Accupro 120650 Roughing End Mill 3/16 in 3 Flute Solid Carbide

Product Description

The ACCUPRO 120650 is a single-end roughing end mill designed for aggressive material removal in milling operations. Built from submicron-grade solid carbide, it delivers the rigidity and wear resistance needed for high-demand cutting applications. The integrated chipbreaker geometry breaks chips into shorter segments, reducing heat buildup and improving chip evacuation in deeper passes. At 3/16 inch (0.1875 inch) in diameter with a 5/8 inch length of cut and a 2 inch overall length, this tool fits compact toolholders and tight-clearance setups. The bright, uncoated finish is suitable for use on a range of workpiece materials. Right-hand cutting and right-hand spiral fluting with a high helix style promote efficient chip flow and smooth cutting action.

This end mill is intended for use in CNC machining centers, manual knee mills, and similar machine tool setups where roughing passes are required before finish milling. Its 3/16 inch shank diameter with h6 tolerance shank fits standard collet chucks and end mill holders at that bore size. The centercutting design allows plunge entry into the workpiece. It is typically installed and operated by machinists and tool-and-die professionals working in job shops, production environments, or maintenance machining applications.

Key Features

• Submicron-grade solid carbide construction for high rigidity and wear resistance
• Chipbreaker geometry breaks chips to reduce heat and improve evacuation during heavy cuts
• Centercutting capable, allowing direct plunge entry without pre-drilling
• High helix, right-hand spiral flute design promotes efficient chip flow
• Bright uncoated finish suitable for a broad range of workpiece materials
• 3/16 inch shank with h6 tolerance for precise collet and holder fitment

Compatibility

Designed as an OEM-style replacement or direct-use roughing end mill compatible with standard 3/16 inch bore collet chucks and end mill holders used in CNC and manual milling machines.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer guidelines. Power down and lock out the spindle before loading or changing the tool. Seat the shank fully into the collet or holder to the minimum engagement depth recommended by the holder manufacturer before torquing the retention hardware. Verify runout with an indicator after clamping before beginning any cut.
