Accupro 95168624 Square End Mill 1 in 5 Flute Altin Carbide

Product Description

The ACCUPRO 95168624 is a solid carbide square end mill designed for high-performance milling in demanding machining environments. Built from micrograin carbide and coated with AlTiN (aluminum titanium nitride), it delivers excellent heat resistance and wear life in ferrous and high-temp alloy applications. The tool features a 1-inch cutting diameter, a 1-1/4-inch length of cut, and a 5-flute variable helix geometry that reduces harmonic vibration and improves chip evacuation. Right-hand cut and right-hand spiral flute direction are standard. It is centercutting and extended reach capable, making it suitable for slotting, profiling, and plunging operations. Machinists and CNC operators in job shops, aerospace, and general metalworking rely on this geometry for consistent finish and tool life.

This end mill is suited for use in CNC vertical and horizontal machining centers as well as manual knee mills with appropriate spindle speeds and feeds. The 1-inch shank diameter fits standard ER and side-lock toolholders. The 5-inch overall length and 2.375-inch neck length support extended reach applications where standard-length tools cannot access the workpiece. AlTiN coating makes it well matched for dry or minimal-lubrication cutting in steel, stainless, cast iron, and titanium alloys.

Key Features

• 1-inch cutting diameter with plus 0.000 / minus 0.002 inch diameter tolerance for predictable fit and finish
• 5-flute variable helix design reduces chatter and improves surface finish at higher feed rates
• AlTiN coating provides high-temperature oxidation resistance and extended tool life in ferrous and hard materials
• Micrograin solid carbide substrate for rigidity and edge retention
• Centercutting geometry allows plunge entry without a pre-drilled pilot hole
• Extended reach construction with 2.375-inch neck length for deep-pocket and hard-to-reach applications

Compatibility

Designed as an OEM-style replacement or direct selection for CNC machining center tooling requiring a 1-inch diameter, 5-flute square end mill with a 1-inch shank in standard ER collet, hydraulic, or side-lock toolholders.

Installation Notes

Installation and tool changes should be performed by a qualified machinist with the spindle at a full stop and machine power locked out per shop safety procedures. Ensure the toolholder bore is clean and free of chips before seating the shank; shank diameter tolerance is minus 0.0001 to minus 0.0004 inch for a controlled fit. Verify runout with a dial indicator after clamping before initiating a cut. Consult the machine manufacturer and tooling supplier for appropriate speeds, feeds, and depth-of-cut recommendations for the specific workpiece material.
