Tungaloy 6861287 Square-shoulder Face Mill 2 in Dorec

Product Description

The TUNGALOY 6861287 is an indexable square-shoulder face mill designed for precision milling operations in metal cutting applications. Built to a 90-degree lead angle with a positive rake geometry, this cutter accepts six LQMU 1107 inserts secured by a clamp and screw holding method. The 2-inch cutting diameter and 0.354-inch maximum depth of cut make it well suited for shoulder milling and face milling passes where square wall definition is required. Through-coolant capability supports chip evacuation and tool life in demanding cutting conditions. Licensed machinists and CNC mill operators working to ISO standards will find this cutter a direct-fit solution for DoRec series tooling setups.

This face mill is intended for use on CNC machining centers and manual knee mills equipped with arbor-style toolholding. The 3/4-inch arbor hole diameter fits standard arbors common in both job shop and production environments. The DoRec series platform is engineered for square-shoulder profiling, step milling, and face milling of ferrous and non-ferrous materials. With six cutting positions and through-coolant delivery, it supports consistent performance in both roughing and semi-finishing passes where perpendicular wall accuracy is critical.

Key Features

• 2-inch cutting diameter with 0.354-inch maximum depth of cut for square-shoulder milling
• 90-degree lead angle produces true square walls on workpiece shoulders
• Accepts six LQMU 1107 inserts with clamp and screw retention for secure cutting
• Through-coolant design supports chip flushing and insert temperature management
• Positive rake geometry reduces cutting forces for stable, chatter-resistant performance
• Conforms to ISO standards for insert and tooling interchangeability

Compatibility

Designed for use with LQMU 1107 series inserts as part of the TUNGALOY DoRec square-shoulder milling system. Fits arbors with a 3/4-inch arbor hole diameter.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Ensure the machine spindle is fully stopped and locked out before mounting or removing the cutter from the arbor. Confirm insert seating and clamp screw torque according to the toolholder documentation before initiating a cut. Verify through-coolant passages are clear and that coolant pressure meets machine specifications prior to operation.
