Accupro 120653 Roughing End Mill 1/4 in 3 Flute Solid Carbide

Product Description

The ACCUPRO 120653 is a single-end roughing end mill designed for high-volume material removal in milling applications. Built from submicron-grade solid carbide, it delivers the rigidity and wear resistance required for aggressive cutting passes. The 1/4 inch diameter tool features 3 spiral flutes with an integrated chipbreaker geometry that breaks chips into shorter segments, reducing heat buildup and improving chip evacuation at the cut. A high-helix flute design promotes efficient chip flow. This end mill is center-cutting and designed for right-hand cutting and flute direction. Licensed machinists and CNC operators typically run this tooling in machining centers and manual mills.

The 120653 suits roughing operations in ferrous and non-ferrous metals, plastics, and composites where material removal rate takes priority over surface finish. The 3/4 inch length of cut and 2-1/2 inch overall length make it appropriate for shallow-to-medium-depth pocketing, slotting, and profile roughing. The bright, uncoated finish makes it straightforward to inspect for wear between passes. The 1/4 inch shank with an h6 tolerance fits standard collet chucks and end mill holders without modification.

Key Features

• Submicron-grade solid carbide construction for extended tool life under heavy cutting loads
• Integrated chipbreaker geometry reduces chip length and lowers cutting forces during roughing passes
• High-helix spiral flute design promotes efficient chip evacuation from the cut zone
• Center-cutting capability allows plunge entry without a pre-drilled pilot hole
• Right-hand cut and flute direction; compatible with standard CNC and manual milling setups
• Bright uncoated finish simplifies visual wear inspection between operations

Compatibility

Designed as an OEM-style roughing end mill for use in standard 1/4 inch collet chucks and end mill holders on CNC machining centers and manual vertical mills.

Installation Notes

Installation is performed by qualified machinists or CNC operators. Confirm the spindle is fully stopped and the machine is locked out before changing tooling. Seat the 1/4 inch shank fully into a clean, undamaged collet or end mill holder and torque the retention mechanism to the tool holder manufacturer's specification. Verify runout with a dial indicator before beginning the cut, and confirm chip evacuation is adequate for the selected feed and speed parameters.
