Accupro 12181235 Square End Mill 1/16 in 2 Flute Carbide

Product Description

The ACCUPRO 12181235 is a solid carbide square end mill designed for precision milling in metalworking and machining applications. With a 1/16 inch cutting diameter and a 3/16 inch length of cut, it handles tight-tolerance slotting, profiling, and contouring in confined areas. The AlTiN coating improves heat resistance and tool life in ferrous and hardened materials. Two spiral flutes at a 30-degree helix angle promote efficient chip evacuation while maintaining surface finish quality. This end mill is built for use in CNC machining centers and manual mills by machinists and tool-and-die professionals working in production or job-shop environments.

The 12181235 is suited for finish and semi-finish milling passes in steel, stainless steel, cast iron, and similar hard materials. Its 1/8 inch shank fits standard collets and end mill holders commonly found in both vertical and horizontal machining centers. The regular-length geometry and compact overall length of 1-1/2 inches make it appropriate for close-clearance work and small-feature machining where larger tooling cannot reach. The centercutting design allows plunge entry into the workpiece without pre-drilling.

Key Features

• Solid carbide micrograin construction for hardness and wear resistance
• AlTiN finish extends tool life in high-heat cutting applications
• 30-degree helix angle with spiral flutes for efficient chip removal
• Centercutting geometry permits direct plunge milling
• Right-hand cut and right-hand flute configuration for standard spindle rotation
• Mill diameter tolerance of +0.000 / -0.002 inches for consistent sizing

Compatibility

Designed as an OEM-style replacement or direct-use solid carbide end mill fitting any standard 1/8 inch collet or end mill holder in CNC or manual milling machines.

Installation Notes

Installation and tool changes should be performed by a qualified machinist with the spindle fully stopped and the machine in an energy-isolated state. Ensure the collet and holder are clean and free of debris before seating the shank to maintain runout tolerance. Torque the collet nut to the machine manufacturer's specification. Inspect the cutting edges under magnification before use and do not run the tool beyond its recommended cutting parameters for material grade and depth of cut.
