Accupro 12185119 Square End Mill 3/16 in 4 Flute Carbide

Product Description

The ACCUPRO 12185119 is a solid carbide square end mill designed for precision milling in metal, composites, and engineering plastics. The tool features a 3/16 inch cutting diameter, a 1/2 inch length of cut, and a 3/8 inch shank diameter, with a 3 inch overall length. Built from micrograin solid carbide, it delivers the rigidity and edge retention required for demanding material removal. The 4-flute, 40-degree helix spiral geometry promotes efficient chip evacuation while maintaining a smooth surface finish. This is a double-end, uncoated configuration intended for machinists and toolroom professionals working on CNC mills and manual milling machines.

This end mill is suited for general-purpose milling operations in job shop, production machining, and toolroom environments. Its centercutting capability allows plunge entry directly into workpiece material, making it viable for slotting, profiling, and pocketing operations. The right-hand cut and right-hand flute orientation are standard for conventional and climb milling on vertical machining centers. The regular-length geometry fits a broad range of fixture setups where extended reach is not required.

Key Features

• Micrograin solid carbide construction for superior hardness and edge retention
• 4-flute spiral design with 40-degree helix angle for improved chip flow and surface finish
• Centercutting geometry enables direct plunge entry into workpiece material
• Double-end configuration extends usable tool life per unit
• Uncoated finish suitable for use with cutting fluids across a range of materials
• Right-hand cut and right-hand flute for standard CNC and manual milling setups

Compatibility

Designed as a standard shank replacement end mill for CNC vertical machining centers, knee mills, and toolroom milling machines accepting a 3/8 inch collet or end mill holder.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Secure the 3/8 inch shank in a properly sized collet, end mill holder, or set-screw adapter, and verify runout before engaging the cut. Ensure the machine spindle is fully stopped before changing tooling. Follow shop-standard speeds and feeds for the specific workpiece material and apply cutting fluid as appropriate for the material and operation.
