Accupro 14899832 Square End Mill 0.07in 4 Flute Carbide

Product Description

The ACCUPRO 14899832 is a solid carbide square end mill designed for precision milling operations in metal, composite, and hard-material applications. With a 0.07-inch cutting diameter and a 0.21-inch length of cut, this is a small-diameter tool built for tight-tolerance work in slots, pockets, and profiling passes. The four-flute, right-hand spiral configuration with a 30-degree helix angle promotes chip evacuation and surface finish quality. The micrograin carbide substrate provides edge retention and rigidity at small diameters where tool deflection and breakage are primary concerns. It is a single-end, centercutting tool suitable for plunge entry and peripheral milling.

This end mill is suited for job shop machinists, tool-and-die work, mold making, and precision part manufacturing where small-feature milling is required. The extended-reach design, with a 0.5-inch reach length, allows access to recessed features and stepped surfaces that shorter tools cannot reach. The bright, uncoated finish makes it appropriate for non-ferrous metals, plastics, and other materials where coatings could affect dimensional transfer or chip adhesion. The 1/8-inch shank fits standard collet systems commonly found on CNC machining centers and manual mills.

Key Features

• 0.07-inch cutting diameter with tight tolerance: plus 0.0000 / minus 0.0010 inches
• Four flutes with right-hand spiral and 30-degree helix angle for efficient chip flow
• Micrograin solid carbide construction for rigidity and edge retention at small diameters
• Centercutting design allows direct plunge entry
• Extended reach of 0.5 inches for access to recessed features
• Bright, uncoated finish suitable for non-ferrous and abrasive materials

Compatibility

Designed as an OEM-style replacement or direct-fit tool for standard 1/8-inch collet systems on CNC machining centers, manual mills, and high-speed spindle units accepting right-hand cutting end mills.

Installation Notes

Installation is performed by a machinist or CNC setup technician. Ensure the machine spindle is fully stopped and de-energized before inserting or removing the tool from the collet. Verify collet bore size matches the 0.125-inch shank diameter and that collet and holder are clean and free of runout-inducing debris. Do not over-torque the collet nut, as this can induce shank deformation on small-diameter tools.
