Accupro 95171372 Ball End Mill 4mm 2 Flute Solid Carbide Zrn

Product Description

The ACCUPRO 95171372 is a single-end ball end mill designed for precision milling operations in ferrous and non-ferrous materials. Built from micrograin solid carbide, it delivers the rigidity and edge retention needed for demanding cutting applications. The tool features a 4.00 mm cutting diameter, a 12.00 mm length of cut, and a 45-degree helix angle that promotes efficient chip evacuation and reduces cutting forces. A zirconium nitride (ZrN) coating adds surface hardness and heat resistance, extending tool life in high-cycle production environments. This end mill is intended for use by machinists and tooling specialists working in CNC machining centers.

This end mill is suited for finishing and semi-finishing passes in mold work, die making, and general precision machining where a ball-nose profile is required. The 4.00 mm shank diameter matches the cutting diameter, making it compatible with standard ER collet systems and precision shrink-fit holders commonly found in vertical and horizontal machining centers. The right-hand cut and right-hand spiral flute geometry support conventional and climb milling strategies.

Key Features

• Micrograin solid carbide construction for superior hardness and wear resistance
• ZrN coating enhances surface hardness and thermal resistance during high-speed cutting
• 45-degree helix angle promotes efficient chip flow and reduces cutting pressure
• 4.00 mm ball nose profile for contoured surface milling and finishing passes
• Right-hand cutting direction with spiral flute geometry for consistent chip evacuation
• Single-end design with 50.00 mm overall length for reach in standard setups

Compatibility

Designed as a direct-fit tooling solution for CNC machining centers accepting 4.00 mm shank end mills via ER collet chucks, shrink-fit holders, or equivalent precision toolholding systems.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Ensure the machine spindle is fully stopped and the tool changer or spindle is locked out before inserting or removing the end mill. Use a calibrated torque wrench on collet nuts and verify runout with a dial indicator before beginning a cut. Do not exceed the tool manufacturer's recommended speed and feed parameters for the workpiece material and coating type.
