Accupro 95168385 Square End Mill 1/8 in 5 Flute Altin Carbide

Product Description

The ACCUPRO 95168385 is a solid carbide square end mill designed for precision milling operations in ferrous and non-ferrous materials. It features a 1/8 inch diameter with a 3/4 inch length of cut and a 3 inch overall length. The five-flute geometry combined with a variable helix design reduces harmonic vibration, improves chip evacuation, and supports higher feed rates compared to standard fixed-helix end mills. An AlTiN coating provides heat resistance and extended tool life in hardened steels and high-temperature alloys. This tool is used by machinists and CNC operators in job shops, production floors, and toolrooms.

This end mill is suited for finish and semi-finish milling of slots, pockets, and profiles in materials that generate significant heat at the cutting zone. The variable helix construction makes it particularly effective in difficult-to-machine alloys, stainless steel, and tool steel where surface finish and edge life are critical. The single-end, right-hand cutting configuration is the standard setup for conventional vertical machining centers and CNC mills. The 1/8 inch shank diameter matches the cutter diameter, making it compatible with standard ER collet systems and precision end mill holders.

Key Features

• 5-flute variable helix geometry reduces chatter and improves surface finish
• AlTiN coating for heat resistance in hardened and high-temperature materials
• Solid carbide micrograin substrate for rigidity and edge retention
• Center-cutting design allows plunge entry
• Right-hand cut and right-hand flute spiral for standard CNC mill setups
• Long-length designation with 3/4 inch LOC in a 3 inch OAL profile

Compatibility

Designed as an OEM-style replacement and standard tooling option for CNC vertical machining centers and manual mills accepting 1/8 inch shank end mills via ER collet chucks or precision end mill holders.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the machine spindle is fully stopped and locked out before changing tooling. Seat the shank fully into the collet or holder to the recommended grip length before torquing the retention nut. Verify runout with a dial indicator after installation, as excessive runout will accelerate wear on small-diameter carbide tools.
