Accupro 14883543 Square End Mill 0.045 in 3 Flute Altin

Product Description

The ACCUPRO 14883543 is a solid carbide square end mill designed for precision milling operations in metalworking and machining applications. It features a 0.045-inch cutting diameter with a 0.225-inch length of cut (LOC) and a 3-flute, right-hand spiral geometry with a 30-degree helix angle. The micrograin carbide substrate and AlTiN (aluminum titanium nitride) coating provide hardness and heat resistance suited to high-speed cutting in ferrous and non-ferrous materials. The single-end configuration and 1/8-inch shank make it compatible with standard collet toolholding systems on CNC mills and manual milling machines.

This end mill is intended for finish milling, profiling, slotting, and contouring passes where small-diameter precision is required. Its centercutting capability allows plunge entry in addition to peripheral cutting. The AlTiN coating extends tool life in dry or minimal-lubrication cutting of hardened steels, stainless steel, and cast iron. The 0.045-inch diameter and 2.5-inch overall length (OAL) suit applications involving tight-tolerance features, thin walls, or restricted-clearance workpiece geometries common in mold and die, aerospace component, and precision part machining.

Key Features

• 0.045-inch cutting diameter with micrograin solid carbide substrate for rigidity at small diameters
• AlTiN coating for elevated heat resistance and extended tool life in hard and abrasive materials
• 3-flute design balances chip evacuation and cutting stability at this diameter range
• 30-degree right-hand helix promotes smooth chip flow and reduced cutting forces
• Centercutting geometry allows direct plunge entry without pre-drilling
• 1/8-inch shank diameter fits standard ER and precision collet systems

Compatibility

Designed for use in CNC machining centers and manual mills equipped with 1/8-inch collet toolholding. The 1/8-inch shank diameter is compatible with standard ER8, ER11, and similarly sized collet chucks accepting that shank size.

Installation Notes

Installation is performed by a machinist or CNC setup technician. Power down and lock out the spindle before inserting or removing tooling. Seat the shank fully into the collet to the recommended grip length before torquing the collet nut to the collet manufacturer's specification. At this small diameter, runout control is critical — verify total indicator runout (TIR) at the cutting tip before committing to a finishing pass.
