Accupro 12182558 Square End Mill 0.3937 in 4 Flute Carbide

Product Description

The ACCUPRO 12182558 is a solid carbide square end mill designed for precision milling operations in metalworking and machining environments. With a 0.3937-inch (10 mm) cutting diameter and 4 spiral flutes at a 40-degree helix angle, it delivers efficient chip evacuation and smooth cutting action across a range of ferrous and non-ferrous materials. The micrograin carbide construction provides the hardness and wear resistance needed for consistent performance in production and maintenance machining applications. Licensed machinists and CNC operators are the primary users of this tool.

This end mill is suited for slotting, profiling, and peripheral milling in standard vertical and horizontal milling setups as well as CNC machining centers. The 0.9843-inch (25 mm) length of cut accommodates typical depth requirements in die, mold, and general-purpose part machining. The regular-length configuration keeps deflection low, making it appropriate for finish passes and tight-tolerance work.

Key Features

• Solid micrograin carbide construction for hardness and extended tool life
• 40-degree helix angle promotes smooth cutting and effective chip evacuation
• Centercutting design allows plunge milling capability
• Right-hand cut and right-hand flute configuration for standard spindle setups
• Uncoated finish suitable for use with cutting fluid in a wide range of materials
• Spiral flute geometry with no chipbreaker for clean surface finishes

Compatibility

Designed as an OEM-style replacement or direct-use solid carbide square end mill for standard collet and end mill holders accepting a 10 mm (0.3937-inch) shank diameter in vertical mills and CNC machining centers.

Installation Notes

Installation is performed by qualified machinists or CNC operators. Ensure the spindle is fully stopped and the machine is in a safe, powered-down state before changing tooling. Verify collet or tool holder cleanliness and proper seating before tightening to prevent runout. Always confirm spindle direction and programmed feed and speed parameters before initiating a cut.
