Accupro 12181798 Square End Mill 0.5 in 2 Flute Solid Carbide

Product Description

The ACCUPRO 12181798 is a solid carbide square end mill designed for precision milling in metalworking and machining applications. Built from micrograin solid carbide with a TiCN (titanium carbonitride) finish, this tool delivers hard, wear-resistant cutting performance across a range of ferrous and non-ferrous materials. The 0.5 inch diameter cutter features 2 spiral flutes with a 40-degree helix angle for efficient chip evacuation and smooth cutting action. With an extra-long overall length of 3.5 inches and a 1.5 inch length of cut, this end mill is suited for deep-reach milling operations where standard-length tools fall short. Machinists and CNC operators in job shops and production environments are the primary users.

This end mill is used in milling machines and CNC machining centers for slotting, profiling, and peripheral milling operations. The centercutting geometry allows plunge cutting directly into the workpiece. The right-hand cut and right-hand flute configuration is the standard for conventional milling setups. The extra-long configuration makes it appropriate for machining deep pockets, tall workpiece features, or setups requiring extended reach past fixtures or clamps. The 0.5 inch shank diameter fits standard ER collet chucks, end mill holders, and set-screw-style tool holders designed for that shank size.

Key Features

• Micrograin solid carbide construction for rigidity and wear resistance
• TiCN finish for improved surface hardness and tool life
• 40-degree helix angle promotes smooth cutting and efficient chip evacuation
• Centercutting design allows direct plunge entry into the workpiece
• Extra-long 3.5 inch OAL for deep-reach milling applications
• Right-hand cut and right-hand flute for standard milling machine compatibility

Compatibility

Designed as an OEM-style solid carbide square end mill for use in standard 0.5 inch end mill holders, ER collet chucks, and set-screw tool holders on conventional and CNC milling machines.

Installation Notes

Installation should be performed by a qualified machinist following shop safety protocols. Ensure the machine spindle is fully stopped and the tool holder is clean and free of chips before seating the shank. Verify runout after installation using a dial indicator before committing to a full cut. Consult the machine manufacturer torque specifications for the tool holder being used.
