Accupro 125978 Roughing Finishing End Mill 5/8 in 3 Flute

Product Description

The ACCUPRO 125978 is a single-end roughing finishing end mill designed for high-efficiency material removal in pocketing and profiling operations. Built from micrograin solid carbide, it delivers the rigidity and edge retention needed for demanding milling applications on a wide range of workpiece materials. The cutter measures 5/8 inch in diameter with a matching 5/8 inch shank diameter, a 1-5/8 inch length of cut, and a 3-1/2 inch overall length. The 37-degree helix angle promotes smooth chip evacuation and reduces cutting forces, making it well suited for both roughing passes and finishing work in a single tool.

This end mill is used in CNC machining centers and manual mills for pocketing, profiling, and slotting operations where a combination of stock removal rate and surface quality is required. The Series AL designation and bright uncoated finish make it a practical choice for general-purpose milling. It is a right-hand cutting, right-hand flute tool with three flutes, which balances chip clearance and tool rigidity. Machinists and tool-and-die professionals working in job shops, production facilities, and maintenance environments will find it applicable to ferrous and non-ferrous workpiece materials.

Key Features

• Micrograin solid carbide construction for superior hardness and wear resistance
• 37-degree helix angle promotes efficient chip evacuation during roughing and finishing cuts
• 5/8 inch diameter with 1-5/8 inch length of cut suitable for moderate-depth pocketing
• Bright uncoated finish compatible with a broad range of general-purpose milling applications
• Three-flute geometry balances chip clearance with cutting edge support
• Optimized for pocketing and profiling as noted in Series AL specifications

Compatibility

Designed as an OEM-style replacement and general-purpose solid carbide end mill for use in standard milling chucks, collet holders, and tool holders accepting a 5/8 inch shank diameter.

Installation Notes

Installation should be performed by a qualified machinist following safe tooling change procedures. Ensure the machine spindle is fully stopped and locked out before changing or seating the end mill in the holder. Confirm the shank is fully seated and the collet or chuck is torqued to the tool holder manufacturer specification before running. Note that this tool is not center-cutting and is not suitable for direct plunge entry into solid material.
