Accupro 12181830 Square End Mill 3/4 in 2 Flute Carbide

Product Description

The ACCUPRO 12181830 is a solid carbide square end mill designed for precision milling operations in metal, composites, and hard plastics. Built from micrograin carbide, it offers the rigidity and edge retention needed for demanding cuts. The 3/4-inch diameter cutter runs a 40-degree helix spiral flute geometry, which promotes efficient chip evacuation and reduces cutting forces. With a 2-inch length of cut and a 6-inch overall length, this is a long-length configuration suited for extended-reach applications where standard-length tools fall short. It is centercutting, meaning it can plunge directly into the workpiece. Machinists and tooling professionals in job shops, manufacturing facilities, and maintenance operations are the primary users.

This end mill is appropriate for general-purpose milling on CNC machining centers and manual mills. The long overall length of 6 inches makes it well-suited for deep-pocket milling, tall workpiece fixturing, and applications where tool holder clearance requires additional reach. The 2-flute configuration is commonly used for slotting and milling softer ferrous and non-ferrous materials where chip clearance is a priority. The right-hand cut and right-hand flute direction follow standard convention for the majority of vertical and horizontal milling setups.

Key Features

• Micrograin solid carbide construction for high hardness and edge retention
• 40-degree helix spiral flute promotes aggressive chip evacuation
• Centercutting design allows direct plunge entry into the workpiece
• Long-length configuration with 6-inch OAL supports extended-reach applications
• Uncoated finish — suitable for use with cutting fluids on a wide range of materials
• Right-hand cut and right-hand flute, compatible with standard spindle rotation

Compatibility

Designed as an OEM-style replacement or direct tooling selection for CNC machining centers and manual milling machines accepting a 3/4-inch straight shank tool holder, collet, or end mill adapter.

Installation Notes

Installation should be performed by a qualified machinist or toolroom professional. Ensure the machine spindle is fully stopped and locked out before inserting or removing the end mill. Seat the shank fully into the collet or tool holder to the recommended grip length and torque the retention mechanism per the tool holder manufacturer specifications. Verify runout with a dial indicator before initiating a cut, as excessive runout accelerates edge wear and reduces surface finish quality.
