Accupro 14796947 Square End Mill 0.028 in 4 Flute Altin

Product Description

The ACCUPRO 14796947 is a solid carbide square end mill designed for precision milling of ferrous and non-ferrous materials. With a 0.028 inch cutting diameter and a 0.084 inch length of cut, this tool is built for fine detail work and tight-tolerance slot milling, profiling, and contouring. The 4-flute, right-hand spiral geometry combined with a 30-degree helix angle promotes efficient chip evacuation and smooth surface finish. An AlTiN coating improves heat resistance and extends tool life in demanding cutting conditions. The micrograin carbide substrate adds toughness at small diameters where breakage risk is highest. Licensed machinists and toolroom professionals are the primary users of this tool.

This end mill is suited for small-diameter work found in mold and die machining, aerospace component finishing, and precision part production on CNC machining centers and manual mills. The 0.125 inch shank diameter fits standard collets and toolholders used in high-speed spindles. The single-end configuration and 1.5 inch overall length make it practical for short-reach applications where rigidity matters. Centercut capability allows for direct plunge entry without pre-drilling. Applications typically involve tight slot widths and fine feature detail where tool deflection must be minimized.

• Single-end design, 1.5 inch overall length, 0.125 inch shank diameter

Compatibility

Designed as an OEM-style replacement and standard tooling option for CNC machining centers and manual mills accepting a 0.125 inch round shank collet or toolholder. Part of the ACCUPRO ASQSC4-AT-CC-30H series.

Installation Notes

Installation is performed by machinists and CNC toolroom technicians. Secure the shank fully within the collet to the recommended grip depth before tightening to prevent pullout under cutting loads. Confirm spindle speed and feed rate are appropriate for the 0.028 inch diameter before initiating a cut, as micro-diameter end mills are sensitive to runout and excessive feed. Inspect the collet and toolholder for wear or contamination that could introduce runout prior to use.
