Accupro 125984 Roughing End Mill 3 Flute Solid Carbide

Product Description

The ACCUPRO 125984 is a single-end roughing end mill designed for aggressive material removal in milling operations. Built from submicron solid carbide with a bright uncoated finish, it features three flutes with an integrated chipbreaker geometry that breaks chips into manageable segments and reduces heat buildup during heavy cuts. The 0.015 inch corner radius provides edge reinforcement on the cutting tip. With a 3/16 inch mill diameter and 5/8 inch length of cut, this tool is suited for precision slotting, profiling, and roughing passes in ferrous and non-ferrous materials. It is installed by machinists and tool-and-die professionals working on CNC and manual milling equipment.

This end mill is intended for use in standard milling machine spindles and CNC machining centers that accept a 3/16 inch straight cylindrical shank. The right-hand cutting and right-hand flute direction make it compatible with conventional right-hand spindle rotation. The high helix spiral flute design promotes chip evacuation in deeper pocketing and slotting applications. The variable pitch configuration helps dampen vibration during high-feed roughing passes. This tool is a single-end design, meaning it is not reversible, and should be replaced when the cutting edge shows measurable wear.

Key Features

• Submicron solid carbide construction for wear resistance and edge retention
• Chipbreaker geometry reduces chip load and heat during roughing operations
• 0.015 inch corner radius reinforces the cutting edge and extends tool life
• Variable pitch flutes reduce harmonic vibration in high-feed applications
• High helix spiral flute design improves chip evacuation from the cut zone
• Centercutting capability allows plunge entry into workpiece material

Compatibility

Designed for use in CNC machining centers and manual milling machines with a 3/16 inch straight cylindrical shank holder and right-hand spindle rotation.

Installation Notes

This tool is installed by qualified machinists or tooling technicians. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Secure the shank firmly in a collet or end mill holder rated for the 3/16 inch shank diameter, observing the minimum insertion depth recommended for the holder type. Do not exceed the tool's rated depth of cut or feed rate, as solid carbide is brittle and susceptible to breakage under shock loading.
