machinists or CNC tooling personnel. Ensure the machine spindle is fully powered down and locked out before mounting or removing the cutter body. Verify arbor fitment, drawbar torque, and insert seating before initiating any cutting cycle. Follow the machine tool manufacturer guidelines for maximum allowable RPM at the specified cutter diameter.
