Accupro 95171858 Roughing Finishing End Mill 3/8 in

Product Description

The ACCUPRO 95171858 is a solid carbide roughing finishing end mill designed for high-efficiency material removal and finish work in a single tool. Built with a chipbreaker geometry and a 37-degree helix angle, it breaks chips aggressively while maintaining a clean cutting edge. The 3/8 inch diameter with a micrograin carbide substrate gives it strong wear resistance in ferrous and non-ferrous applications. A ZrN (zirconium nitride) coating extends tool life and reduces built-up edge at elevated cutting speeds. This is a single-end, stub-length tool intended for machinists and toolroom professionals running CNC mills or manual knee mills.

This end mill is suited for roughing and finishing passes in one setup, reducing tool changes on the floor. The stub length and straight 3/8 inch shank make it well-matched to tight setups where overhang needs to be minimized. Right-hand flute direction and right-hand cutting orientation are standard for conventional CNC milling operations. The centercutting capability allows plunge entry directly into the workpiece. Typical applications include slot milling, profiling, and pocket work in steel, stainless, aluminum, and similar materials.

Key Features

• Chipbreaker geometry promotes efficient chip evacuation and reduces recutting in deep cuts
• ZrN coating improves surface hardness and heat resistance for extended tool life
• Micrograin solid carbide substrate provides rigidity and edge retention
• 37-degree helix angle balances cutting force and surface finish performance
• Centercutting design allows direct plunge entry without pre-drilling
• Stub-length construction reduces deflection in close-clearance setups

Compatibility

Designed as an OEM-style replacement or direct-use solid carbide end mill for standard 3/8 inch collet or end mill holders used in CNC machining centers and manual mills.

Installation Notes

Installation is performed by qualified machinists familiar with tool holding systems and feeds-and-speeds selection. Ensure the holder and collet are clean and free of debris before seating the shank. Verify runout with a dial indicator after tightening to minimize premature edge wear. Do not exceed the tool manufacturer or machine rated RPM for the selected diameter and material combination.
