Accupro 95171402 End Mill 4mm 3 Flute Solid Carbide Zrn

Product Description

The ACCUPRO 95171402 is a solid carbide roughing and finishing end mill designed for aggressive material removal and fine finishing in a single tool. With a 4 mm cutting diameter, 3-flute configuration, and a 37-degree helix angle, this end mill delivers efficient chip evacuation and smooth cutting action. The zirconium nitride (ZrN) coating reduces friction and extends tool life in demanding machining applications. The micrograin carbide substrate provides the hardness and edge retention needed for precision work in tight-tolerance environments. Installed by machinists and CNC operators in production and job-shop settings.

This end mill is suited for milling applications requiring both stock removal and finish passes without a tool change. The square end geometry supports shoulder milling, slotting, and profiling operations. With a 12 mm length of cut and 50 mm overall length, it fits standard toolholding systems used in vertical machining centers and CNC mills. The centercutting design allows plunge entry. Right-hand flute direction and right-hand cutting orientation are standard for conventional CNC setups.

Key Features

• 4 mm cutting diameter with matching 4 mm straight shank for direct collet or toolholder fitment
• 3-flute design balances chip clearance with cutting edge contact for roughing and finishing
• 37-degree helix angle promotes smooth cutting action and efficient chip evacuation
• ZrN coating reduces tool wear and thermal buildup during extended cuts
• Micrograin solid carbide construction for high hardness and dimensional stability
• Centercutting square end supports plunge milling and full-profile finishing

Compatibility

Designed as an OEM-style replacement and standard tooling option for CNC vertical machining centers and manual mills accepting 4 mm straight shank end mills in compatible collet or toolholding systems.

Installation Notes

Installation is performed by a machinist or CNC setup technician. Ensure the machine spindle is fully stopped and the tool changer or spindle is locked out before inserting or removing the end mill. Seat the shank fully in the collet or toolholder and torque the retention mechanism per the toolholder manufacturer specification. Verify runout with a dial indicator before initiating a cutting program.
