Accupro 95168411 Square End Mill 3/4 in 4 Flute Solid Carbide

Product Description

The ACCUPRO 95168411 is a solid carbide square end mill designed for precision milling in demanding metal-cutting applications. With a 3/4 inch cutting diameter, 1-5/8 inch length of cut, and a 37-degree helix angle, this tool delivers efficient chip evacuation and stable cutting performance. The AlTiN (aluminum titanium nitride) coating provides high heat resistance and extended tool life when cutting hardened steels, stainless, and high-temperature alloys. Micrograin carbide construction supports tighter tolerances and sharper edge retention compared to standard carbide grades. This end mill is sold as a single-end tool and is intended for use by machinists and tool-and-die professionals in CNC and manual milling operations.

This end mill is well-suited for peripheral and slot milling in ferrous and non-ferrous metals in both job shop and production environments. The 4-flute configuration supports higher feed rates and improved surface finish on finishing passes. The variable index geometry reduces harmonic vibration during cutting, making it appropriate for applications where chatter control is critical. The 3/4 inch shank diameter provides solid tool holding with standard ER, CAT, or BT toolholders common in vertical and horizontal machining centers.

Key Features

• AlTiN coating for high heat resistance and extended tool life in ferrous materials
• Micrograin solid carbide substrate for sharp, durable cutting edges
• 37-degree helix angle promotes efficient chip evacuation and smooth cutting action
• Variable index flute spacing reduces vibration and chatter during milling
• Centercutting design allows plunge entry into workpiece material
• Right-hand cut and right-hand spiral flute configuration for standard CNC spindle compatibility

Compatibility

Designed as a direct-fit replacement or standard-use solid carbide square end mill for CNC machining centers and manual milling machines accepting a 3/4 inch shank diameter toolholder.

Installation Notes

Installation should be performed by a qualified machinist. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Seat the shank fully into the toolholder collet or end mill holder and torque the retention mechanism according to the toolholder manufacturer specifications. Confirm runout with a dial indicator before beginning cuts to protect both the tool and the workpiece.
