Accupro 95168845 Roughing End Mill 7/16 in 4 Flute Carbide

Product Description

The ACCUPRO 95168845 is a single-end roughing end mill designed for aggressive material removal in milling operations. Built from micrograin solid carbide with an AlTiN coating, it delivers heat resistance and wear life in demanding cutting environments. The 7/16-inch diameter tool features four flutes with a chipbreaker geometry that breaks chips into manageable segments, reducing cutting forces and heat buildup. With a 30-degree maximum helix angle and right-hand cutting and flute direction, it is suited for high-feed roughing passes on ferrous and hard materials. Licensed machinists and toolroom professionals are the primary users of this end mill.

This end mill is intended for use in CNC machining centers and manual milling machines where roughing cuts on steel, stainless steel, or similar hard materials are required. The chipbreaker profile makes it particularly effective in deep-cavity or slotting applications where chip evacuation is a common challenge. The 9/16-inch length of cut and 2-1/2-inch overall length fit standard tool holders sized for 7/16-inch shanks, making it a practical choice for tight-reach roughing work in production and job-shop environments.

Key Features

• Micrograin solid carbide construction for rigidity and wear resistance
• AlTiN coating provides thermal protection during high-speed cuts
• Chipbreaker geometry reduces cutting forces and improves chip control
• Four flutes balance material removal rate with chip clearance
• 30-degree maximum helix angle supports smooth, efficient cutting action
• Right-hand cut and right-hand flute direction for standard spindle operation

Compatibility

Designed as an OEM-style replacement or direct-use roughing end mill for standard 7/16-inch tool holders used in CNC and manual milling applications.

Installation Notes

This tool is installed by machinists in milling machine spindles or CNC tool holders rated for 7/16-inch shank diameters. Ensure the machine is fully de-energized and the spindle is locked before changing tooling. Verify runout and holder condition before use, as excessive runout will reduce tool life and cut quality. Follow shop safety protocols and machine manufacturer guidelines for RPM and feed-rate settings appropriate to the workpiece material.
