Accupro 95168824 Square End Mill 5/8 in 5 Flute Altin Carbide

Product Description

The ACCUPRO 95168824 is a solid carbide square end mill designed for high-performance milling in demanding machining environments. With a 5/8-inch (0.6250-inch) mill diameter, five flutes, and an AlTiN (Aluminum Titanium Nitride) coating, this tool delivers efficient material removal and extended tool life in hard and abrasive workpiece materials. The variable helix geometry reduces harmonic vibration during cutting, improving surface finish and tool stability. It is centercutting, enabling plunge milling operations. Machinists and CNC operators in job shops, production facilities, and toolrooms use this end mill for profiling, slotting, and finishing cuts in ferrous and non-ferrous alloys.

This end mill is suited for use in vertical and horizontal CNC machining centers as well as manual knee mills where the spindle speed and rigidity can support solid carbide tooling. The extended reach configuration, with a neck length of 2.375 inches and an overall length of 5 inches, makes it appropriate for deep-pocket and hard-to-reach milling applications. The 3/4-inch length of cut (with a range of 0.700 to 0.800 inches) handles moderate-depth passes, and the 5/8-inch shank diameter suits standard ER and end mill holders commonly found in production setups. Right-hand cutting and right-hand spiral flute direction are standard for conventional CNC operation.

Key Features

• Solid carbide micrograin construction for hardness and wear resistance at elevated cutting temperatures
• AlTiN coating improves heat resistance and reduces friction in ferrous and hard alloy machining
• Variable helix flute geometry minimizes chatter and improves surface finish at higher feed rates
• Centercutting design allows direct plunge entry into the workpiece
• Extended reach with 2.375-inch neck length for deep-pocket and restricted-access milling
• Five-flute configuration supports higher feed rates compared to standard three- or four-flute end mills

Compatibility

Designed for use in standard 5/8-inch end mill holders, ER collet chucks, and shrink-fit holders on CNC vertical and horizontal machining centers. Shank diameter tolerance of -0.0001 to -0.0004 inches ensures proper fit in precision toolholding systems.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the tool holder is clean and free of chips or burrs before seating the shank to the recommended gauge line. Verify spindle and holder runout with a dial indicator before production use, as excessive runout reduces tool life and surface quality. Follow the machine tool manufacturer and tooling manufacturer guidelines for speeds, feeds, and depth of cut for the specific workpiece material.
