Accupro 95168686 Square End Mill 1/8 in 6 Flute Solid Carbide

Product Description

The ACCUPRO 95168686 is a single-end, square-profile solid carbide end mill designed for precision material removal in CNC milling operations. It features a 1/8-inch cutting diameter, a 1/2-inch length of cut, and six flutes with a 25-degree right-hand helix angle. The micrograin carbide substrate delivers the hardness and wear resistance needed for demanding cutting cycles. An AlTiN coating adds thermal protection and surface hardness, extending tool life in high-temperature cutting environments. The variable index flute spacing reduces harmonic chatter, making this tool well suited for finishing passes and tight-tolerance work. Machinists and CNC operators in job shop and production environments are the primary users.

This end mill fits standard 1/8-inch collets and tool holders and is appropriate for milling operations on ferrous and non-ferrous metals, hardened steels, stainless, and superalloys where AlTiN coating performance is an advantage. Its regular-length geometry and compact 1-1/2-inch overall length make it a practical choice for short-reach slotting, profiling, and pocket milling where rigidity is a priority. It is centercutting, allowing plunge entry without a pre-drilled hole.

Key Features

• Six-flute design increases feed rate potential and improves surface finish compared to lower flute-count tools
• AlTiN coating provides high thermal resistance and hardness for extended tool life in difficult-to-machine materials
• Variable index flute spacing reduces vibration and chatter during cuts
• Micrograin solid carbide substrate delivers edge integrity under demanding chip loads
• Centercutting geometry supports direct plunge milling without a pilot hole
• Right-hand cut and right-hand spiral — standard orientation for conventional CNC milling spindles

Compatibility

Designed for use in standard 1/8-inch collet-style or precision tool holders on CNC machining centers and manual mills configured for right-hand rotation.

Installation Notes

Installation and tool changes must be performed with the machine spindle fully stopped and locked out per standard machine safety procedures. Seat the shank fully into the collet or tool holder and torque the retention nut to the tool holder manufacturer specification before running. Confirm runout with a dial indicator after seating to protect edge integrity on a six-flute fine-pitch tool. Follow the tooling manufacturer and machinery OEM guidelines for speeds, feeds, and depth of cut for the specific workpiece material.
