Accupro 12182459 Square End Mill 0.25 in 4 Flute Solid Carbide

Product Description

The ACCUPRO 12182459 is a solid carbide square end mill designed for precision milling operations across a range of ferrous and non-ferrous materials. Built from micrograin solid carbide, this tool delivers the rigidity and edge retention needed for consistent, accurate cuts. The TiCN coating reduces friction and extends tool life under demanding cutting conditions. With a 40-degree helix angle and four spiral flutes, the 12182459 promotes efficient chip evacuation and smooth surface finishes. It is centercutting capable, allowing direct plunge entry into workpieces. This end mill is intended for use by machinists and CNC operators working in production or toolroom environments.

This end mill is suited for milling slots, pockets, profiles, and contours in a wide range of materials including steel, stainless steel, cast iron, and aluminum alloys. The regular-length geometry makes it a practical general-purpose choice for vertical machining centers, CNC mills, and manual knee mills. Right-hand cut and right-hand flute configuration make it compatible with standard spindle rotation. It is sold individually and is appropriate for shops requiring consistent performance on precision workholding setups.

Key Features

• Micrograin solid carbide construction for rigidity and edge retention
• TiCN finish reduces friction and extends tool life in demanding applications
• 40-degree helix angle with spiral flutes for efficient chip evacuation
• Centercutting design allows direct plunge entry into the workpiece
• Right-hand cut and right-hand flute for standard spindle compatibility
• Regular length geometry suitable for general-purpose milling operations

Compatibility

Designed as a standard shank end mill for use in 0.25 inch collets, end mill holders, and shrink-fit toolholders on CNC machining centers and manual mills with right-hand spindle rotation.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the machine spindle is fully stopped and locked out before loading or removing the tool. Seat the shank to the recommended minimum insertion depth per the toolholder manufacturer specification to maintain rigidity and runout tolerances. Verify collet condition and holder concentricity before use, as excessive runout will accelerate wear and degrade surface finish.
