Accupro 12277114 Square End Mill 0.105 in 4 Flute Carbide

Product Description

The ACCUPRO 12277114 is a solid carbide square end mill designed for precision milling operations in metal, composite, and engineering-plastic workpieces. With a 0.105-inch cutting diameter and a 0.158-inch length of cut (LOC), this tool handles slotting, profiling, and light pocketing in tight geometries. The 4-flute configuration and 30-degree helix angle promote efficient chip evacuation and smooth surface finishes at higher feed rates. Micrograin carbide construction delivers edge retention and rigidity in the small-diameter range where high-speed steel tools typically fail. The bright, uncoated finish suits general-purpose applications where coating is not required.

This end mill is suited for CNC machining centers, high-speed VMCs, and manual knee mills running close-tolerance detail work. The 0.125-inch shank diameter and 1.5-inch overall length (OAL) allow use in standard 1/8-inch collets and small-bore tool holders. It is a single-end, right-hand cut, right-hand spiral tool appropriate for conventional and climb milling of ferrous and non-ferrous materials. Machinists, toolmakers, and CNC operators running fine-feature or mold-detail work will find this tool fits common small-diameter tooling setups without special adapters.

Key Features

• 0.105-inch cutting diameter with mill diameter tolerance of +0.0000 / -0.0010 inches for consistent sizing
• Micrograin solid carbide construction for rigidity and edge retention at small diameters
• 4 flutes with 30-degree right-hand helix for efficient chip flow and smooth finishes
• Centercutting design allows plunge entry as well as lateral cutting passes
• Bright/uncoated finish suitable for general-purpose ferrous and non-ferrous milling
• 1/8-inch (0.125-inch) shank diameter fits standard small-bore collets without special tooling

Compatibility

Designed as a direct-fit replacement or standard tooling option for any CNC or manual milling setup using 1/8-inch collets or tool holders accepting a 0.125-inch shank diameter.

Installation Notes

Installation is performed by qualified machinists or CNC operators. Ensure the spindle is fully stopped and locked before inserting or removing the tool from the collet. Verify collet condition and runout before tightening, as small-diameter carbide tools are sensitive to even minor runout at the spindle. Follow your machine manufacturer and shop safety guidelines for speeds, feeds, and coolant when operating solid carbide end mills.
