Accupro 12182713 Square End Mill 0.0984 in 4 Flute Carbide

Product Description

The ACCUPRO 12182713 is a solid carbide square end mill designed for precision milling in ferrous and non-ferrous materials. It features a 0.0984-inch (2.50 mm) mill diameter, a 0.1969-inch (5.00 mm) length of cut, and a stub-length body that minimizes deflection in tight-clearance setups. The TiCN coating improves surface hardness and wear resistance, extending tool life in abrasive cutting conditions. With four spiral flutes at a 30-degree helix angle and a micrograin carbide substrate, this end mill delivers clean, consistent cuts at small diameters. It is centercutting, allowing direct plunge entry into the workpiece.

This end mill is suited for finish milling, slotting, and profiling operations in CNC machining centers and manual mills. The stub-length geometry makes it a strong choice for high-speed, high-accuracy work where rigidity matters more than reach. Typical applications include die and mold work, precision component machining, and detail work on small-scale parts where a full-length tool would introduce excessive vibration or runout.

Key Features

• 0.0984-inch (2.50 mm) mill diameter with a tolerance of +0.000 / -0.002 inches
• 4 spiral flutes at 30-degree helix angle for efficient chip evacuation
• TiCN finish for improved wear resistance and surface hardness
• Solid micrograin carbide construction for rigidity at small diameters
• Centercutting design allows plunge milling without a pre-drilled pilot hole
• Right-hand cut, right-hand flute — standard CNC spindle orientation
• Stub-length body reduces deflection in precision milling applications

Compatibility

Designed as an OEM-style replacement or direct-fit tool for CNC machining centers and manual mills accepting a 3.00 mm (0.1181-inch) shank diameter with standard collet or end mill holder tooling.

Installation Notes

This tool is installed by machinists and CNC setup technicians using a compatible collet, shrink-fit holder, or end mill holder sized for the 3.00 mm shank. Confirm runout on the spindle and holder before cutting, as small-diameter carbide tools are sensitive to misalignment and can fracture under lateral load. Always verify spindle speed and feed rate against published cutting data for the workpiece material before engaging the cut. Carbide end mills at this diameter are brittle — avoid impact loading or interrupted cuts without appropriate feed adjustments.
