Accupro 12180766 Square End Mill 1 in 5 Flute Solid Carbide

Product Description

The ACCUPRO 12180766 is a single-end square end mill designed for precision milling in metal and hard-material applications. Built from micrograin solid carbide with an AlTiN finish, it delivers consistent performance in demanding cutting conditions. The tool features a 1 inch cutting diameter, a 3.375 inch length of cut, and a 6 inch overall length. Five spiral flutes with a 40-degree helix angle and variable index geometry help reduce chatter and improve chip evacuation. Centercutting capability allows plunge entry as well as conventional peripheral milling. Licensed machinists and CNC operators are the typical end users for tooling of this class.

This end mill suits a wide range of milling operations including slotting, profiling, and full-width cutting in ferrous and non-ferrous metals. The AlTiN coating performs well at elevated temperatures, making it appropriate for dry or minimally lubricated cutting in steel, stainless steel, and high-temperature alloys. The 1 inch shank diameter fits standard ER and side-lock holders common to CNC machining centers and manual knee mills. Its extended 3.375 inch length of cut makes it well suited to deep-pocket and deep-slot applications where shorter tooling cannot reach.

Key Features

• Micrograin solid carbide construction for rigidity and wear resistance
• AlTiN coating supports high-temperature dry and semi-dry cutting
• 5 spiral flutes with 40-degree helix angle for efficient chip evacuation
• Variable index flute spacing reduces harmonic chatter during aggressive passes
• Centercutting design allows direct plunge milling entry
• Right-hand cut and right-hand flute configuration for standard spindle operation

Compatibility

Designed as a direct-fit replacement or standard addition for CNC machining centers and manual mills accepting a 1 inch straight shank with ER collet chucks, milling chucks, or side-lock holders.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. The shank must be fully seated in the tool holder to the recommended engagement depth before tightening to prevent pullout under cutting loads. Verify runout with a dial indicator after installation, as excessive runout will accelerate wear and degrade surface finish. Always power down and lock out the spindle before changing tooling.
