Accupro 95171867 5/8 in 3 Flute Roughing End Mill Zrn

Product Description

The ACCUPRO 95171867 is a single-end, solid carbide roughing finishing end mill designed for aggressive material removal and finish work in a single tool. Built from micrograin carbide and coated with zirconium nitride (ZrN), this end mill handles tough ferrous and non-ferrous materials while maintaining edge integrity across extended runs. It features a 5/8 inch mill diameter, a 3-flute right-hand cutting geometry, a 37-degree helix angle, and a chipbreaker profile that breaks chips to reduce heat buildup and recutting. Centercutting capability allows plunge entry without a pilot hole. Machinists and tool and die professionals use this type of end mill in CNC milling centers and manual knee mills.

This end mill is suited for roughing passes that require high metal removal rates, as well as finishing passes where surface quality is a priority. The chipbreaker geometry makes it particularly effective in deep-pocket milling where chip evacuation is critical. The 2 inch length of cut provides adequate reach for most standard cavity and profile work. The straight shank with a 5/8 inch diameter fits standard ER and side-lock toolholders common in production and job shop environments.

Key Features

• ZrN coating improves wear resistance and reduces heat transfer at the cutting edge
• Micrograin solid carbide substrate provides rigidity and resists deflection under load
• Chipbreaker flute geometry reduces chip packing in deep-pocket and slotting operations
• 37-degree helix angle promotes smooth cutting action and efficient chip evacuation
• Centercutting design enables direct plunge milling without pre-drilling
• Single-end construction with a straight 5/8 inch shank fits standard toolholders

Compatibility

Designed as an OEM-style replacement or direct-use roughing finishing end mill for CNC and manual milling applications requiring a 5/8 inch straight-shank toolholder.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer's toolholder torque and runout specifications. Ensure the spindle and toolholder are clean and free of chips before seating the shank. Verify runout with a dial indicator before initiating a cut, as excessive runout accelerates edge wear on carbide tooling. Always bring the spindle to a full stop before changing or inspecting the end mill.
