Accupro 12181523 Square End Mill 0.6299 in 2 Flute Carbide

Product Description

The ACCUPRO 12181523 is a solid carbide square end mill designed for precision milling operations in ferrous and hardened materials. With a 0.6299-inch (16 mm) mill diameter and a 1.2598-inch (32 mm) length of cut, this end mill delivers consistent material removal across a range of machining applications. The AlTiN coating provides excellent thermal resistance, extending tool life in high-speed and dry cutting environments. The micrograin carbide substrate offers superior hardness and edge retention compared to standard carbide grades. It is a single-end, centercutting tool, making it suitable for plunge entry and full-slot milling without a pre-drilled pilot hole.

This end mill is suited for milling centers and CNC machining operations requiring a regular-length tool with a 16 mm shank. It is commonly used in job shops and production environments machining steel, stainless steel, cast iron, and similar materials. The 40-degree helix angle improves chip evacuation and reduces cutting forces, making it effective in both roughing and finishing passes. The right-hand cut and right-hand spiral flute configuration is standard for conventional CNC mill setups.

Key Features

• Solid micrograin carbide construction for extended tool life and edge retention
• AlTiN finish for high-temperature resistance in ferrous and hardened material cutting
• 40-degree helix angle promotes efficient chip evacuation and reduced cutting forces
• Centercutting design allows plunge entry without a pre-drilled hole
• Right-hand cut and right-hand flute direction compatible with standard CNC spindle rotation
• Regular length classification for general-purpose milling depth requirements

Compatibility

Designed as an OEM-style tooling solution for CNC vertical machining centers and milling machines accepting a 16 mm (0.6299-inch) straight shank end mill with standard ER or side-lock toolholders.

Installation Notes

Installation should be performed by a qualified machinist or CNC tooling technician. Ensure the machine spindle is fully stopped and the tool-change mode is engaged before mounting or removing the end mill. Use an appropriate toolholder and confirm runout is within acceptable limits before beginning a cut. Follow shop-standard torque procedures for the toolholder style in use.
