Accupro 95168283 Square End Mill 3/4 in 4-flute Altin Carbide

Product Description

The ACCUPRO 95168283 is a solid carbide square end mill designed for precision milling in demanding machining environments. Built from micrograin carbide and finished with an AlTiN (aluminum titanium nitride) coating, this tool handles high-heat applications and abrasive materials where standard coatings fall short. It features a 3/4 inch cutting diameter, a 1-5/8 inch length of cut, and a 4-inch overall length. The variable helix flute geometry reduces harmonic vibration and chatter during cutting, improving surface finish and extending tool life. Center-cutting capability allows direct plunge entry into workpieces without pre-drilling.

This end mill is suited for use in vertical and horizontal machining centers, CNC mills, and manual knee mills where a 3/4 inch shank holder is available. It performs well in ferrous materials, hardened steels, cast iron, and high-temp alloys where AlTiN coating delivers thermal resistance. Typical applications include profiling, slotting, and peripheral milling in job shop, tool and die, and production machining environments. Single-end configuration makes it a direct drop-in for standard end mill holders and collet chucks accepting 3/4 inch shanks.

Key Features

• Solid micrograin carbide construction for rigidity and wear resistance
• AlTiN coating provides high-temperature oxidation resistance for dry and hard milling
• Variable helix design reduces chatter and improves chip evacuation
• Center-cutting geometry allows plunge and ramp entry
• Right-hand cut and right-hand spiral flute configuration
• Tight shank diameter tolerance (+0.0001 / -0.0004 inches) for secure tool holding

Compatibility

Designed for use in standard 3/4 inch end mill holders, collet chucks, and shrink-fit tooling systems on CNC and manual milling machines.

Installation Notes

Installation and tool changes must be performed with the machine fully powered down and the spindle at a complete stop. Use a calibrated torque wrench and the appropriate holder wrench when seating the shank to avoid over-tightening. Inspect the shank and holder bore for chips or debris before installation. Machinists should follow shop-standard runout verification procedures after tooling changes to confirm concentricity before cutting.
