Accupro 95171857 Roughing Finishing End Mill 1in 3-flute

Product Description

The ACCUPRO 95171857 is a solid carbide roughing and finishing end mill designed for aggressive material removal and fine finishing in a single tool. Built with a 1-inch diameter, 3-flute configuration, and a 37-degree helix angle, it delivers efficient chip evacuation and smooth cutting action. The chipbreaker geometry reduces cutting forces and controls chip size during heavy passes. A ZrN (zirconium nitride) coating provides enhanced wear resistance and lubricity, extending tool life in ferrous and non-ferrous applications. This end mill is suited for use by machinists and tool-and-die professionals operating CNC mills, VMCs, and manual knee mills.

This tool is intended for applications requiring both roughing and finishing passes without a tool change. The 2-inch length of cut accommodates moderate-depth pocketing, slotting, and peripheral milling. The straight shank with a 1-inch diameter fits standard ER, CAT, BT, and direct-fit toolholders commonly found in production and job-shop environments. Right-hand flute direction and right-hand cutting orientation are standard for conventional CNC milling operations. The single-end design and micrograin carbide substrate make it well-suited for harder workpiece materials and higher-speed machining programs.

Key Features

• Chipbreaker geometry reduces cutting forces and controls chip size during roughing passes
• ZrN coating improves wear resistance and reduces built-up edge in ferrous and non-ferrous materials
• 37-degree helix angle promotes smooth chip flow and stable cutting
• Micrograin solid carbide substrate provides rigidity and edge retention
• Center-cutting design allows plunge entry without pre-drilling
• Single-end, straight-shank construction for direct toolholder mounting

Compatibility

Designed as an OEM-style replacement or direct-use solid carbide end mill for standard 1-inch straight-shank toolholders used in CNC and manual milling applications.

Installation Notes

Installation should be performed by a qualified machinist or toolroom professional. Secure the straight shank in a properly sized collet or end mill holder, ensuring the shank is seated to the minimum insertion depth recommended for the holder. Verify runout with a dial indicator before beginning a production cut. Always power down and lock out the spindle before changing or adjusting tooling.
