Accupro 12182711 Square End Mill 3/32 in 4 Flute Carbide

Product Description

The ACCUPRO 12182711 is a solid carbide square end mill designed for precision milling in ferrous and non-ferrous metals, hardened steels, and high-temperature alloys. Built from micrograin carbide stock, it carries an AlTiN finish that extends tool life under dry or semi-dry cutting conditions by reducing heat transfer into the substrate. The 4-flute, 30-degree spiral geometry provides a balance between chip evacuation and surface finish. At 0.0938 inches in diameter with a 3/16-inch length of cut, this is a stub-length tool engineered for rigidity in tight-clearance slotting and profiling operations. Machinists and tool-and-die tradespeople are the primary users.

This end mill is suited for CNC machining centers, vertical mills, and multi-axis platforms where small-diameter tooling is required. Typical applications include cavity milling, fine detail work in mold and die, and slotting operations in materials such as alloy steel, tool steel, and stainless. The stub-length configuration minimizes deflection at small diameters, making it appropriate for high-accuracy passes where tool runout must be controlled. The 1/8-inch shank seats in standard collets and shrink-fit holders.

Key Features

• Micrograin solid carbide construction for high wear resistance
• AlTiN coating for elevated heat resistance and extended tool life
• 4 flutes with 30-degree right-hand spiral for efficient chip flow
• Centercutting geometry allows plunge entry into the workpiece
• Stub length reduces deflection at 0.0938-inch diameter
• Right-hand cut and right-hand flute for standard spindle rotation

Compatibility

Designed as an OEM-style replacement or standard tooling selection for CNC machining centers and manual mills accepting a 1/8-inch straight shank collet or tool holder.

Installation Notes

Installation is performed by qualified machinists following shop tooling procedures. Ensure the spindle is fully stopped and the machine is in a safe state before changing tooling. Seat the shank fully into the collet or holder and torque the collet nut to the tool-holder manufacturer specification. Verify runout with a dial indicator before beginning a production cut, particularly at this diameter where small runout values have a proportionally large effect on tool life and surface finish.
