Accupro 12182441 Square End Mill 13/64 in 4 Flute Carbide

Product Description

The ACCUPRO 12182441 is a solid carbide square end mill designed for precision milling in metal and hard-material applications. With a 13/64 inch (0.2031 inch) cutting diameter, a 4-flute spiral design, and a 40-degree helix angle, this tool delivers efficient chip evacuation and a smooth finish in ferrous and non-ferrous materials. The AlTiN coating provides heat resistance and extended tool life at elevated cutting speeds. A 1/4 inch shank diameter and 2-1/2 inch overall length make it compatible with standard collet and end mill holders used in CNC mills and manual knee mills alike. Micrograin carbide construction gives the tool dimensional stability and edge retention in demanding cuts.

This end mill is suited for slot milling, peripheral milling, and plunge operations in tool rooms, production shops, and maintenance environments. Its centercutting geometry allows direct plunge entry into the workpiece without a pre-drilled hole. The right-hand cut and right-hand flute configuration is the standard orientation for conventional vertical milling setups. Regular length classification makes it a straightforward drop-in for general-purpose work where extended reach is not required.

Key Features

• Solid micrograin carbide construction for edge retention and rigidity
• AlTiN finish for heat resistance and extended tool life at high cutting speeds
• 40-degree helix angle promotes efficient chip evacuation and reduced chatter
• Centercutting design allows direct plunge milling without pre-drilling
• 4-flute spiral configuration balances material removal rate with surface finish
• Right-hand cut and right-hand flute for standard CNC and manual milling setups

Compatibility

Designed as an OEM-style replacement or standard tooling selection for CNC and manual vertical milling machines accepting a 1/4 inch shank end mill holder or collet.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Ensure the milling machine spindle is fully stopped and locked before changing tooling. Secure the shank to the full depth recommended by the collet or holder manufacturer to minimize runout. Verify that cutting parameters such as spindle speed and feed rate are appropriate for the workpiece material and the 13/64 inch diameter before beginning the cut.
