Ingersoll Cutting Tools 3012023 Square-shoulder End Mill

Product Description

The INGERSOLL CUTTING TOOLS 3012023 is a 2-flute indexable square-shoulder end mill designed for facing, shouldering, slotting, and ramping operations in general-purpose machining. Built on the 12J1E cutter series, it accepts two AOMT 1805.. screw-held inserts with a positive rake geometry for efficient cutting across universal workpiece materials. The steel body features a 1-inch Weldon flat shank for secure tool holding and includes through-coolant capability to manage heat and chip evacuation at the cutting zone. Overall length is 4 inches with a usable length of 1.5 inches. Machinists and toolroom technicians working on CNC mills and machining centers are the primary users.

This end mill suits general-purpose milling in job shops, production shops, and maintenance machining environments. Its 1-inch cutting diameter and 0.66-inch maximum depth of cut make it well-suited for moderate-width shoulder milling and face milling passes on ferrous and non-ferrous materials. The maximum ramping angle of 6 degrees allows helical or linear ramp entry into the workpiece without a pre-drilled pilot hole. Right-hand cut geometry is standard. The through-coolant feature makes it appropriate for applications where chip buildup or elevated cutting temperatures are concerns.

Key Features

• 1-inch cutting diameter with 0.66-inch maximum depth of cut for square-shoulder profiling
• Accepts two AOMT 1805.. indexable inserts secured by screw clamping
• Through-coolant delivery for heat management and chip evacuation
• Maximum 6-degree ramping angle supports ramp-in entry strategies
• Positive rake insert geometry reduces cutting forces on universal workpiece materials
• Weldon flat shank provides positive drive and slip resistance in standard end mill holders

Compatibility

Compatible with AOMT 1805.. series indexable inserts. Designed for use in standard 1-inch Weldon flat end mill holders on CNC vertical and horizontal machining centers.

Installation Notes

Installation is performed by machining tool setup technicians or CNC operators. Ensure the machine spindle is fully stopped and the tool changer is in a safe state before mounting or removing the tool body. Seat the Weldon flat shank fully into the holder and tighten the set screw against the flat to rated holder torque specifications per the holder manufacturer. Inspect inserts for wear or chipping before each use and index or replace as needed following the insert manufacturer's handling guidance.
